Bimba 125-RP Pneumatic Cylinder

The Bimba SR-125-RP Pneumatic Cylinder is a compact, rear-pivot, single-acting actuator designed for space-constrained installations requiring a spring-return, reverse single-acting operation. With a 1-1/4 in bore and a 5.000 in stroke, the cylinder provides a controlled extend/retract cycle driven by air pressure in one direction and a return provided by an internal spring, the designation 'Reverse Single Acting - Spring Extend' clarifying its actuation method. It mounts via a Rear Pivot, enabling linkage or articulated connections where straight-line motion must translate through a pivot point. A standard bumper cushions the rod at end-of-stroke, and the unit ships without a magnetic piston or rod wiper, aligning with its basic, rugged design for basic automation tasks. The SR-125-RP is suitable for applications that require compact actuation with predictable stroke length and simple installation, such as fixture operations, positioning tasks, or end-of-arm tooling where a spring-return single-acting cylinder fits the mechanical envelope.
