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

Our miniature and instrument bearings of both the metric and inch configurations meet the tolerances of ABMA Standard 20 for ABEC 1 metric series bearings. Stainless steel or chrome steel bearings are available with crown or ribbon type metallic cages. Open or shielded bearings may be flanged or unflanged. Various types of seals may be specified depending upon the anticipated environment to which the bearings will be exposed.
