SB Series High Performance Spring-Set Brakes
Our SB Series is designed as a servo brake with low backlash splines for high performance applications. The spline drive construction withstands high impact stresses imparted by typical servo systems. High temperature operation is available with Class H case assemblies containing long live brake linings (non-asbestos) and TFE coated leads. With low inertia rotating components, high rates of acceleration are obtainable.
