The R Series Actuatoris a heavy-duty rack and pinion style rotary actuator that is designed to excel in the most rigid applications. The R Series includes a high torque-to-size ratio as well as accurate positioning.

Numatics R Series Standard Specifications Include:

• Bore sizes from 1” through 3-1/4”
• Nominal pressure rating is 150 psi air
• Standard rotations are: 45°, 90°, 180°, 270°, and 360°
• Minimum breakaway pressure: 5 psi non-cushioned, 10 psi cushioned
• Standard temperature -10°F to 165°F (-23°C to 74°C)
• NPTF ports
• Flexible port locating

Numatics R Series Features Include:

• The rack and pinion is made from high strength alloy steel and is induction hardened for long life.
• The ball bearings are sealed and pre-lubed in an effort to prevent contamination from negatively affecting the operation.
• The rack bushing is made from bearing bronze and is durable enough to support nearly the full length of the rack.
• The profile tube is hard coat anodized. The hard coating is an electrochemical process, which produces a very dense surface of aluminum oxide.
• The end caps are accurately machined from (6061-T6) solid aluminum bar stock.
  The solid aluminum alloy piston is strong and durable. A magnet groove is standard allowing for easy field conversation.
• The piston seal is a carboxylated nitrile with Teflon® compound for self-lubricating. The U-cup type seal construction is proven and durable.
• The wear band is a stable, lubricating strip located on the piston.
  A 1/4-28 tapped hole (which is plugged) is provided for future installation of an optional grease fitting. The unit is pre-lubed.
• Rotation adjusting knobs, cushions, bumpers and hydraulic shock absorbers can all be added.
