32311

The 32311 single-row tapered roller bearing is a high-precision metric component designed to handle demanding mechanical environments where combined radial and axial loads are prevalent. Featuring a standard 55mm bore, 120mm outside diameter, and a total width of 45.5mm, this bearing utilizes an optimized internal geometry to manage force vectors with minimal friction. Its unique separable design-consisting of the inner ring with roller assembly (cone) and the outer ring (cup)-allows for independent mounting, which significantly simplifies installation and routine maintenance in complex machinery setups.

Engineered from high-grade chrome steel and subjected to rigorous heat treatment, the 32311 model excels in high-torque applications such as industrial gearboxes, automotive wheel hubs, and heavy-duty agricultural equipment. Its tapered rollers are specifically angled to provide a high degree of stiffness and long-term reliability under shock loads. Whether integrated into a truck axle or a mining conveyor system, this bearing ensures smooth rotational performance and high resistance to wear, offering an efficient solution for reducing operational downtime in critical power transmission systems.
