Miniature bearings, also known as small bearings or micro bearings, are designed to operate in applications that require compactness, low friction, and high rotational precision. They are characterised by their small size, often with a bore diameter of less than 30mm, and precise construction. Miniature bearings can be used at high speeds and withstand moderate loads.

Applications: Servo & Miniature Motors, Turbo-Machinery Pumps, Scroll Compressors,Surgical Devices, Medical Handpieces & Instruments, Pulmonary Assist Devices, Aircraft & Spaceflight, Flow Meters, Fuel Controls, Gimbals, Slip Rings.
