SR-171-V is BIMBA’s single-acting spring-return pneumatic cylinder featuring a 1-1/2 in bore and a 1.000 in stroke, designed for compact push–extension action with automatic return when air pressure is released. It uses front nose mounting, a round piston rod, and aluminum end caps with a stainless steel rod, delivering a durable, lightweight package for short-stroke linear actuation. The unit operates without cushioning, bumpers, or a rod wiper, and the piston is non-magnetic. This model is configured as a spring-return cylinder, extending under air pressure and returning to the retracted position via its internal spring; the assembly weighs approximately 0.45 kg.
