This center from Riten Industries is capable of adjusting the load on the workpiece. Utilizing Bellville washers, it automatically compensates for thermal expansion. Three color-coded rings illustrate the pounds of axial force that is being applied. This is beneficial when the tailstock on the lathe or grinder cannot display the required clamping pressure for accurate machining. 

 

The center is offered in 3 to 6 Morse taper, in standard and tracer point. Maximum axial loads range from 1,150 to 5,600 lbs. RPM up to 4000, and weight of workpiece up to 7600 lbs. Accuracy guaranteed to ± .0001.
