Rotary Actuator, Rack and Pinion, Rotation Angle (Deg.) 0 to 180, Torque (In.-Lbs.) 2.36 in-lb/psi, Bore 2 In., Cushion Type N/A, Port Size 1/4 in. NPT, Maximum Pressure 150 PSI, Operating Temp. Range -20 to 180 Degrees F, Shaft Type Alloy Steel, Shaft Length 1-7/8 In, Shaft Dia. 1-1/8 In, Keyway Length 1-1/2 In, Housing Material Aluminum, Powertrain Material High strength alloy steel, Length 17.556 In, Width 5 In, Height 4.875 In Single Heavy-Duty Rack-and-Pinion Rotary ActuatorsSteel actuators are designed with a 1-pc. pinion shaft and floating pistons, which align themselves to the rack for low internal friction and long piston seal life. Sealed-shaft ball bearings ensure shaft stability, and aid with heavy load and impact capabilities. Hard-coated aluminum body is impregnated with PTFE for wear resistance and lower actuator friction. Built-in angle adjustments reduce the angle of rotation up to 60 (30 per end of rotation).
