Pneumatic Rotary Actuators

Pneumatic Rotary Actuator – B671/F672 Series (Heavy Duty Rack-And-Pinion)

Parker - Pneumatic Rotary Actuator - B671/F672 Series
The B671 series pneumatic rotary actuator is designed to provide force in a reciprocating, rotational motion. It is ideal for any application requiring constant torque through a rotational distance: rotating or lifting heavy objects, positioning or bending operations. The F672 Series utilizes the same high quality construction found on the B671 Series with the addition of a coupling arrangement for a hydro-check. An F672/hydro-check assembly will provide controlled feed rates and excellent rotational control with pneumatic power through adjustable hydraulic resistance.

The B671/F672 series pneumatic rotary actuator can be powered by shop air or inert gas. The actuators are pre-lubricated at assembly with NLG1 grade 2 grease with outstanding oxidation stability and corrosion resistant additives. This pre-lubrication is intended for use in pneumatic systems where airline lubrication is not used. However, to assure maximum service life of the cylinder, the air supply should be properly filtered and moisture free. The pneumatic rotary actuator can be controlled by any conventional 4-way valve – hand, foot, mechanically or electrically controlled. All four sizes of rotary actuators are designed for direct on-shaft installation – no flexible couplings, cam and roller or chain and sprocket combinations are required.

The rotary actuator/hydro-check combination consists of the F672 series actuator axially linked to an F172-2 or F172-3 series hydro-check. The hydro-check is a precision built adjustable hydraulic resistance unit designed to provide controlled feed rates. When coupled to an actuator, excellent rotational control is attained. The rotary actuator/hydro-check combination provides consistent torque with adjustable hydraulic resistance for a smooth controlled rotational feed rate. Axial couplings of these units eliminate eccentric loading of component parts. These actuators are available in three torque ranges to comply with varying load requirements. The hydro-check is capable of checking axial loads to 3,000 lbs. and is available with many controlling options.

Hydraulic Rotary Actuator – HTR Series (Medium Duty)

Parker - Hydraulic Rotary Actuator - HTR Series
The HTR Series rotary actuator incorporates many hydraulic and mechanical features that make this actuator both robust and ideal for the most demanding high production applications. These features include: high load capability tapered roller bearings; a chrome alloy steel rack and pinion gear set; a high strength ductile iron or steel housing; and proven Parker Hannifin cylinder components. The HTR Series actuators have been successfully employed in automotive plant production machinery; machine tool equipment; plastics and rubber processing machinery; basic metals production machinery and in material handling machinery.

The HTR Series can be employed as an integral machine component, where the actuator can simultaneously transmit torque and support the line shaft or the load. Such an arrangement allows for the elimination of one set of external support bearings. Optional cushions can also be incorporated to decelerate external loads, thus eliminating the need for an external deceleration device such as shock absorbers or brakes. Additionally, machine installations can be simplified with the hollow shaft feature by eliminating additional coupling. This is achieved by means of a square shaft key or if needed the housing can be drilled and tapped to mount various brackets. For easy serviceability, the piston seals can be inspected and replaced while the actuator remains installed on the machinery.
