Value Collection 21461-77 Deep Groove Ball Bearing

Product Description

The VALUE COLLECTION 21461-77 is a deep groove ball bearing designed for radial and light axial load applications in rotating mechanical assemblies. It features a 0.312-inch bore diameter, a double-shield construction that protects internal components from contaminants, and a single-row configuration suited for space-constrained installations. The bearing carries a dynamic load capacity of 450 pounds and a maximum operating speed of 2,500 RPM. Built with a carbon steel housing and an unground retainer type, it is a standard replacement-grade component installed by maintenance technicians and mechanical trades in industrial and light commercial equipment.

This bearing is appropriate for use in motors, pumps, fans, conveyors, and similar rotating equipment where a small-bore, shielded ball bearing is required. The 0.312-inch round bore fits standard shaft sizes in that range. The double-shield design makes it well suited for environments with dust or debris exposure where an open bearing would be at risk. It is sold as an individual unit and is stocked for single-unit purchase.

Compatibility

Designed as a standard replacement deep groove ball bearing for rotating equipment requiring a 0.312-inch round bore, double-shield, single-row bearing in industrial and light commercial applications.

Installation Notes

Bearing installation and replacement should be performed by qualified mechanical maintenance technicians. De-energize and lockout all power sources before beginning work on any rotating assembly. Use proper bearing drivers or a press to seat the bearing evenly into the housing bore — never strike the bearing directly with a hammer. Ensure shaft and housing surfaces are clean and within tolerance before installation.
