Miniature Bearings

Miniature bearings are often referred to as instrument bearings. The construction of these miniature bearings enables them to carry moderate radial and thrust loads at low operating torque while providing high performance within a small envelope design. Miniature bearings and instrument bearings are typically available in carbon steel for standard applications, stainless steel for those applications requiring corrosion resistance and in chrome for maximum fatigue life.

Miniature bearings are available in bore sizes ranging from 1mm and are utilized in thousands of applications, such as radio controls, watches, fishing reels, instrumentation, and any other small application where minimization of friction of small rotating parts is important. Miniature bearings are normally available in either ball bearings for applications requiring high speed or needle roller bearings for those applications requiring more load carrying capacity.

Bearing Service stocks many common miniature bearings and has numerous sources to locate the miniature bearings for your particular application. Bearing Service often can offer large savings over purchasing miniature bearings from the OEM of the equipment.
