BALL BEARING

Stainless Steel 1.4401 and 14401

This material is used for ball bearings made of plastic. These stainless steel balls are not hardened. They exceptionally resist corrosion and also resist saltwater and alkalis. Hardened steel balls must not be used for plastic ball bearings. The limits of the material in the plastic ring limit the maximum permissible load for the plastic ball bearings. Stainless steel balls are cheaper than glass balls.

Soda-Lime Glass

When a metal free ball bearing is needed, this is when glass balls come into play. Glass balls are also used when the ball bearings’ chemical resistance is high. Soda-lime glass is used to make bottles, flat glass, drinking glasses, and ball bearing material. The chemical properties of soda-lime glass are very good and suitable for ball bearings usually exposed to chemical stress for a short time, but not to great chemical stress. The name lemon glass has also been given to it because of its light green color.
