Koyo RCT356SA9 Clutch Release Bearing

The Koyo RCT356SA9 is a precision-engineered clutch release bearing designed for reliable performance in manual transmission applications. This bearing plays a critical role in clutch operation by reducing friction between the release fork and clutch pressure plate levers during gear engagement, preventing premature wear and ensuring smooth clutch operation.

Key Features:

• Inner diameter: 35mm with optimized bearing geometry for proper clutch fork fitment
• Outer diameter: 70.25mm designed to interface seamlessly with pressure plate assemblies
• Height: 44.4mm providing proper engagement clearance
• Manufactured from chrome steel (GCR-15) for exceptional durability and wear resistance
• Thrust angular contact ball bearing design optimized for axial loads
• ISO/TS 16949 certified manufacturing ensuring consistent quality standards
• Cross-references to OEM part numbers including 31230-35090, 50TKB3504BR, VKC3616, and 50SCRN44S-2

Koyo bearings are manufactured to meet or exceed strict OEM quality requirements, with many Koyo components serving as original equipment for vehicle manufacturers. This release bearing is commonly used in Toyota applications including Hilux, Prado, Innova, HiAce, and Unser models, though proper fitment verification is essential for your specific application.

The RCT356SA9 features precision P5 rating tolerances and steel cage construction for extended service life under demanding clutch operation conditions. When you experience symptoms like clutch shuddering, grinding during shifts, or abnormal clutch engagement, a worn release bearing is often the culprit.
