Import Bmm50 Orbit Motor — Buy in wholesale FOB from Supplier in China

The BMM50 Orbit Motor from Shijiazhuang Hanjiu Hydraulic Co., Ltd. is the largest displacement variant in the BMM economy series, offering 50.3 cm³/rev in a cast iron housing weighing only 2.4 kg. Its rated speed is 358 rpm, continuous 400 rpm, and intermittent 500 rpm, with rated torque of 33 N·m, continuous 46 N·m, intermittent 88 N·m and peak 100 N·m. Power output is 1.2 kW rated, 1.8 kW continuousд continuous and 3.2 kW intermittent, fed by a maximum continuous flow of 20 L/min. Pressure ratings are more conservative than smaller BMM units: 6 MPa rated, 7 MPa continuous, 14 MPa intermittent and 16 MPa peak, reflecting the larger Gerotor set's mechanical limits.

Shaft distribution flow and an advanced Gerotor manufacturing process keep internal leakage within acceptable bounds for an entry-level orbital motor. The shaft seal is rated for high-pressure operation, enabling series or parallel plumbing without external seal failure. Continuous, intermittent and peak pressure are strictly time-limited: continuous is steady-state, intermittent permits 6 seconds per minute at the higher pressure, and peak allows only 0.6 second per minute. This duty-cycle structure aligns with standard hydraulic test protocols and protects against fatigue in the Gerotor star and ring set.

The BMM50 suits low-speed, high-torque applications where compact packaging matters more than premium efficiency: small agricultural implements, conveyor drives, brush cutter decks and auxiliary hydraulic circuits on compact equipment. Its cross-reference compatibility with M+S Hydraulic MLH, Eaton Char-Lynn, Danfoss OMM and Bosch Rexroth lines allows drop-in substitution in existing machine designs. Buyers should specify shaft diameter, key or splined detail, and port orientation when requesting quotation, as these are not standardised in the source data. Hebei Province manufacturing location offers northern Chinese logistics access, though buyers must confirm export handling and nearest port with the supplier directly.

Shijiazhuang Hanjiu Hydraulic Co., Ltd. operates from Shijiazhuang, Hebei Province, China, with postal code 050000. The company profile shows Harbor trust-tier status, a response rate of 0.00 percent and zero average response hours, indicating limited or untested responsiveness through the platform channel. Buyers should not assume active sales support without direct outreach to verify current operations and export department staffing. The listing targets global markets without specifying regions, and accepts OEM orders without defining minimum engineering involvement or tooling charges.

The BMM50 and its series siblings are positioned as economical alternatives to European and American orbital motor brands, with explicit cross-reference tables to M+S Hydraulic, Eaton Char-Lynn, Danfoss and Bosch Rexroth. No factory certification, year of establishment, production capacity, named clients or revenue data appear in the source. The address places the supplier inland, requiring road haul to Tianjin or Qingdao for containerised sea freight. Prospective buyers should verify business licence, export licence and any ISO quality registration before transferring funds, as these are not displayed in the profile.
