The Devil is in the detail. This applies in particular to the details of one-way bearing systems in the automotive industry. ROLLAX ensures that the components used in one-way bearings are suited exactly to the needs of the application. Whether torque, rotational speed, slippage or geometry. The quality of the components such as rollers or clamping elements is proven in our in-house testing facility. Downtime and faults in your technical processes can, as such, be prevented. All ROLLAX products such as ball bearings or one-way bearings must be one hundred percent functional and performance proven, as faults often lead to downtime in automotive applications.

We also manufacture customer specific one-way bearings for the most diverse applications. Following is an extract of possible fields of application respectively of various one-way bearings that find use within industrial manufacturing:

When it comes to Pinewood Derby races, the performance of your car can be significantly influenced by the wheels' friction and resistance. One effective method to enhance the speed and performance of your Pinewood Derby car is by applying graphite to the wheels. Graphite serves as a lubricant that reduces friction, allowing the wheels to spin more freely. Here’s a step-by-step guide on how to properly apply graphite to the wheels of your Pinewood Derby car for optimal results.

Or do you require a high quality, reliably functioning, sleeve type one way clutch with ramp roller? In that case you can benefit from our specialised designs, generating high locking torque yet requiring very little space. When designing new models we always consider the economical benefits, a reason for equipping the sleeve type one-way clutch with needle rollers, making this design extremely cost effective.

Next, you will want to apply graphite to the wheel hubs. This is where the wheel makes contact with the axle. Take a small amount of graphite powder and apply it directly into the wheel hub. You can use your fingertip or a small brush to ensure the graphite is evenly distributed. Spin the wheel while applying to allow the graphite to coat the interior surfaces thoroughly.

One-way bearings with roller clutch and one-way bearings with sprag clutch are the most common types. The one-way bearings combine high torque and high rotational speed with stable functionality. Roller types cost less to manufacture than sprag types and as such offer a better price/performance ratio at higher volumes.

After you’ve finished applying the graphite and testing the wheels, clean your workspace and any parts that may have accumulated excess graphite. This prevents any mess on race day.

Before applying graphite, you need to prepare your wheels and axles. Start by ensuring that the wheels are clean and free of any debris, dirt, or oils. Use a clean cloth to wipe down the wheels. If you want even better performance, consider sanding the insides of the wheels and the axles lightly to smooth any imperfections.

In principle one-way bearings can be found with the most diverse functions. Whether as a standard one-way bearing, a one-way stepper feed, overrunning clutch, or overrunning freewheel, one-way bearings are versatile, both in functionality and usage.

The first step in applying graphite is to focus on the axles. Use a small brush or applicator to lightly dust powdered graphite onto the axles’ surface. Make sure to cover them completely, as this will provide a smooth surface for the wheels to rotate on.

The life of a rolling bearing is defined as the number of revolutions which the bearing is capable of performing, before any signs of fatigue are evident.

Hundreds of patents, highly qualified employees, and proprietary in-house machine and tool manufacture, provide a sound foundation for our quality products and the desired flexibility in manufacturing.

If your axles are too tight, you can use pliers to slightly widen the hole in the wheel until you achieve a snug fit that allows for free rotation without excessive play

A one-way bearing – sometimes also known as an overrunning clutch or a backstop clutch – is a crucial component, enabling different rotational speeds of shaft and environs in one direction. For instance, when overtaking. Parts of the drive train are literally disengaged or reverse is disabled. These silently running one-way bearings can follow many different designs. The following options (selected examples) are available:

Mainly sleeved one-way bearings are found in the automotive industry. Dependent on the customer specification, these sleeved one-way bearings are designed as one-way clutches. These are preferably drawn and, in comparison, with a thin walled outer ring and roller ramp. Additionally a plastic cage and spring operated needle rollers. These types of highly complex models evidence a very high degree of switching and frequency accuracy. Functionally, this type of one-way bearing transfers the full torque force in one direction, while, at the same time, transferring a very low frictional torque (in idle mode) in the other direction. In all of our one-way bearing designs around the sleeved versions, the spring contact pressure is of the upmost importance, as only when permanent pressure is applied can the switching and frequency accuracy be reliably upheld.

Once you have applied the graphite to both the axles and wheel hubs, it's time to assemble your wheels and axles. Insert the axles into the wheel hubs, ensuring that they fit snugly but still allow for smooth rotation. Spin each wheel after installation to ensure they turn freely. If there’s too much resistance, you may need to adjust the axle fit or reapply more graphite.

ROLLAX is well known as a specialist for ball bearings. It is lesser known that one-way bearings and clamping elements also belong to our core skills. Our portfolio is comprehensive and varied. We provide, for example, a bi-directional one-way roller bearing clutch, offering very high locking torque. Activation via decoupler wheel. Uni-directional or bi-directional one-way clutches are used when the full torque passes through from the direction of drive. Forces from the other direction are securely blocked. This is important for adjusters when the new position needs to be held. (e.g., seat height adjuster, comfort adjuster)

Creativity and expertise are our major competitive assets. Holistic thinking and challenging the boundaries of existing knowledge are integral to our company culture.

After assembling everything, perform a few test runs without racing to see how the wheels perform. It's advisable to allow the graphite some time to settle in, so rolling the car back and forth can help distribute the lubricant evenly.
