Precision Steel Ball Bushing Bearings
  • Bearings provide up to 8 times the bearing service life of high-friction plain bearings, greatly reducing cycle and downtime. Bearing design compensates for torsional misalignment caused by machine deflection or inaccuracies in carriage or base machining. Accurate and compact instrument-rated bearings are excellent for small mechanisms that require high repeatability and responsiveness.
  • Steady-state speeds to 10 fps.; acceleration to 450 fps2 (except instrument-rated bearings) Max. temp.: 500 for steel, 600 F for stainless steel Coefficient of friction as low as 0.001
