Request Information
Specialy ground sprockets are recommended for use with all Torque Limiters. Both faces of Dalton OSD sprockets are ground to approximately a 32 micro-inch finish. Uniform surfaces and parallel faces insure that Dalton OSD's will maintain proper torque release and re-engagement much longer than units without special sprockets. In addition, fibers last longer and OSD's require less maintenance.
