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 ensure that the inertial force does not exceed the published torque capacity. An 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 Ball Bearing option, axial loads can be applied in either direction. The Angle Adjustment 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. LUBRICATION The Pneu-Turn Rotary Actuator 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 introduction of oil to the actuator every 500 hours of operation. Recommended oils for Buna 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 LOCATION The standard position of the woodruff key is 12 o'clock at the center of rotation. RATINGS: Pressure Rating: All Bimba Pneu-Turn Rotary Actuators are rated for 150 PSI air. Rotation Tolerance: Standard rotation tolerance is -0+10. Temperature Range: Buna N: (Standard) -20F to +200F; Option (V) High Temperature seals: 0F to +400F. Temperature range of high temperature seals with Ball Bearing option is 0F to +250F. If cylinders are operated at temperatures below 0 for extended time periods, special modifications may be required. Special seal materials are available on request. Backlash: Without "X" option 1-1/2 of Arc 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. Double rack models have zero mid-rotational backlash. Breakaway: less than 5 PSI.
