miniature and instrument ball bearings

Miniature bearings are sometimes referred to as instrument bearings or micro bearings and are used in applications as varied as gyros anemometers flow meters miniature gearboxes small motors and radio controlled models Our chrome steel miniature bearings are also available with a flange on the outer ring as shown in Products Variants below Miniature A wide variety of bearing types and design variations are available to meet the requirements of virtually all precision instrument applications Bearing types include radial retainer pivot thrust high speed radial angular contact and full ball complement Many selections also are available in both inch and metric dimensions

Mounting and Fitting Miniature Ball Bearings

Miniature bearings can have very thin inner and outer ring cross-sections ( 008 in some cases) When such a bearing is pressed onto a shaft or into a housing depending on the material up to 80% of the interference fit translates into loss of radial play in the bearing

How-To Guide: Proper Lubrication of Miniature Instrument Ball Bearings Bearing lubrication is an essential element of bearing selection Proper lubricant can reduce friction prevent bearing wear protect bearing surfaces from corrosion and carry away excess heat from bearing operation
