Ø inner: 13 mm
Ø outer: 17 mm

The rollers are embedded in a copper-plated steel bearing block. The copper-plated bearing cage has the following advantages:
- Oil film adheres better to the surface
- Better heat dissipation
- Lower wear
Caution: For crankshafts with a pressed-in connecting rod bushing, a needle roller and cage assembly cannot be used retroactively.
Quality product from the Italian manufacturer Polini.
