SAJRAJ self centering steady rest work on an entirely different principle. Three rollers hold the work piece at point approx 120o apart. These rollers move such that they always inscribe concentric circles between them. This feature along with the internal compensating system prevents the dislocation of work piece center under changing clamping pressure. This results in high centering accuracy By mounting accordingly these steady rests can be used for turning outside diameters, inside diameters, facing, drilling, grinding, induction hardening etc.
