Inner Race Spacers

Inner race spacers are used in drive assembly applications and are designed to make the location of components easy, as well as serving to isolate the ball bearing’s moving parts from its adjacent components. Inner race spacers are placed into the inner race to add clearance for the outer race and its cage. Inner race spacers are available in a wide range of sizes and styles. Typical metric bores are 3mm, 4mm, 6mm and up to 10mm, but others are available. Multiple thicknesses of inner race spacers are available and they can be stacked of required. With excellent accuracy, and a maximum tolerance of up to 0.050 (+ or -) as a general guide, inner race spacers are vital components in drive assembly applications.
