Thrust bearing from OS Giken. This is an extra sturdy and extra durable bearing without plastic parts with a larger bearing and therefore also suitable for heavier couplings.
The OS Giken thrust bearing is higher (35mm) and therefore compensates a larger piece than the standard bearing (25mm). This may be necessary if you go from a dual to a single mass flywheel and therefore reduce the height of the clutch.
For example for E30 325i or E36 325i.
