Miniature Ball Bearings

Miniature bearings are offered in metric and inch sizes in open type, with seals or shields, flanged or unflanged. They are available in stainless steel and chrome, and in the case of grew can also be manufactured in ceramic or a hybrid material known as sv material. This material is beneficial in a highly corrosive environment. Show details

FREQUENTLY ASKED QUESTIONS

Can miniature ball bearings be used effectively in both radial and thrust load applications?

Yes, miniature ball bearings, like those offered by PIB Sales, are designed to be effective in handling both radial and thrust load applications. Despite their small size, these bearings are engineered to support axial (thrust) loads in both directions as well as radial loads. This versatility makes them suitable for a variety of precision applications where space is limited but load handling is essential.

What is the difference between 608 and 608ZZ bearings?

The difference between 608 and 608ZZ bearing is the ZZ designation is for shields. The 608ZZ shields provide protection from contaminants and help retain lubrication. The shields are on both sides of the bearing, a single shield or no shields are also an option. The standard 608 2RS bearing typically has two rubber seals.

Why choose NMB miniature ball bearings for precision instruments?
