Ball bearings are machinery components, which comprise an outer ring, inner ring, balls, retainers, shields and snap rings. Miniature bearings and small-sized ball bearings have up to 30mm in external diameter. Essential to high-precision rotary components, ball bearings determine rotational accuracy.
Bearing types include Radial Ball Bearings (Deep Groove and Angular Contact) and Thrust Ball Bearings. Radial bearings are designed to carry both radial and axial (thrust) loads, while thrust bearings are designed for pure thrust loads only. Many different configurations are available for ball bearings.
Miniature Bearings
Our miniature bearings range in sizes from .1181 to 1.000 inch O.D. (3mm to 26mm), and are available in inch and metric sizes.
Miniature bearings and instrument bearings are single row 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 both stainless steel for those applications requiring corrosion resistance and chrome for maximum fatigue life.
Minebea manufactures more than 8,500 different types of miniature and small-sized bearings, most of which have external diameters of 22mm or less.
