Timken® Ball Screw Support Bearings

Designed to support ball screw assemblies under high axial and radial loads, Timken ball screw support bearings minimize axial play and backlash while maintaining smooth, accurate positioning for milling, turning, and grinding applications. Manufactured with precision tolerances and premium materials, these bearings deliver reduced vibration, extended service life, and consistent performance—helping OEMs and machine builders improve throughput, part quality, and overall equipment uptime.

Benefits

Key Applications

  • Materials include clean steel for longer service life.
  • Incorporates tighter preload tolerances for chatter-free cutting and tighter width tolerances for easy fit without regrinding end caps.
  • Innovative cage design permits additional balls for higher load capacity.
  • Features ABEC 9/ISO P2 axial running tolerances to deliver maximum accuracy for precise tool positioning and repeatability.
  • Double-row series has integral, low-torque contact seals to exclude contaminants for reliable operation and extended service life.
  • Available in flanged (MMF) and nonflanged (MMN) series, simplifying installation for both standard and rotating nut mountings.
