Application Checklist

Engineering Specifications

Repeatability: ± 0.01° (of potentiometer itself)

Nonlinearity: ± 88° (± 0.25% of 340±4°)

Resolution: Infinite

Signal Input: 10 VDC typical

Input Impedance Required: 100 Kohm

Signal Output: 0 to 10 VDC FS (depends on

FS mechanical rotation)

Rated Life of Potentiometer: 10 million cycles

Temperature Coefficient: ± 600 ppm/°C

Electrical Rotation: 340° ±4°

General Specifications

Rotary action of the Pneu-Turn rotary actuator is

achieved through the use of a rack and pinion as-

sembly. Just as with any hydraulic or pneumatic

cylinder, the speed of rotation may be controlled

through the use of flow controls. The PTF may also

be controlled with Bimba's Pneumatic Control Sys-

tem, Model PCS.

Care should be taken to insure that the inertial force

does not exceed the published torque capacity.

Port Positioning

Ports on the PTF may be repositioned to accommo-

date any air line configuration by loosening the three

body retainer screws. Once desired port positions

are obtained, screws must be tightened to specified

torque values in the table below.

Lubrication

The PTF is prelubricated 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 the oil to the actuator every 500

hours of operation. Recommended oils for Buna N

seals are medium to heavy inhibited hydraulic or

general purpose oil.

The rack and pinion gear and ball bearings are pre-

lubricated at the factory for extensive maintenance

free operation. If additional lubrication is 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: 150 psi air or oil with S Option

Rotation Tolerance:

1-1/16" - 2" bore is -0° to +10 °. The Angle Adjust-

ment Option allows 45° of adjustability. If cushions

are ordered in conjunction with the angle adjust-

ment option, adjustability will be 10°.

Temperature Range: Standard Seals: -20° to

200° F; V Option High Temp seals: 0° to 250°.

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 models

have zero mid-rotational and end of rotation back-

lash.

Breakaway: Less than 3 psi.
