Single direction miniature thrust ball bearings for shaft sizes from 3mm to 10mm.
Miniature thrust bearings or axial bearings with grooved washers can take thrust loads in one direction only and are available with bore sizes as small as 3mm. Miniature thrust bearings are normally supplied from stock in the UK with chrome steel washers and brass or stainless steel retainers. They can also be manufactured fully in stainless steel but this is usually special production and may be subject to a minimum quantity.
Miniature thrust ball bearings can withstand axial or thrust loads only. These miniature thrust bearings have washers incorporating a groove or raceway. They have higher load and speed ratings than the flat washer type. They also 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.
