Welcome to Linqing Xinshengdi Bearing Co., Ltd.
DAC458441 Heavy-Duty Auto Wheel Hub Bearing 45x84x41mm
- Extreme Load Capability: The expanded 45x84x41mm dimensions provide a massively wide footprint for the double-row ball complement, significantly improving weight distribution during heavy braking and towing.
- Artisan-Level Manual Assembly: At Linqing Xinshengdi Bearing Co., Ltd., we operate without rigid automated production lines. Our technicians manually press and assemble each heavy-duty unit. This hands-on process prevents the micro-fractures in the raceway that automated heavy machinery can sometimes cause.
- Thermal Stability: Pre-filled with premium synthetic chassis grease designed to maintain optimal viscosity under the high temperatures generated by heavy vehicle loads.
- Maximum Contaminant Defense: Upgraded multi-lip contact seals lock out abrasive road dust, mud, and deep water, extending the bearing's operational life in tough environments.
