28TM11 Double Rubber Sealed Deep Groove Ball Bearing, Auto Transmission Special Bearing

28TM11 is a TM series special deep groove ball bearing sized 28mm bore × 58mm outer diameter × 16mm width, matched for automobile and agricultural machinery gearbox auxiliary shafts. Double-sided reinforced rubber contact seals block fine dust and prevent internal gear oil leakage. Standard C0 internal clearance, deep groove raceway bears radial load and bidirectional light axial load, runs smoothly and quietly under long-term high-speed shifting vibration. Fully quenched GCr15 bearing steel with stable dimensional tolerance, fully interchangeable with original 28TM11 bearings. Complete formal quotation will be provided within 24 hours upon inquiry.

• Double reinforced rubber sealing structure, good dust-proof and oil-sealing performance, avoid lubricant loss and dirt intrusion inside semi-sealed gearboxes.
• Deep groove raceway design bears combined radial and slight axial force, low friction coefficient, stable operation under frequent gear shifting impact.
• High-hardness full heat-treated GCr15 chrome steel, excellent wear and fatigue resistance, extend transmission assembly service life.
• Standard unified overall dimensions, direct replacement without modifying gearbox housings or shaft parts.
• Optimized stamped steel cage with small rotation inertia, adapts to continuous medium-high speed transmission working conditions.
• Optional P0/P6 precision grades, fully meet OEM vehicle transmission assembly matching standards.

Automotive manual & automatic gearbox auxiliary shafts, farm tractor transmission assemblies, light commercial vehicle reducers, medium-speed agricultural machinery transmission components, general industrial gear reduction devices.
