SB Series Spring-Set Brakes (Power-off)

SB Series Spring-Set Brakes (Power-off)

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.
