The break-in process
Upon first installing Simplicity self-lubricating bearings, the Frelon material in the bearing experiences a break-in process. This is where small amounts of the PTFE-based liner are transferred to the surface of the shaft. In this process, a thin film of material is deposited into minute valleys or gaps in the shaft’s surface, creating a truly self-lubricating condition. No added grease or oils are required.
If the shaft is finished to less than 8 Ra, then the PTFE deposits have nowhere to settle, and end up falling away from the shaft. In this situation, the bearing liner continues to wastefully transfer material to the shaft’s surface, ending in premature liner wear and shortened bearing life.
Lessons learned
Only certified Simplicity 60 PLUS is design-matched to provide maximum performance with Simplicity self-lubricating bearings. Benefits include:
- Optimized surface finish
- Faster break-in and better Frelon transfer
- Longest life possible for Simplicity bearings
- Less downtime and maintenance
- Consistent friction over lifetime
Flexible options
Simplicity shafting, support rails, and assemblies are available in steel, ceramic coated aluminum, or 440 stainless steel. Support rails are available in both tall and low profiles. Additionally, machining options can be applied to shafting orders.
