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

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.

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.

Type HX delivers excellent running accuracy and are manufactured to precise ABEC9 (ISO P2) levels for runout tolerances.

Ceramic hybrid angular contact ball bearings combine steel rings with ceramic rolling elements to deliver higher spindle speeds and increased dynamic radial stiffness.

Ball screw support bearings are available in single- and double-row configurations and are widely used in motion control applications.

Miniature and instrument bearings are used in medical and industrial handpieces and other precision applications. Ball bearing designs include radial, angular contact, thrust and pivot.

Thin section bearings are available in radial, angular contact and fractured race designs and are used in precision applications such as gimbals, rotary joints and robotics.
