Product Overview

 

The Danfoss OMT315 4-bolt gerotor hydraulic motor is a large-displacement low-speed high-torque (LSHT) hydraulic motor from the Danfoss OMT series, specially designed for heavy-duty travel drives and industrial applications. This model adopts a 4-Bolt Square Flange mounting method, and can be optionally equipped with a 1:8 or 1:10 Tapered Shaft, delivering powerful and stable power output for traveling, slewing and attachment drives of various heavy-duty equipment.

As a core model of the Danfoss OMT series, the OMT315 is renowned for its continuous torque of 950 N·m and displacement of 326.3 cm³/rev. Equipped with an advanced Geroler roller gerotor gear set and a disc-type flow distribution structure, this motor efficiently converts hydraulic energy into mechanical energy. It is an ideal drive solution for heavy-duty equipment including mobile crushing stations, skid steer loaders and combine harvesters. This product is fully interchangeable with mainstream models such as Danfoss OMT315 and BMT-315-4-M-D, and is applicable to various domestic and foreign crushing bucket equipment and travel drive systems.

 

Technical Advantages

 

1. Roller Geroler Gear Set

  • OMT315 uses advanced roller Geroler cycloidal gears, better than traditional Gerotor structures.
  • Rolling friction improves mechanical efficiency and cuts energy loss for heavy-duty demolition bucket applications.
  • Starting torque exceeds 90% theoretical torque, torque loss<0.5%, with stable long-term performance and low noise.

2. End-Face Disc Valve Technology

  • Adopts premium disc valves instead of conventional spool valves.
  • Automatic wear compensation maintains high volumetric efficiency.
  • Optimized flow channels reduce pressure drop and save energy.
  • Universal shaft-driven valve plate ensures precise flow control, keeping high efficiency under high pressure and variable loads for demolition buckets.
