The Bryant Model 20 Internal Grinder is a fully automatic, high production machine for the precision grinding of internal surfaces. It will handle with equal ease, straight bores, taper bores, and a variety of internal forms. Capable of either shoe centerless or chucking operation, it’s the ideal tool for grinding bushings, gears, sleeves, front wheel drive parts, ball, straight and taper roller bearing components, and similar items.

This unique machine was designed to save space and weight, yet retain the productive capability of much larger grinders. Approximately the size of a 5 foot cube, it does all this while offering greater flexibility. Time-tested Bryant features, combined with advanced design concepts, result in a machine with exceptional versatility.
