Applications
Miniature ball bearings in the 1/4" bore size are widely used in RC vehicles, small electric motors, 3D printers, robotics, hobby servos, small fans, optical equipment, and light industrial machinery wherever low-friction rotational support is needed in a compact form. The single-shielded design protects one face from debris while leaving the other side accessible for lubrication — a common configuration for applications where occasional re-lubrication is practical. This size is a long-standing standard in precision hobby and light engineering work and remains in common use today across consumer, educational, and light industrial settings.
This pair of steel miniature ball bearings (1/4" x 1/2" x 1/8", single shielded) is in good used condition. Both bearings have been inspected and show normal wear consistent with prior use. The steel races and ball cage appear intact with no visible damage. As with any used bearing, clean and lubricate before putting into service. Sold as a pair of two bearings.

Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
