The Bimba NRM-313.5-R Non-Rotating Square Rod Pneumatic Air Cylinder is an Original Line actuator with a 2 in bore and a 3.5 in stroke, configured as reverse-acting with a nose-mount. Its square piston rod design—rounded corners to reduce wear—prevents piston rod rotation, a defining feature of Bimba’s Non-Rotating line. A 303 stainless steel rod is standard on Original Line NR cylinders, combining durability with low-friction operation.
