- Best used for light duty torque applications that require a one way clutch
- RC (inch) and FC FCS FCL (metric) are clutches capable for rotational torque only
- RCB (inch( and FCB FCBL (metric) are clutch bearings capable for rotational torque and radial load
- "-FS" in the suffix for the RC and RCB call out stainless steel springs and are capable of higher operating temperatures and significantly higher engagements per minute
- A polymer spring is standard for the RC and RCB
- A stainless steel spring is standard for the FC FCS FCL FCB and FCBL
- A hardened and machined shaft or an "IR" Inner Ring is required for optimal performance
- A press fit into the housing is required
How do I choose the right type of bearing for my application?
Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
