Rotary actuators
Pneumatic cylinders and drives
Aventics rotary actuators comprise the TRR series rack-and-pinion drives in double-acting construction with bores from 32 to 100 mm and swivel angles of 90, 180 and 360 degrees. The rack-and-pinion mechanism converts the linear piston movement into a precise rotary motion. Part numbers TRR-DA-[bore]-[angle] and TRR-DA-[bore]-[angle]-AD (with adjustable cushioning) encode bore and swivel angle directly.
Rack-and-pinion drive - precise conversion of linear movement into a defined swivel motion
Swivel angles 90 / 180 / 360 degrees - three standard angles for turning, tilting and full rotation
Bores 32-100 mm - covers TRR-DA-032 to TRR-DA-100, for different torque ranges
AD variants (adjustable damping) - hydraulic end-position cushioning for soft deceleration under load
87 variants - bore 32/40/50/63/80/100 mm, angles 90/180/360 degrees, standard and AD
| Bore (mm) | Swivel angle | Variants |
|---|---|---|
| 32 | 90 / 180 / 360 degrees | Standard |
| 40 | 90 / 180 / 360 degrees | Standard |
| 50 | 90 / 180 / 360 degrees | Standard + AD (adjustable cushioning) |
| 63 | 90 / 180 / 360 degrees | Standard + AD |
| 80 | 90 / 180 / 360 degrees | Standard + AD |
| 100 | 90 / 180 / 360 degrees | Standard + AD |
Typical applications: Swivel and turning units in assembly automation, tilting fixtures for workpieces in metalworking, turntables and rotary transfer in packaging machines, shut-off and control damper drives in process engineering, and pneumatic gripper pivot axes in handling robot cells.
