Silver metal rotary actuator with cylindrical body and protruding shaft

SPEEDAIRE

SPEEDAIRE Rotary Actuator 180 Deg 50mm Bore

SKU CH-PQMR-7JHXF

Single-vane pneumatic rotary actuator delivers 11.9 N-m torque through 180 degrees at up to 145 psi with a 50 mm bore and 12 mm shaft

  • Product typeVane Style
  • 180° rotation for half-turn automation
  • 9 N·m torque drives heavier loads
  • 50 mm bore fits standard pneumatic circuits
  • Rubber cushions soften end-stop impact
  • Magnetic piston enables position sensing

SPEEDAIRE Rotary Actuator 50mm Bore

The SPEEDAIRE rotary actuator is a single-vane pneumatic device built for 180-degree rotation in automation and machinery. It suits engineers and maintenance teams needing precise angular motion driven by compressed air. The unit arrives new and RoHS compliant for restricted-substance environments.

180-Degree Rotation with 11.9 N-m Torque

The defining specification is the 180-degree rotation angle paired with a maximum output torque of 11.9 N-m at 145 psi. This torque figure determines whether the actuator can move the intended load through the full half-turn stroke. The 50 mm bore and 12 mm shaft diameter define the mechanical interface for mounting.

Capacity Range 21.76 to 145 psi

Operating pressure spans from a minimum of 21.76 psi up to 145 psi, giving a usable window for speed and force control. The rubber cushion and magnetic piston provide end-of-stroke damping and position sensing within that range. Ambient temperatures from 41 to 140 degrees Fahrenheit set the thermal limits; the actuator runs out of capacity beyond these pressures or temperatures.

Questions about this item

What does the 11.9 N-m torque rating mean when the actuator is installed?

At the maximum 145 psi supply the vane delivers up to 11.9 N-m of rotational force through the 12 mm shaft, enabling it to drive loads within that torque envelope.

How does the 1/8 in BSPT inlet limit air flow in practice?

The 1/8 in BSPT port sets the maximum flow capacity; exceeding the 145 psi pressure rating or using undersized tubing will restrict actuation speed.

What mounting space does the 50 mm bore and 39.5 mm shaft length require?

The 50 mm bore body needs a matching bore hole, while the 39.5 mm shaft projection demands at least that clearance beyond the mounting face for full 180 degree rotation.
