Product Description
WPC - Surface Treated Rod Bearings - S63 S63TU BMW F10 F12 F13 F85 F86 M5 M6 X5M X6M
These OEM BMW rod bearings feature the WPC surface treatment and are specific for the S63 and S63TU
WPC is a proven process that has been utilized for many years in the racing and automotive industry. WPC is not a coating, it is a treatment that enhances the surface to reduce friction and strengthen engine parts. WPC achieves this process by firing ultra fine particles towards the surface of a product at very high speeds. The resulting thermal discharge permanently changes the surface, strengthening structure and creating a harder more durable final product.
The WPC process is unrivalled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part. It's unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment.
The fine grooves, that are intrinsically engraved into the product surface at the time of machining, are transformed into micro-dimple indentations by the impact of the ultra-fine media during WPC treatment. These dimples then act as oil reservoirs. Thus, oil that would normally drain away, through the grooves in an untreated product, when pressure is applied, is instead retained in the dimples of a WPC treated product. This helps to keep the surface lubricated.
As with all bearings, check your tolerances and size before installation. Due to the specialized tools needed, professional installation is recommended.
There are no returns available on any engine bearings.
Test results on WPC treated bearings have shown improvement in bearing load bearing capacity and a reduction in bearing wear:
