NATIONAL 370169A Tapered Roller Bearing - Heavy Duty Truck Hub & Axle Assembly
The NATIONAL 370169A is a high-performance single-row Tapered Roller Bearing (TRB) engineered for demanding industrial and commercial vehicle applications. Featuring a robust design with a nominal bore diameter (d) of 95.25 mm (3.750 in), an outer diameter (D) of 146.05 mm (5.750 in), and a total width (T) of 49.21 mm, this bearing utilizes precision-ground rollers and raceways crafted from high-carbon bearing steel (SAE 52100 equivalent). This construction ensures exceptional rigidity and the ability to manage simultaneous heavy radial and significant axial loads in one direction, critical for proper alignment and minimizing friction losses in high-torque environments.
Optimized for use in heavy-duty hub assemblies, differentials, and industrial gearbox applications where uptime is paramount. The NATIONAL 370169A delivers superior operational lifespan and reduced maintenance requirements compared to standard bearings. As part of the trusted NATIONAL bearing line, this unit ensures reliable, long-term performance under extreme temperature fluctuations and high-shock loading, making it the preferred choice for fleet managers and industrial maintenance professionals focused on maximizing efficiency and component durability across key power transmission systems.
