Clutch Release Bearing VKC3615,50TKB3505BR,50SCRN40P-4,31230-35070 For TOYOTA 1073-1CSR50

This clutch release bearing assembly is specifically designed for Toyota commercial vehicles (model 1073-1CSR50). It consists of a bearing body (VKC3615) and its corresponding actuating arm assembly (50TKB3505BR). The core component, the clutch release bearing (50SCRN40P-4 / 31230-35070), features a maintenance-free, pre-lubricated, sealed design, ensuring smooth, low-friction rotational support during clutch operation. Its primary function is to receive thrust from the clutch slave cylinder or cable through the actuating arm when the driver depresses the clutch pedal, precisely transmitting force to the release finger (diaphragm spring) of the clutch pressure plate. This temporarily separates the clutch plate from the flywheel, thereby disconnecting engine power and facilitating smooth gear shifting. This design is designed to withstand axial and radial loads, as well as high temperatures, during operation.

This component is manufactured strictly to Toyota's original equipment specifications (31230-35070), ensuring precise compatibility with the hydraulic or mechanical clutch actuation system of the Toyota 1073-1CSR50 model. The release bearing, model 50SCRN40P-4 (or equivalent, VKC3615), offers high durability and is designed to withstand the high temperatures and stresses generated by frequent clutch operation. The drive arm assembly (50TKB3505BR), a key force transmission component, features optimized geometry and mounting interfaces to ensure effective thrust transmission and accurate travel. The entire assembly (VKC3615, 50TKB3505BR, 50SCRN40P-4) works together to provide reliable clutch release performance, smooth operation, and long service life for select Toyota commercial vehicles. It is a critical component for ensuring genuine original equipment fit during clutch system repair or replacement.
