634 2RS 4x16x5 Metric Ball Bearings

634 2RS bearing consists of four main parts: the large ring (outer ring), the small ring (inner ring), the balls (steel balls) between the rings, and the cage that prevents the balls from hitting each other.

Rubber seals on the ball bearings keep out dust etc. This also helps preserve the lubricant. These deep groove ball bearings are versatile, durable and relatively easy to maintain.

These bearings are often found in power tools, skateboards, roller skates, and remote-controlled hobby toys, including toy cars, boats, and airplanes.
