For a vacuum environment we suggest the outer/inner rings and balls are made of martensitic stainless steel. For corrosion resistance we suggest precipitation hardening steel be used. You should specify high speed tool steel for the best heat resistance. As in most Vacuum applications cleanliness is important so we suggest using polymeric lubricants or fluorinated grease.

It really doesn’t make a great deal of difference to the bearing if the wheel is driven or not . The non driven wheel rotates on the axle, the driven wheel rotates with the axle. In both cases the bearing allows free rotation between the axle and hub. A gushing would work also but would have more drag and wear out much quicker. You can see the difference in cheap lawnmowers with bushings and expensive ones with bearings. The expensive ones push easier and smoother.

I was replacing the 52 because cold weather was coming because the rocker panel, Bottom of B pillar and all the floor outside the frame rais were gone from rust.

High Corrosion Resistant Ceramic Bearings: are suitable for applications operating in acidic or alkaline environments or in corrosive gas environments.

Many conventional lubricants break down at high temperatures, leading to increased friction and wear. High-temperature applications often require specialized lubricants, such as high-temperature greases or solid lubricants like graphite or molybdenum disulfide. Selecting the appropriate lubricant is essential for ensuring proper lubrication and minimizing wear at elevated temperatures.

The purpose of a forum like this is to ask any and all the questions you like. I never really encountered any stupid mechanical questions but I have witnessed some silly superstitions and or half truths in the mechanical realm… so ask those questions as that is how we get rid of those types of things.

…and there are no stupid mechanical questions. The really stupid ones are the ones who think they know and are too proud to ask… and waste no time really tearing things up and breaking things. Never be too proud to ask.

When I bought my first car , a $20 dollar, 52 Plymouth, I knew nothing about cars. I had replaced a head gasket on a 47 Fraser but that was under my stepfathers supervision. The only reason I was doing it was because I had blown it the day I got my learners permit at 16. I had been driving for 4 years but very cautiously because I did not have a license. Once I got my permit, all bets were off.

Ceramic Bearings: are suitable for applications operating in slightly acidic or alkaline environments or in reactive gas environments.

Identify the maximum and continuous operating temperatures of the application . Different bearing materials have temperature limits. Improper material selection can lead to permanent deformation, rapid degradation and failure. Full ceramic bearings may withstand temperatures up to 1600°C, while specially treated stabilized high-temperature steel bearings are limited to around 500°C.

Ballbearing definition

Yeah, I read about the full-floating vs semi floating systems, and I’ve also seen how the axle can extent to the wheel, or it mounts to the bearing inner race or even goes farther out to the wheel itself. They’re all generally the same though, right? (with a bearing that connects to the axle and to the wheel hub)?

The bearing goes between the knuckle and the axle. The knuckle is the fixed, non rotating part that is attached to the vehicle through the ball joints and control arms. The axle goes through the middle of the knuckle. The outer race is attached to the knuckle, the inner race attached to the axle via the hub. The ball or needle bearing allow the axle/wheel to turn smoothly while the knuckle holds the wheel in place in relation to the vehicle.

Google FWD bearing cutaway, click on the images tab. There are drawings there. Typical bearing designs these days are 2 rows of angular contact ball bearings pressed into the knuckle or built into a bearing and hub assembly. They do the exact same task on the driven axle as they do on a non driven axle.

Bearings made of 440C bearing stainless steel are suitable for operation in clean environments when the preservative oils are removed. Additionally replacing the steel balls with ceramic balls enhances performance and longevity. Adding grease or oil is possible as long as it has low particle emissions. Many times a small amount of fluorinated oil can be applied to the bearing for safe use in clean environments.

For extreme temperatures and harsh environments where conventional lubricants are ineffective, NSK offers SJ High-Temperature Bearings with Solid Lubricant. These bearings utilize solid lubricants, such as graphite or molybdenum disulfide, which provide effective lubrication even at temperatures exceeding 500°C. Solid lubricants are also highly resistant to chemical degradation and offer excellent performance in corrosive environments.

Study the various methods of attaching the wheel to an axle in the link. The bearing is between the axle and wheel on quite a few but totally separate on others. There is no simple answer.

Ceramic materials boast exceptional thermal stability, allowing ceramic bearings to withstand temperatures of up to 1600°C, far exceeding the capabilities of bearing steel. This increased level of heat resistance makes ceramic bearings ideal for applications in furnaces, kilns, and other high-temperature environments. Please keep in mind full ceramic bearings do not have the load capacity of steel bearings and must be sized properly before using them.

Bearings with steel rings and ceramic balls are Hybrid bearings and are often of higher precision than standard. When selecting a lubricant the temperature of the application is your guide:

Bearings which need to operate in corrosive environments will need to be made of special materials. The selection of any brand full Ceramic bearing for the use in a highly corrosive environment should be specified with the knowledge that full ceramic bearings have significantly lower load ratings than standard bearings.

You will see the difference that you may have confused yourself with by looking o line for cutaway drawings of say a FWD axle and wheel bearing… and then comparing that to a solid axle (“rear end”) and how its bearing interfaces the internal axle. A vehicle to look up would be say a 90’ Mustang with a solid rear axle or a 80’s-90’s Ford F150… a 80’s-90’s Camaro etc… There are plenty other examples of vehicles that have a solid rear, so… Solid rear axle is what u need to compare to but I think you probably have it all worked out

These bearings are particularly well-suited for applications in kiln trucks, roller hearth furnaces, and bakeries, where high temperatures are common. The robust design and specialized materials used in SKF high-temperature bearings ensure reliable performance and extended service life, even under demanding thermal conditions.

I was standing there looking puzzled and wondering what had gone wrong and my mother in law walked out of the house, tool one look and said “where is your fan belt?”

Ok, I might understand this. So, the bearing really has nothing to do with the axle itself, it just sits where the main hub is, making sure that the axle can rotate freely without any real resistance. I thought the bearing was inbetween the axle and the wheel. I think I understand this now

Unlike steel, which expands significantly with increasing temperature, ceramic materials exhibit minimal thermal expansion. This characteristic ensures consistent performance across a wide temperature range, reducing the risk of seizure and dimensional deformation.

I think what I was thinking was that the bearing was an attachment where the axle would meet up with the wheel, I’m not sure exactly where I got that idea, but I think I know now how the bearings work, how they are mounted, etc. I did look up solid rear axles and surely enough, its basically the same bearing idea, just with the axle being solid instead of split like in a FWD car. And btw, I won’t try to ask too many questions on here (to prevent clogging up the forum lol), only the ones I need help figuring out.

Ceramic materials are naturally resistant to corrosion, making them highly suitable for operation in harsh environments where exposure to chemicals or moisture would quickly degrade conventional bearings. This property is particularly valuable in chemical processing and other corrosive applications.

LOL, I know a few things about cars now, but last year when I bought my first car, I didn’t even know how the camshafts worked. Luckily now, I’ve done a decent amount of research and if I get another car soon, it’ll probably be really easy to work on since I know a lot more than I did last year.

Bearings must be able to handle the determined loads and speeds at the operating temperature. Each bearing type has specific load capacity and speed limitations, which can decrease at higher temperatures. Engineers must choose  bearings and its materials and lubrication  that can accommodate the anticipated loads and speeds without compromising performance or longevity.

While high-temperature ceramic ball bearings offer significant advantages, it’s important to consider their higher cost compared to conventional bearings. Additionally, ceramic materials can be more brittle than steel, requiring careful handling and installation to prevent damage.

Also full ceramic bearings offer about 30%-50% of the load rating of standard steel bearings. You must be aware of the reduced load ratings of full ceramic bearings versus Hybrid ceramic ball bearings which meet or exceed steel ball bearing speeds but are about equal for  load ratings.Please contact Pacific International Bearing Sales Inc at [email protected] for further assistance.

High-temperature bearings are designed to withstand extreme thermal conditions while maintaining their structural integrity and performance. These bearings are essential for ensuring the reliable operation in extreme and demanding applications where conventional bearings would fail prematurely.

Corrosion Resistant Ceramic Bearings: are suitable for applications operating in acidic and alkaline environments or in reactive gas environments.

How do ball bearings workphysics

Bearing material must be compatible with the materials of the housing and shaft to prevent seizing or excessive wear. Thermal expansion rates of different materials should be considered to avoid issues like bearing seizure due to differential expansion. For example, using a ceramic bearing with a steel shaft requires careful consideration of the different thermal expansion rates to prevent potential problems.

Corrosive gasses, dust, and other contaminants can significantly impact bearing life. Special materials or coatings might be necessary to protect the bearings from these harsh conditions. For instance, bearings operating in highly corrosive environments might require specialized coatings or be manufactured from materials with inherent corrosion resistance.

I know this is a sort of… newbie question, but how do drive wheel bearings work? I think I know how non-drive wheel bearings work, since they really don’t have a shaft that spins as in the drive wheels, but I’m sort of unsure about drive wheel bearings. I know where the bearings are located, and I know how a bearing works, but I’m not sure what the purpose of a drive wheel bearing is, because from what I understand, the axle is still directly paired to the main wheel hub, but the bearing just sort of makes a smooth surface for the axle to run through? A diagram would be appreciated!
