The HTR Series has many features ideal for the most demanding high production applications. The HTR Series can be utilized as an integral machine component, where the actuator simultaneously transmits torque and supports the line shaft or the load. 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.
