Designed specifically for the Toyota 1074CSR50, this clutch release bearing utilizes a high-precision needle roller bearing structure, with core components constructed from a composite of porous metal and high-strength alloy steel. The porous metal matrix achieves self-lubrication through a hot oil impregnation process. During operation, the pumping effect generated by the shaft journal rotation and the temperature rise of the bearing combine to continuously replenish the lubricant to the friction surface, significantly reducing mechanical wear during release. The bearing's outer ring features a semi-enclosed rib design, combined with a curved roller end face structure, effectively dissipating stress concentration caused by axial loads, ensuring structural stability and extending service life despite frequent clutching operations.
This product strictly adheres to Toyota OE standards (OE No. 31230-35050) and is compatible with a variety of classic Toyota models, including the MR2, Celica Coupe, and Corolla Liftback. The core model, the 50SCRN34P-4, is dual-certified by ISO9001/TS16949. The rollers and raceways utilize a line contact design, increasing the contact area by 40% compared to point contact, significantly enhancing radial load capacity. The inner ring of the bearing and the journal adopt a 100-130℃ thermal expansion interference fit process, and the outer ring and the shaft box are precisely sliding fit, ensuring no axial movement during power transmission. At the same time, it supports rapid disassembly and maintenance, meeting the after-sales market's dual needs for efficiency and reliability.
