Aventics TRR Series Rack And Pinion Pneumatic Cylinders

TRR Rotary Type Cylinders are engineered for precision and flexibility in motion control. Offering an adjustable rotation angle up to 360°, sizes from Ø 32 to 100 mm, and a magnetic piston with a dual piston and rack, they deliver dynamic performance. Featuring pneumatically adjustable cushioning for smooth operation, these cylinders work within a pressure range of 2 to 10 bar and temperatures between -20 to 80 °C. Suited for compressed air uses, they have a maximum particle size tolerance of 5 µm and oil content between 0 to 1 mg/m³, with theoretical torque at 6.3 bar enhancing their efficiency for precise rotary motion control.

Device Function

The AVENTICS™ Series TRR is a sophisticated rotary cylinder, ingeniously designed by integrating two ISO-standard pneumatic cylinders with a rack and pinion gearbox. This configuration allows the device to transform the linear motion generated by the cylinders into powerful rotary motion. It excels in generating high torques, essential for handling heavy-duty industrial applications. Additionally, the device features an adjustable angle of rotation, offering versatility and precise control, making it highly suitable for a variety of tasks where specific rotational adjustments are needed.


To maintain the AVENTICS™ Series TRR rotary cylinder, regularly inspect for wear, ensure parts like the rack and pinion are lubricated, and keep the unit clean. Check alignment and tighten connections, maintain clean, dry air supply for pneumatic operation, replace worn seals and gaskets, and perform functional tests. Always follow the manufacturer’s maintenance recommendations to ensure optimal performance and longevity.
