Overview
The PHD CRS6U 20X40-BB-M pneumatic cylinder is a compact, double-acting actuator engineered for reliable linear motion in space-constrained applications. With a 20mm bore diameter and 40mm stroke length, this cylinder delivers consistent performance in assembly automation, packaging equipment, material handling, and production machinery. The base-mount (BB) configuration ensures stable installation on flat surfaces, while the -M option (magnetized) integrates compatibility with proximity sensors.
Key Features
- Compact profile design minimizes footprint in confined spaces
- Double-acting operation for both extend and retract power
- Base-mount (BB) bracket configuration for direct mounting on equipment frames
- Magnetized (-M) rod end enables non-contact proximity switch integration
- ISO 6432 compliant design for global standardization
- Rated for 70 million linear inches minimum operating life at standard pressures

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The CRS6U 20X40-BB-M configuration (20mm bore, 40mm stroke, base mount, magnetized) is specific to this part number. Similar bore and stroke combinations in different mounting styles (e.g., CRS6U 20X40-FB, CRS6U 20X40-HB) are not direct replacements.
Works With
- PHD pneumatic sizing and selection tools (www.phdinc.com/apps/sizing)
- Standard 80 psi [5.5 bar] compressed air supply systems
- Inductive proximity sensors (via magnetized rod option)
- Manual directional control valves and solenoid valve systems
- Pneumatic tubing and quick-disconnect fittings (1/8″ and 3/16″ ID hose compatible)
