2 imba Pneu-Turn Rotary ctuators The model number of Pneu-Turn Rotary ctuators consists of three alphanumeric clusters. These designate product type, series, angle of rotation and special options. Please refer to the charts below for an How to Order PT DV Metric example of model number PT DV. This is a 27mm bore, single rack, 90 angle of rotation actuator with angle adjustment on both sides, dual shaft and high temperature option. SERIES TORQUE FCTOR mm ore, Single Rack mm ore, Double Rack mm ore, Single Rack mm ore, Double Rack mm ore, Single Rack mm ore, Double Rack mm ore, Single Rack mm ore, Double Rack mm ore, Single Rack mm ore, Double Rack Single Rack see page 4.3. Double Rack see page 4.5. To determine theoretical output torque (N-m), place a decimal point between the first and second digits of the series number. Then multiply that number by the air line pressure (ars) for the approximate torque produced. For example, a PT will produce an output torque of 0.60 times the air line pressure. t 6 ars this torque will be 3.6 N-m. NGLE OF ROTTION bove angles are standard. Other angles available upon request. Rotation angles up to 1080 are available. See page 4.10 for rotational tolerance.

10 imba Pneu-Turn Rotary ctuators Metric CTUTOR OPERTION Rotary action of the Pneu-Turn Rotary ctuator is achieved through the use of a rack and pinion assembly. Just as with a pneumatic or hydraulic cylinder, the speed of rotation may be controlled through the use of flow controls. The action at the end of the rotation can be controlled by the use of adjustable cushions, which are available as an option. Care should be taken to insure that the inertial force does not exceed the published torque capacity. n external stop may be necessary to avoid exceeding the torque capacity due to inertial loads. When mounting the Pneu-Turn against the shaft side of the housing, be sure to provide clearance for the pilot diameter to avoid excessive bearing pressure. For standard models, axial loads must only be applied in the direction indicated on the dimensional drawings. The Dual Shaft or Rear Shaft options can be used to correctly orient tension induced axial loads. With the all earing option, axial loads can be applied in either direction. The ngle djustment Option will allow 45 of adjustability. If cushions are ordered in conjunction with the angle adjustment option, adjustability will be 10. PORT POSITIONING Ports on the Pneu-Turn may be repositioned to accommodate any air line configuration by loosening the three body retainer screws. Once desired port positions are obtained, tighten screws to specified torque values. LURICTION The Pneu-Turn Rotary ctuator is pre-lubricated at the factory for extensive, maintenance-free operation. The life of the rotary actuator can be lengthened by providing additional lubrication with an air line mist lubricator or direct Standard Line Series Series Specifications 4.10 introduction of oil to the actuator every 500 hours of operation. Recommended oils for una N seals are medium to heavy inhibited hydraulic and general purpose oil. If High temperature seals, use Dow Corning #710. Other types of prelube are available upon request. The rack and pinion gear and ball bearings are prelubricated at the factory for extensive, maintenance-free operation. If additional lubrication should be required, use a high grade bearing grease. WOODRUFF KEY LOCTION The standard position of the woodruff key is 12 o clock at the center of rotation. RTINGS: Pressure Rating: ll imba Pneu-Turn Rotary ctuators are rated for bar air. Rotation Tolerance: Standard rotation tolerance for 14mm- 27mm is and for 38mm-50mm bore is 0 O to 10 O. Temperature Range: una N: (Standard) -25 C to +95 C; Option (V) High temperature seals: -18 C to +205 C. Temperature range of high temperature seals with all earing option is -18 C to +120 C. If cylinders are operated at temperatures below 0 for extended time periods, special modifications may be required. Special seal materials are available on request. acklash: Without X option, 1-1/2 O of rc Maximum, Double rack actuators have zero backlash at end of rotational stroke With X option, single rack models have zero mid rotational and end of rotation backlash.

11 Metric imba Pneu-Turn Rotary ctuators Kinetic Energy Capacity load connected to the shaft of a Pneu-Turn will produce kinetic energy as it is rotated. This kinetic energy must be absorbed by the Pneu-Turn or other stopping device. If the Pneu-Turn is to stop the load without external devices, then the application kinetic energy must not exceed the maximums noted in the table below.
