The 50TKB3504BR Clutch Release Bearing acts as the critical connection between the moving clutch mechanism and the stationary transmission housing in manual vehicles. Based on its nomenclature, the "TKB" designation indicates it is a self-centering clutch bearing equipped with a resin sleeve. This self-centering capability allows the bearing to automatically align with the diaphragm spring, reducing noise, vibration, and premature wear on the clutch components.

The 50TKB3504BR provides several advantages that appeal to auto repair shops and aftermarket distributors:
Self-Centering Technology: The "TKB" design dynamically adjusts to misalignments between the transmission input shaft and the engine crankshaft, preventing clutch judder.
Resin Sleeve Design: The use of a resin (polymer) sleeve on the sliding surface lowers friction against the transmission guide tube compared to traditional steel sleeves, ensuring smoother pedal feel and reducing wear on the guide tube.
Pre-Lubricated: Factory packed with high-temperature, long-life grease to withstand the thermal loads generated during frequent clutch engagements in heavy traffic.
With an inner bore of 35 mm and crossing to TOYOTA OE part number 31230-35090, this throw-out bearing is designed for a variety of passenger cars and light commercial vehicles equipped with manual transmissions. It is widely purchased by auto parts wholesalers, clutch kit rebuilders, and fleet maintenance providers looking for OEM-quality replacement parts.
We understand the needs of global auto parts sourcing. We offer comprehensive OEM services, including laser marking your brand or part number (e.g., your internal SKU instead of 50TKB3504BR) directly on the bearing. Packaging is entirely customizable "As Customer Required," ranging from cost-effective bulk industrial packing to individual, retail-ready color boxes with custom barcodes.
Our pricing is highly competitive and negotiable based on order volume. To receive a fast B2B quotation, please send an inquiry including:
The bearing part number (50TKB3504BR or 31230-35090).
Your required order quantity.
Any specific OEM marking or customized packaging requirements.
Your destination port or zip code for shipping estimation.
Q1: What does "TKB" mean in the part number 50TKB3504BR?
A: According to the naming convention, "TKB" denotes a Self-Centering, Resin Sleeve Type clutch release bearing, designed for low-friction sliding and automatic alignment.
Q2: Is this a direct fit for Toyota 31230-35090?
A: Yes, the 50TKB3504BR shares the same 35x71x44 mm dimensions and 50 mm contact diameter, making it a direct aftermarket equivalent for 31230-35090, VKC3616, and RCT356SA9.
Q3: Can I order a sample before committing to a wholesale order?
A: Absolutely. We provide sample bearings so your engineering or QC team can evaluate the resin sleeve sliding action and overall build quality.
Q4: Can you package these to match our brand's clutch kits?
A: Yes. We routinely supply clutch release bearings in customized boxes or neutral packaging to match our clients' existing clutch kit branding strategies.
