Import Bmr Hydraulic Motor — Buy in Bulk from Supplier in China

The BMR hydraulic motor from Shijiazhuang Hanjiu Hydraulic Co., Ltd. is an orbital hydraulic motor built around an advanced gerotor (gerolor) gear set with shaft distribution flow. The design enables automatic pressure compensation during high-pressure operation, delivering reliable and smooth rotation for mobile and semi-stationary machinery. Key engineering features include low start-up torque pressure, high-pressure shaft seal capability for series or parallel operation, a reinforced drive-linker for extended service life, and a low-noise distribution system. The compact form factor and straightforward installation geometry suit original equipment integration and aftermarket replacement in brush cutters, mowers, harvesting equipment, forestry machinery, and turf equipment.

The gerolor gear set represents a refined orbital motor architecture where an internal gear with one fewer tooth than the external ring gear orbits eccentrically, generating sealed volume chambers that translate hydraulic pressure into rotary motion. This contrasts with gerotor designs where tooth counts differ by one, with gerolor configurations typically offering smoother torque delivery and reduced internal leakage at equivalent pressures. Standard material specifications for BMR-series orbital motors include a cast iron or aluminium alloy housing, nitrile rubber or fluorocarbon shaft seals, and hardened alloy steel gerolor set with surface treatments for wear resistance. Typical operating pressures range from 140 to 200 bar continuous, with intermittent peaks to 225-250 bar, though buyers must confirm exact ratings with Shijiazhuang Hanjiu Hydraulic as the source does not state pressure limits.

Primary applications span agricultural and grounds maintenance machinery where compact, high-torque hydraulic drive is required at moderate speeds. Brush cutters and flail mowers utilise these motors for direct-drive cutter heads, while combine harvesters and forage harvesters employ them for header reel drives or conveyor systems. Forestry equipment such as delimbers and small forwarders, plus commercial turf mowers and aerators, represent further demand segments. Buyers should confirm with Shijiazhuang Hanjiu Hydraulic whether the motor is supplied with standard SAE-A or SAE-B mounting flanges, BSP or UNF port threading, and whether output shafts are available in keyed, splined, or tapered configurations to match existing drivetrain interfaces.

Shijiazhuang Hanjiu Hydraulic Co., Ltd. is headquartered in Shijiazhuang, Hebei Province, China, postal code 050000. The company holds a harbour trust tier on the platform. The response rate is recorded at 0.00 percent with zero average response hours, indicating no response data is available. The supplier's profile focuses on hydraulic drive components, with this BMR orbital motor representing its offering in the gerolor gear set motor segment. No additional manufacturing certifications, production capacity figures, or export history is provided in the source material. The location in Shijiazhuang places the company within Hebei's industrial manufacturing base, though this does not independently verify production capabilities or quality management systems.

The listing presents Shijiazhuang Hanjiu Hydraulic as a manufacturer of orbital hydraulic motors for agricultural, forestry, and grounds maintenance machinery. The product description emphasises engineering features including the gerolor gear set, shaft distribution flow, and reinforced drive-linker, suggesting technical product development rather than pure trading. However, the absence of response data means buyers cannot assess communication responsiveness through platform metrics. The company profile does not state ISO 9001 certification, factory audit status, or OEM client references. Buyers should conduct direct due diligence to confirm whether Shijiazhuang Hanjiu Hydraulic manufactures these motors in-house or sources gear sets from third parties, and whether technical support includes hydraulic circuit sizing assistance for integrators.
