Value Collection 21161-77 Deep Groove Ball Bearing

Product Description

The VALUE COLLECTION 21161-77 is a single-row deep groove ball bearing designed for light-load rotational applications in industrial and mechanical assemblies. With a 0.187-inch bore diameter and a round bore style, this bearing accepts standard shaft sizes in compact drive and support configurations. The double-shield design protects internal raceways from contamination without adding significant drag. The carbon steel housing provides adequate strength for general-purpose duty with a rated dynamic load capacity of 300 pounds and a maximum operating speed of 2,500 RPM. Licensed technicians and millwrights install this type of bearing in motors, pumps, fans, and light conveyor assemblies.

This bearing is suited for residential and light commercial mechanical applications where a small-bore, shielded ball bearing is required. Typical installations include fractional-horsepower motor shafts, small gearboxes, appliance drive assemblies, and HVAC blower wheel hubs. The 0.25-inch width keeps the overall footprint narrow, making it practical for space-constrained bearing pockets. It is sold individually and intended for direct OEM replacement or aftermarket service work where a standard deep groove profile is specified.

Key Features

• 0.187-inch round bore diameter fits compact shaft diameters in light mechanical assemblies
• Double-shield configuration reduces ingress of dust and debris without requiring lubrication replenishment
• 300-pound dynamic load capacity rated for general light-duty radial loads
• 2,500 RPM maximum speed rating suitable for fractional-horsepower drive applications
• Carbon steel housing construction provides consistent dimensional stability
• Unground retainer type keeps cost appropriate for standard replacement service

Compatibility

Designed as an OEM-style replacement for light-duty mechanical assemblies requiring a single-row deep groove ball bearing with a 0.187-inch round bore and double-shield configuration.

Installation Notes

Installation is typically performed by qualified millwrights or mechanical technicians. De-energize and lock out all power to the equipment before removing the old bearing. Use a proper bearing press or driver tool to seat the replacement bearing squarely in the housing bore — never strike the bearing directly with a hammer. Verify shaft and housing tolerances before pressing to avoid overloading the bearing raceway during installation.
