Miniature Ball Bearings — Small Bearings For Big Requirements

Miniature ball bearings are deep groove ball bearings in small. Their dimensions make them suitable for special applications. In addition, they allow very high speeds with low noise.

Further Information


Miniature bearings are sometimes referred to as instrument bearings or micro bearings. They are used in gyros, anemometers, flow meters, miniature gearboxes, small motors, and radio-controlled models.

TFL Bearings has a huge selection of Miniature Bearings and Instrument Series Ball Bearings with over 500 types available. Precision tolerances from ABEC-1 through ABEC-9 are generally available for most miniature products. Typical bore sizes of miniature ball bearings start at 3 mm with an outside diameter of 10 mm. Custom-made miniature bearings can have borne sizes as small as 1 mm!

Miniature bearings refer to various bearings with a metric series and an outer diameter of less than 9mm. An inch series with an outer diameter of less than 9.525mm! The primary materials are carbon steel, bearing steel, stainless steel, plastic, ceramics, etc. The smallest inner diameter can be 0.6mm, and the inner diameter is generally 1mm. The smallest commercial bearing in the world can achieve this size: 1.5mm outer diameter, 0.5mm inner diameter, and six steel balls with a diameter of 0.25mm. Miniature bearings are as diverse as ordinary bearings. The most common miniature bearings are miniature roller bearings and miniature ball bearings. Miniature bearings are often called mini bearings, micro bearings, or tiny bearings.
