The rollers are embedded in a silver-plated bearing ball. The silver-plated bearing race has the following advantages:
- Ölfilm adheres better to the surface
- Better heat dissipation
- Lower wear properties
Note: For crankshafts with pressed-in connecting rod bushes, a needle roller and cage assembly cannot be used retroactively.
Other needle bearings or piston pin retainers can be found in the accessories section.
