PNEUMATIC CYLINDERS CRR SERIES

Product catalog summary

Pneumatic Cylinders - CRR Series Overview

The CRR Series pneumatic cylinders are rotary actuators that convert linear motion into rotational motion using a pinion-rack coupling. These cylinders are available in a magnetic version, which includes a magnetic piston for signal acquisition via reed contacts. The series offers seven bore sizes ranging from 32 mm to 125 mm and is available with ATEX certification.

Specifications

Bore Sizes: 32 mm, 40 mm, 50 mm, 63 mm, 80 mm, 100 mm, 125 mm
Standard Rotation Angles: 96°, 186°, 366°
Air Entry: Gas sizes 1/8", 1/4", 3/8", 1/2"; positioned at the top with three additional positions at 90°
Maximum Pressure: 12 bar
Temperature Range: -20°C to +80°C
Stroke for 10° Rotation: Varies by bore size (e.g., 2.6 mm for 32 mm bore)
Angle Adjustments: Rotation adjustment "Y" and deceleration "Z" angles provided
Weight: Varies by bore size and rotation angle

Technical Features

End Caps: Made from aluminum light alloy die-cast with black anodization
Central Body: Aluminum light alloy with self-lubricant bronze slide for the piston-rack
Piston and Rack: Made from steel C45
Rotating Group: Mounted on ball bearings for optimal sliding and increased lifespan

Performance Diagrams

Diagrams for torque moment and compressed air consumption are provided to illustrate performance metrics.

Dimensions

Detailed dimensions are provided for each bore size, including calculations for the "A" dimension based on the rotation angle (ALFA).

Catalog excerpts

PNEUMATIC CYLINDERS CRR SERIES The rotary actuator is a unit that converts the linear motion of a cylinder into a rotative motion, with rotation angle presetted by means of a pinion-rack coupling. The range is available also in the magnetic version, that includes the magnetic piston to get the signals by reed contacts. The standard range is of 7 bores from 32 to 125 mm. Available with ATEX certification.
