B45-106 Open Type Deep Groove Ball Bearing, Auto Gearbox Special Non-Standard Bearing

B45-106 is a non-standard open deep groove ball bearing with dimensions 45mm inner bore × 90mm outer diameter × 17mm width, specially developed for vehicle transmission and tractor gearbox differential assemblies. It adopts open structure without rubber seals and stamped steel cage with C0 standard clearance, capable of bearing radial load and two-way light axial load. The size is fully interchangeable with original matching bearing models, suitable for multiple medium-duty vehicles and agricultural transmission equipment. We will provide formal quotation within 24 hours after receiving your inquiry.

• Open structure allows smooth internal circulation of gearbox oil, excellent heat dissipation performance and stable high-speed operation for transmission assemblies.
• Deep groove raceway design bears combined radial and slight axial force, low friction coefficient and quiet operation under frequent shifting impact.
• Fully quenched GCr15 chrome bearing steel with uniform hardness, excellent fatigue resistance and wear resistance to support long-term continuous operation of gearboxes.
• Custom thin-wall overall size perfectly fits the original gearbox housing, direct replacement without equipment modification.
• Lightweight stamped steel cage reduces rotation inertia and maintains stable operation under long-term vibration and shifting impact.
• Controlled P6 precision level meets vehicle OEM standards, high matching degree with original equipment.

Differential shafts of manual and automatic automobile gearboxes, transmission assemblies of farm tractors, auxiliary reducers of light commercial vehicles, medium-speed industrial gearboxes.

Q1: What is the difference between open B45-106 and sealed bearings?
A1: The open type has no rubber sealing rings and relies on circulating gearbox oil for lubrication and heat dissipation, applicable to high-speed internal working environments of transmissions; sealed bearings are used for external dusty shafts with grease lubrication.
Q2: Can GQZ B45-106 directly replace the original matching bearing?
A2: Yes, all inner bore, outer diameter and width dimensions are completely consistent, no modification to gearbox housings or shafts is required during replacement.
Q3: What lubrication method is suitable for this bearing?
A3: It is designed for circulating gearbox oil lubrication; if used separately, high-speed anti-wear gear grease needs to be filled.
