BME-300 BMER Series LSHT Orbit Motor High Torque

Product Overview

The BME-300 (BMER / OMER / BMER-1 / BMER-2 Series) is a low-speed high-torque (LSHT) orbital hydraulic motor featuring a Rolortorc / Geroler gear set design for medium-to-heavy-duty applications requiring high starting torque and smooth low-speed operation. It offers high volumetric efficiency, compact construction and reliable performance. Fully interchangeable with Danfoss OMP / OMR / OMS and Parker TE / TG / TF series, these motors are validated under simulated operating conditions for dependable service in agricultural, construction and industrial hydraulic systems.

Key Technical Advantages

1. Advanced Rolortorc / Geroler gear set design delivers high efficiency, low starting pressure, smooth operation and low noise.
2. High-pressure shaft seal and bearing configuration support elevated return pressure and side loads, enabling series or parallel operation.
3. Precision machining ensures high volumetric efficiency and long service life under medium-to-heavy continuous duty.
4. Compact design with multiple flange, shaft and port options facilitates full drop-in interchangeability with major brand equivalents.
5. 100% simulated operating condition testing validates performance consistency under real pressure, flow and load conditions.

Application Areas

Agricultural machinery, construction vehicles, material handling equipment, winches and hoists, augers, forestry equipment, and other mobile or stationary hydraulic systems requiring high torque at low to medium speeds.

Expert Maintenance Tips

Ensure precise flange alignment and control side loads during installation. Use anti-wear hydraulic oil with operating viscosity of 20–43 cSt and keep oil temperature below 80°C. Run at reduced load for initial break-in. Regularly inspect the shaft seal and fluid cleanliness. Limit intermittent operation to no more than 10% of each minute. In case of abnormal performance, first check system contamination and fluid condition. Use matching seal kits for service.
