Bimba NRM-311 Non-Rotating Pneumatic Cylinder

The Bimba NRM-311 Non-Rotating Pneumatic Cylinder is a compact, orientation-stable actuator designed for precise linear motion in automation. It features a 2-inch bore and a 1-inch stroke in a three-position, non-rotating configuration that keeps tooling aligned through extended, retracted, and central positions. As part of Bimba's Original Line, the cylinder uses a square-profile piston rod to prevent rotation and a stainless steel piston rod as standard components, with urethane rod seals and permanent grease lubrication for low-maintenance operation. A front nose mounting option enables straightforward attachment to fixtures or tooling plates, supporting repeatable end-of-stroke positions and mid-stroke holds without rotating the rod during extension or retraction. The combination of durable construction, fixed orientation, and a compact form factor makes it suitable for indexing, end-of-arm tooling, and other applications where consistent, non-rotating linear actuation is required.
