Bimba Manufacturing Company 121-RP Pneumatic Cylinder

Bimba 121-RP Pneumatic Cylinder is a compact air actuator designed for space‑constrained automation tasks, delivering a 1-1/4 in bore and a 1.000 in stroke in a reverse single‑acting, spring‑extend configuration. It uses a round rod and is mounted with a rear pivot, featuring aluminum end caps and threaded rod for secure attachment. The unit includes standard bumpers and does not incorporate a magnetic piston or rod wiper, with ports not rotated 90° and no additional cushioning or seals beyond the basic configuration. This configuration—spring return in a compact footprint—makes it suitable for short‑stroke actuation in tight assemblies, fixture clamping, or small positioning tasks where a simple, reliable pneumatic return is required. For proper installation, verify mounting clearance and port sizing in your system and ensure you have compatible fittings ready for your specific setup.
