Overview
This deep groove ball bearing is engineered for high-speed industrial applications requiring precise rotational movement and reliable load support. Designed with a 1.969-inch bore and a 3.543-inch outside diameter, the unit features a compact 0.787-inch width that fits seamlessly into space-constrained machinery assemblies. Constructed from high-grade steel, the bearing offers exceptional durability and resistance to deformation under heavy radial and axial loads. The design incorporates dual rubber seals on both sides to effectively retain internal lubrication while excluding dust, dirt, and moisture, significantly extending service life in harsh operating environments. Furthermore, the C3 internal clearance specification provides additional room for thermal expansion and accommodates minor shaft misalignment, ensuring smooth operation even when temperatures fluctuate or installation tolerances vary. This component is an essential replacement or upgrade part for electric motors, gearboxes, pumps, and conveyor systems where consistent performance and reduced maintenance intervals are critical.
