623 DKF 3x10x4 deep groove ball bearing

Main description

The 623 DKF deep groove ball bearing with dimensions 3x10x4 mm is a miniature precision bearing designed for applications requiring compact size, low friction and stable high speed operation in small mechanical systems.

A deep groove ball bearing in miniature format is widely used in devices where space is extremely limited but reliable rotational performance is essential. The 623 series belongs to the smallest range within the deep groove ball bearing category, commonly applied in electronics, micro motors and precision instruments.

Thanks to its compact size 3 mm inner diameter, 10 mm outer diameter and 4 mm width, the 623 DKF is ideal for lightweight assemblies where minimal resistance and consistent motion are required. It supports radial loads and light axial loads in both directions, ensuring versatility across different applications.

This bearing is especially suitable for systems where smooth operation, low noise and durability are critical despite the small dimensions.
