About the HTR series
Purpose-built rotary power for the most demanding hydraulic applications
The Parker HTR series delivers precise, high-torque rotary motion using a proven rack & pinion design. From compact automation to heavy industrial handling, these actuators combine a shock-resistant ductile iron housing, large tapered roller bearings and adjustable cushions for reliable service in the harshest environments.
As an official Parker Hannifin distributor, HidroNEX supplies factory-spec HTR actuators with full warranty, technical support and configuration advice for your exact application.
Typical applications
- Steel & casting handling
- Marine & offshore boom slewing
- Oil & gas valve actuation
- Mobile equipment (aerial lifts, refuse tippers)
- Solar panel rotation
- Water & flood-gate management
- Tunnel boring & long-hole drilling
- Plastics — blow & injection molding
Engineering features
Built to keep working, engineered to be serviced
Rack & Pinion
Through-hardened, high-strength alloy steel rack and pinion for long service life in demanding applications.
Ductile Iron Housing
Heavy, shock-resistant housing drives large output torque and shrugs off harsh operating environments.
Tapered Roller Bearings
Generously sized bearings support large external axial and radial loads on the shaft.
Adjustable Cushions
Floating cushion bushing acts as a high-performance check valve with a needle-valve exhaust for tunable deceleration.
Replaceable Wear Parts
Bronze rack bearing, PTFE wear bands and dual-lip pinion seals designed for in-field service.
Fluorocarbon Seals
22V seal package rated for high-temperature and synthetic hydraulic fluids common in industrial hydraulic circuits.
Available now
Three configured HTR models
All three share the same core configuration — 90° rotation, TG face mount, single male keyed shaft, fluorocarbon seals and end-of-stroke cushions. Pick the model that matches your torque requirement.
