SMC NRB056-045 Pneumatic Shock Absorber

The SMC NRB056-045 Pneumatic Shock Absorber is a compact, non-adjustable damper in the NRB family designed to decelerate moving loads smoothly in automation and end-of-travel applications. It features a 0.45-inch stroke and an outer diameter of about 0.56 inches, with an overall length of 3.100 inches and a weight near 0.13 lb. The NRB series uses a fixed orifice to provide consistent deceleration without adjustment, accommodating varying speeds and loads. This basic cushion model (NRB056-045) tolerates collision speeds up to 16 ft/s and delivers a compressed spring force of 3.59 lb and an extended force of 1.54 lb, with energy absorption per cycle up to 170 in-lbs and a maximum absorption frequency of 45 cycles per minute. NRB shocks are available in six sizes, making NRB056-045 a precise fit for small linear actuators and compact equipment where reliable, maintenance-free damping is required.
