Hydraulic Gear Motors

The hydraulic gear motors manufactured by GRH are valued for their exceptional durability in tough environments and straightforward, reliable design. These motors are uniquely equipped with an automatic axial clearance compensation feature, which significantly enhances their lifespan. Coupled with sturdy, wear-resistant shaft sleeves, they are built to last. Additionally, the precision-engineered gears ensure a smooth and quiet operation. The robust construction of the pump bodies, made through cold-extrusion, enables them to withstand high pressures, up to 30 MPa, guaranteeing reliable performance even under rigorous conditions. This makes them ideal for a wide array of applications across various industries, including industrial machinery, aerospace, and maritime engineering.

Our hydraulic gear motors are widely used across a range of machinery, playing an important role in agricultural, construction, and road machinery. They power essential equipment such as cranes, aerial platforms, tractors, and harvesters, as well as more specialized machinery like log splitters, forklifts, and excavators. The reliability and versatility of our gear motors make them a preferred choice for driving and controlling a variety of heavy-duty machines.
