When selecting split bearings, several crucial factors must be carefully considered to ensure optimal performance and longevity. Firstly, evaluating the load capacity and operating conditions is paramount. Different applications may subject bearings to varying loads, speeds, and environmental factors, necessitating the selection of split bearings with appropriate load ratings and materials capable of withstanding the anticipated conditions. For instance, heavy-duty industrial machinery may require split bearings with higher load capacities to withstand the substantial forces generated during operation, while applications in corrosive or high-temperature environments may necessitate bearings constructed from corrosion-resistant materials or equipped with specialized seals to prevent contamination. Factors such as radial and axial loads, shaft speeds, temperature variations, and exposure to contaminants must be taken into account to determine the most suitable bearing specifications for the specific application.

(Pinarello's North American distributor, Gita Sporting Goods, advises: "the F4:13 is sold as a frame and fork, allowing the buyer to spec the bike to his/her personal preference".)

One of the primary benefits of split bearings lies in their maintenance and accessibility features, which contribute significantly to streamlined machinery upkeep and reduced downtime. Unlike traditional bearings, split bearings can be conveniently disassembled into two halves, facilitating easy access to internal components for inspection, lubrication, and replacement without the need to dismantle surrounding machinery or disengage shafts entirely. This accessibility not only simplifies routine maintenance tasks but also minimizes the time and labor required for bearing-related interventions, thereby optimizing operational efficiency. Furthermore, split bearings offer enhanced flexibility in installation and replacement processes, allowing maintenance personnel to swiftly address issues and restore machinery functionality without prolonged disruptions to production schedules. By reducing the complexity and duration of maintenance procedures, split bearings enable organizations to maintain consistent operational uptime, enhance equipment reliability, and maximize overall productivity. This accessibility feature makes split bearings particularly well-suited for industries where uninterrupted operation is paramount, such as manufacturing, power generation, and transportation.

On test: Pinarello F4:13, October 28, 2005 One piece wonder Pinarello's F4:13 is the company's first foray into carbon fiber monocoque construction and feels like it turns every iota of effort into forward motion, says Chris Henry. Pinarello F4:13 Pinarello has been slow to jump aboard the all-carbon juggernaut, preferring to concentrate on its highly-regarded magnesium-frame technology as showcased in the Dogma series of bikes. But the attraction and momentum of carbon is unavoidable, and while the all-carbon F4:13 hasn't displaced the Dogma at the top of Pinarello's line-up, it is clearly a serious and purposeful attempt to use the material's properties to best advantage, starting with one-piece main frame construction to exploit carbon's stiffness and low weight. A stiff, performance-oriented racer at heart, the F4:13 slots in the mid to upper range of the Pinarello line and proves itself worthy of the position. The shift in design from Pinarello's recent offerings is evident immediately. Big tubes and interesting lines set the F4:13 apart from the traditional stock, not to mention the increased surface area on the downtube for bold Pinarello branding. The frame is currently available in six sizes, with top tube lengths ranging from 51.2cm to 59cm. First impressions Selle Italia SLR XP seat Pinarello stem Deda bar and stem Campagnolo Centaur brakes Campagnolo Chorus rear derailleur Campagnolo Eurus wheels 50-34 compact cranks Pinarello Onda fork The down tube is huge Shaped "tubes" Campagnolo Chorus brake levers Selle Italia SLR XP saddle I initially expected the F4:13 to give me some fit problems. It looks short, and the relatively short 110mm stem and the stubby Campy brake levers created an illusion that I was bunched up on the bike. But when I adjusted the saddle to my usual setback and height, I fit rather well on the bike, solving that end of the equation fairly easily. Early rides with the F4:13 made me realise too that the handling, while superb, is somehow different than that to which I am accustomed. The 43mm offset of the Pinarello's Onda fork, combined with a 73 degree head angle (for a 55cm frame), makes for very agile steering. Yet the bike doesn't feel too nervous at all. It's as if it reacts with zero hesitation to your slightest nudge, yet doesn't get carried away and steer you off your course or prompt an anxious urge to correct any wobbles. I found the handling differences revealed themselves most when riding on the drops, out of the saddle (sprinting or just getting that bit of extra power along the way). Part of this was also due to the shape of the Deda Newton bars, with a very steep angle in the 'ergo' bend of the drops. How much of a difference in comfort or handling the Onda rear stays make, I'm not sure, but they look distinctively Pinarello, so that counts for something. Components Our F4:13 came equipped with a mix of components. Campagnolo's Chorus group provided the braking and shifting, while the brake calipers were Centaur, not that I noticed any difference there. In fact, the braking was quite powerful yet generally smooth and easy to vary between full-on stops and minor changes in speed on a descent. However, at slow speeds, such as in traffic, the brakes tended to grab somewhat and felt a bit jerky. When rolling under faster, more ideal circumstances, the ability to feather the brakes and moderate speed - or stop on a dime - was more impressive. Pinarello slapped its name on a Deda stem, paired with Deda's Newton handlebars, and provided a carbon fiber seat post. I stuck with the Selle Italia SLR XP saddle for this test. I'd tested this saddle in the past and knew it to be comfortable for me considering its light weight, although as a fairly short saddle it doesn't offer much room to shift around in different riding situations. The drivetrain for the F4:13 includes FSA's carbon compact crank (50x34) and a 12-23 cassette in the rear. Campagnolo Eurus clincher wheels keep the bike rolling, paired with Gommitalia Calypso tires. On the road The enormous downtube and one-piece design of the F4:13 mean one thing: this bike is stiff! The F4:13 is the type of bike that lets you feel that every ounce of force you put on the pedal is going into making you move. In the saddle, but particularly out, acceleration comes instantly on the bike. Nowhere did I feel this most than on the up and down of short rolling hills, when that extra kick out of the saddle to keep the momentum on the upswing becomes the most fun part of the ride. The flipside to this, of course, is that the bike does not feel very forgiving. My experience is that, in general, a stiff carbon bike will still be more comfortable than a stiff aluminium bike. Carbon frames and forks generally damp a bit more vibration, while remaining fairly stiff and light. However, of all the test bikes I've had the pleasure to ride in the past few years, this was the most demanding physically. I didn't feel as though I'd been put through the ringer or left jarred by the experience after a ride, but my hands and arms did let me know that they were doing a bit more than usual to soak up the bumps. For some riders, the extreme stiffness of a bike like the F4:13 outweighs the disadvantage of its slight harshness. Others like a softer ride. Clearly there's a point of preference, but it's worth noting that even a beautifully made carbon bike can rattle the bones a little. Of course this concept is the equivalent of sports suspensions on cars, and this bike leaves nothing on the road, as they say. If you want to ride quickly, and you've got the strength to do it, the F4:13 won't do a thing to get in your way. For me, the component choices may have played into my perceptions of this bike too. I have a personal preference for Shimano shift levers over Campagnolo, as the softer and more ergonomic shape of Dura-Ace levers is, to my hands, much more comfortable than the Campy equivalent. Campagnolo's levers features a very notable outside edge under the rubber cover that seems to dig into my palm when riding on the hoods, which just happened to be the position I found most natural on this bike. Furthermore, the Deda Newton stem and handlebar were not quite my cup of tea. I prefer a more shallow drop in the handlebar, and the relatively deep drop of the Newton, combined with the test bike's lower stem height, meant that I spent most of my time on the hoods rather than in a somewhat forced tuck. The bars also felt quite thin in diameter, giving my hands less to wrap themselves around when riding on the tops of the bars. This is another example of personal preference as opposed to a commentary on the quality of Deda's equipment, which has been the choice of numerous professional teams over the years. I also didn't get on with the 50x34 compact cranks. The trend may be on the rise, as more bikes are sold with compact cranks and more manufacturers take their own crack at the modified design, but personally I'm happy with more conventional front chainrings. I found myself double shifting too much on the rolling terrain, spending more time thinking about how to find the right gear than how to get up the hill at an acceptable pace. The frame didn't slow me down but I'd say the shifting did. Of course there's an adjustment to this set-up as there is for many things, but in the end I never quite got there. Despite this critique, I did manage to set a personal best on a local 1 mile climb on the F4:13. Maybe because it's a 'find the right gear and go' kind of climb. For that I'll choose to thank the frame and leave the gearing aside. Overall impressions All in all, I found the F4:13 to be a superb bike when it comes to pure speed and performance. Typical rides in the 2.5 to 3 hour range featured plenty of modest hills, some fast rolling flats, and enough pothole dodging to give credit to the nice front end handling, once I became accustomed to the Pinarello feel. A few too many quirks in components, coupled with the super stiff ride of the F4:13, prompt me to give it a four-jersey rating as opposed to anything higher. I loved the frame, but given a choice would have built it up with a different set of components (as any owner can do). There's no doubt this is a solid performer and for a pure racing machine it's a good choice. However, if your riding includes some racing or fast recreational training, but also plenty of long hours in the saddle on less intense rides, this may not be the perfect frame for you. Objectively speaking, the F4:13 provides pure-bred performance, competitively light weight, and contemporary Italian styling, making it a worthy contender in the battle of the high end racing bikes. (Pinarello's North American distributor, Gita Sporting Goods, advises: "the F4:13 is sold as a frame and fork, allowing the buyer to spec the bike to his/her personal preference".)

Split bearings, also known as split-block or split-housing bearings, represent a significant innovation in the realm of machinery maintenance. Unlike traditional bearings, split bearings feature a design that allows them to be easily disassembled into two halves, simplifying installation, maintenance, and replacement processes. This unique construction consists of an inner ring, outer ring, and rolling elements, with the housing split along the horizontal or vertical axis. This division facilitates accessibility to the bearing components without requiring the disassembly of surrounding machinery or shafts, making split bearings particularly advantageous in applications where downtime must be minimized. Split bearings are widely used across various industries, from manufacturing and automotive to marine and aerospace, offering enhanced flexibility and efficiency in machinery upkeep.
