The BMR series is a universal family of spool valve orbital hydraulic motors utilizing an advanced Geroler gear set design. Unlike basic gerotor setups, the BMR incorporates precision steel rollers on the teeth of the outer ring. These rollers reduce mechanical friction, yield higher starting torque, lower startup pressure, and significantly prolong operational life under medium-duty cyclic loads.
Geroler Rolling Mechanism: Employs rolling contacts rather than standard sliding configurations to boost mechanical efficiency, control noise, and guarantee smooth slow-speed rotation.
Axial Distribution Flow: Features a space-saving spool valve structure combined with axial oil flow routing for a compact size and lower component weight.
High-Pressure Shaft Seal: Fitted with a robust dynamic shaft seal capable of handling severe backpressure. This allows multiple motors to be plumbed directly in series or in parallel without instantly popping the seal.
Integrated Check Valves: Houses internal non-return check valves that auto-drain case pressure back to the low-pressure side, minimizing the strict need for an external third-line case drain under normal setups.
Enhanced Bearing Support: Standard builds combine deep groove ball bearings or needle bearings onto the output shaft assembly to absorb moderate radial and axial forces from drives, gears, or pulleys.
| Parameter | Range / Value | Metric & US Units | Notes |
|---|---|---|---|
| Displacement | 36 ~ 400 | cc/rev (cm³/rev) | Different internal gear width determines the displacement volume. |
| Max. Speed | 5 ~ 1085 | RPM | Small displacement motors run at higher speed, large displacement motors run at lower speed. |
| Max. Continuous Torque | 100 ~ 390 | N·m | Large displacement models can reach above 380 N·m under continuous operation. |
| Max. Intermittent Torque | 120 ~ 490 | N·m | Peak torque allowed under instantaneous or impact load. |
| Max. Continuous Pressure | 100 ~ 140 | bar (approx. 1450 ~ 2030 psi) | Small displacement max. 140 bar, large displacement usually requires pressure reduction. |
| Max. Intermittent Pressure | 140 ~ 175 | bar (approx. 2030 ~ 2540 psi) | Maximum instantaneous pressure peak during shifting, startup or overload. |
| Max. Peak Pressure | 175 ~ 225 | bar (approx. 2540 ~ 3260 psi) | Ultimate impact pressure the system can withstand in extremely short seconds. |
| Max. Oil Flow | 45 ~ 60 | L/min (approx. 12 ~ 16 US gpm) | Max recommended continuous input flow for hydraulic motor, excess flow will cause overheating. |
| Max. Output Power | 4.0 ~ 13.0 | kW | Determined by the product of pressure and flow rate, medium power grade. |
