The smallest linear ball bearing in the world

MPS Microsystems has extended its product range of miniature ball screws, linear ball bearings, and electromechanical microsystems with the smallest linear ball bearing in the world.

With an inner diameter of 1.5 mm and outer diameter of 3.0 mm, it is fitted with four rows of 20 balls each (0.3 mm in diameter) for a total length of 4 mm. The "Grade 3" balls - the highest quality defined by the ISO 3290/DIN 5401 Standard - and high-precision execution of the cage and housing reduce friction and eliminate the stick-slip effect.

Special executions with biocompatible materials can also be developed upon request.
