Miniature Bearings

Miniature Bearings

A miniature bearing simply refers to the smallest size of ball bearings available. Measuring the outer diameter, this usually means 20mm or smaller in metric or 1 inch or smaller in imperial. Ashley Power Limited can supply miniature ball bearings as small as 1mm, or .1181 inches on the inner diameter. Miniature bearings are ideal for precision work and applications that require a lot of functional mechanical parts in a small space.

Miniature ball bearings are designed to handle loads and reduce friction so that those loads are moved easily through the application.

Ashley Power is able to supply miniature bearings plain or flanged. These bearings can also come sealed (2RS), shielded (ZZ) or open in which the seals and shields are used to protect against leaks and contamination.

Ashley Power Limited can supply miniature bearings in carbon chrome or stainless steel.

Stainless steel bearings are corrosion resistant and are perfect for handheld medical and dental equipment. Miniature bearings can also be found in clocks and watches, model cars, and many other applications.
