PNEUMATIC-MECHANICAL CENTERING SHAFT – Series 1220-LF or 1220-LG
Extremely high performance shaft with air-activated internal piston(s) that mechanically drives ramped expanders outward. Air is introduced into one port to inflate, and into another port to deflate. Always custom made, the shaft is available in lift-out or cantilevered design, with either expanding leaves (Model 1220-LF) or lugs (Model 1220-LG).
* Absolute roll centering with the ease of pneumatic operation
* Positive expansion and retraction to a consistent diameter
* High speed, weight, and torque applications
* Low maintenance
* Models 1220-LFS and 1220-LGS available with either Air inflate/Springs-to-retract or Safety Design Springs-to expand/Air deflate.
USAGE: Recommended for your most severe unwinding or rewinding
applications, especially for extremely high weights, tension, and speed, in metallizing applications, or wherever perfect centering is required.
