Heavy-Duty Backstop Clutch TIANIU DSN
DSN (NJD) are Tianiu heavy-duty low-speed backstops built to company standard Q/ZJK2-2004 for shafts with high reaction torque. 13 sizes: rated backstop torque 25,000–1,700,000 N·m, maximum bore 160–620 mm, inner race speed 50–130 rpm, drag torque 32–420 N·m. The backstop is mounted on a parallel key to GB/T 1095-1979 with clearance to the inner race; taper or sliding keys are not allowed as they deform the race. The reaction torque is transmitted through an 800–2,500 mm torque arm to a stop block designed for shear.
