Small thrust ball bearings (or axial bearings) are available with bore sizes as small as 2mm. Mini ball 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 axial bearings with either flat races 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.
Quality by Science
We employ statistical methods to our processes in order to assure our customers that we will deliver consistent quality. We monitor our key bearing characteristics by Statistical Process Control and achieve Cpk levels above the standard.
Predictability
It is more than luck that our quality record is flawless. Using mathematical distribution and probabilities, our performance can be predicted and is done as a regular part of our PPAP (Production Part Approval Process).
