Miniature Thrust Bearings
Metric series for shaft sizes from 3mm to 10mm
Chrome steel/brass (stainless steel made to order)

  
Miniature thrust bearings (or axial bearings) are available with bore sizes as small as 3mm. Miniature thrust bearings are normally supplied in SAE52100 chrome steel with brass retainers but can also be manufactured in stainless steel (possibly subject to minimum requirements). Miniature thrust bearings can withstand axial or thrust loads only. There are separate types of miniature thrust bearing with either flat washers or washers incorporating a groove or raceway for heavier loads. The grooved type have one washer with a slightly larger bore to allow it to locate in the housing while the other washer has a smaller OD to locate on the shaft.
