Traditional Barden products are predominantly radial, single row, super precision angular contact (separable and nonseparable) and deep groove ball bearings. Bearings are classified as either instrument or spindle bearings, and are made to exacting ABEC-7 or ABEC-9 specifications, standards which Barden routinely exceeds.

A radial or axial impact to a spindle shaft can cause brinelling, or permanent “denting,” that subsequently will result in rapid deterioration of a spindle’s precision bearings. Spindles should be properly handled and protected from vibration and other potentially adverse influences to help keep the equipment performing as intended.

Bearing tolerances explained | Engineering3
Bearing tolerances are an important concept for design engineers to understand. The American Bearing Manufacturers Association (ABMA) developed the ABEC tolerance standards for bearing manufacturers to follow when producing radial ball bearings.

Bearing Tolerances & Clearances - ISO Bearing Tolerances .
Figure 2 is a graphic representation of the relationship to the various fits with the bearing bore and O.D. tolerances. Shaft fits represented above the bearing bore indicate an interference fit. Housing fits above the bearing O.D. represent a clearance fit, while those below the bearing O.D. represent an interference fit.
