Overview
The Festo FENG-40-160-KF (Part No. 34501) is a precision guide unit engineered for standards-based ISO cylinders. This accessory mount protects cylinders from unwanted torsion while delivering repeatable, accurate stroke guidance under dynamic and static loads. With a 40 mm piston diameter and 160 mm fixed stroke, it is ideal for compact installations requiring high-precision linear motion with lateral load capacity.
Key Features
- Recirculating ball bearing guide for smooth, low-friction stroke guidance
- Torsion protection for ISO standard cylinders (DNC, DSBC, DSBG series)
- Fixed 160 mm stroke design with 40 mm bore compatibility
- Arbitrary installation position allows flexible mounting orientation
- Service life load-dependent; payload and torque ratings available per datasheet
