Overview
The Bimba NRM-040.5-D is a compact, double-acting non-rotating pneumatic cylinder engineered for precision motion control in manufacturing and industrial automation applications. As part of Bimba’s Original Line non-rotating series, this cylinder combines proven design with enhanced durability and minimal maintenance requirements.
Key Features
- Non-rotating design: Square piston rod prevents rotation with superior rotational control via unique geometry with rounded corners
- Double-acting operation: Pressurized air drives both extend and retract strokes
- Permanent grease lubrication: Features permanent grease lubrication for extended service life without additional maintenance
- Proven reliability: Design enhancements more than double the anticipated service life
- Front nose mounting for flexible installation options
- Stainless steel piston rod standard for corrosion resistance
