Chrome-plated steel bearings cannot withstand temperatures up to 120°C in continuous use. They also cannot be used continuously at temperatures up to 150°C. At temperatures above a certain level, the strength of chrome-plated steel bearings decreases, and their dimensions vary more than stainless steel.

GMW offers miniature ball bearings for Metric and Inch series as below:

  • Flanged miniature ball bearings in Chrome steel
  • Stainless Steel Miniature Bearings for high precision
  • Stainless Steel Miniature Flange Bearings

GMW offers material:

  • SAE52100 / SUJ2 / GCr15 steel or equivalent
  • 440C (alternatively 304 or 420D) stainless steel

GMW offers lubricant solution:

  • High temperature grease up to 150°C with base-oil Lithium
  • High temperature grease up to 200°C with base-oil Polyete perflorua

Tolerances class: Grade P0, P6, P5, P4

Flanged Miniature Bearings in Chrome Steel

Chrome steel bearings can handle temperatures up to 150°C when used continuously, with a steel retainer and proper lubrication. At temperatures above 150°C, the strength of chrome steel bearings decreases.

For detailed specifications in inch and metric series on load capacity and speed ratings, please refer to the technical drawings available by clicking ”More”. While our chrome steel bearings are designed for high load and speed applications, it’s recommended to operate them below their maximum rated values to ensure optimal bearing life.

Stainless Steel Miniature Bearings for high precision

Stainless steel bearings, with a stainless steel retainer and a suitable high-temperature lubricant, enable operation at temperatures ranging from a steady 150°C to intermittent peaks of 200°C.

For comprehensive technical insights into the inch and metric series, click on ‘More’ provided below for detailed technical drawings showcasing load and speed data for the bearings. The load ratings shown are for S440C stainless steel bearings.

Stainless Steel Miniature Flange Bearings

These bearings, with a stainless-steel retainer and a suitable high-temperature lubricant, can be operated at temperatures of 150°C constant or up to 200°C intermittent. At temperatures exceeding these thresholds, the load capacity of the stainless steel may decrease.
