Precision ball bearings are used for high precision applications in a variety of markets, including aerospace, health, machine tool, robotics and general industry.

MM/MMV (Machine Tool Bearings)
Super precision bearings manufactured to MM/MMV tolerances combine the accuracy and performance of ABEC 9/ISO P2 with the non-critical features of ABEC 7/ISO P4 levels for cost effectiveness.

MMX (Machine Tool Bearings)
Type MMX super precision bearings are made to ABEC 9/ISO P2 levels and have closer tolerances and running accuracies than ABEC 7/ISO P4 tolerances. Ideal for ultra-high speed grinding spindles designed for tight dimensional tolerances and super-fine surface finishes.
