32TM12E Double Rubber Sealed CVT Pulley Gearbox Bearing

32TM12E non-standard TM series deep groove ball bearing, dimension 32.2×84×15mm, dedicated to JATCO JF010E CVT primary drive pulley. Double-side reinforced green rubber contact seals block gear oil leakage and fine dust intrusion. Standard C0 internal clearance, deep groove raceway bears radial load and minor bidirectional axial load, stable low-noise high-speed rotation under continuous CVT variable-speed vibration. Fully quenched high-purity GCr15 bearing steel with tight dimensional tolerance, fully interchangeable with original OEM 32TM12E. Complete formal quotation will be provided within 24 hours upon inquiry.

• Upgraded green multi-lip NBR rubber seals, excellent oil resistance, no swelling or aging under long-term CVT gear oil soaking
• Optimized internal raceway geometry, low rolling friction, stable operation under frequent variable-speed impact
• Purified GCr15 chrome steel with uniform high hardness, outstanding anti-fatigue and wear resistance to extend CVT service life
• OEM matching overall dimension, direct replacement without modifying pulley and gearbox housing parts
• Lightweight stamped steel cage reduces rotation inertia, adapts to long-duration high-speed CVT working conditions
• Standard P0 precision, customizable P6 grade to meet automotive CVT OEM assembly standards
