Pneu-Turn Rotary ActuatorThe rotary action of the Pneu-Turn Rotary Actuator 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. 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 pre-lube 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 standards 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) -20°F to +200°F; Option (V) High Temperature seals: 0°F to +400°F. Temperature range of high temperature seals with Ball Bearing option is 0°F to +250°F. 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: 1-1/2° of Arc Maximum; Double rack actuators have zero backlash at end of rotational stroke. Breakaway: Less than 5 PSI. The interior features and advantages include:

Pneu-Turn® Position Feedback Rotary ActuatorThe Pneu-Turn® position feedback rotary actuator (PTF) provides continuous shaft position sensing. Standard features include shaft ball bearings and the elimination of mid-rotational backlash. Use the Bimba PTF in conjunction with Bimba's Pneumatic Control System (PCS) to achieve rotary shaft positioning accuracy within ±0.5°. Rotary action 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.

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 or oil with S option. Rotation Tolerance: Standard rotation tolerance is -0° + 10°. The Angle Adjustment Option allows 45° of adjustability. If cushions are ordered in conjunction with the angle adjustment option, adjustability will be 10°. Temperature Range: Buna N: (Standard) -20°F to +200°F; Option (V) High Temperature seals: 0°F to +250°F. Note: If used for positioning applications, it is recommended to use low temperature lubricant for temperatures less than 35°F. Backlash: Both single and double rack actuators have zero mid-rotational and end of rotational stroke backlash. Breakaway: Less than 3 PSI. Pneu-Turn PCS Specifications and Options |
