BM5 Series Hydraulic Motors

BM5 Series Hydraulic Motors | Low Speed High Torque Orbital Motor Manufacturer

Sourcing reliable BM5 series orbital motors for your industrial machinery, agricultural equipment, or hydraulic system integration? Olive Branch Hydraulics, a specialized BM5 hydraulic motor manufacturer based in Hebei, China, delivers fully compatible BM5 series units engineered for demanding low-speed, high-torque applications. With over 10 years of OEM production experience, ISO-grade machining tolerances, and a 100% pressure-tested output policy, we supply distributors, wholesalers, and OEM equipment builders worldwide with motors that match or exceed Danfoss OMP / White Drive / M+S BM5 dimensional and performance standards. Competitive FOB pricing, 15–25 day lead times, and white-label packaging available on every order.

Features & Benefits

The BM5 series is a gerotor-based orbital hydraulic motor designed to convert hydraulic energy into rotational mechanical output at low rotational speeds with exceptionally high starting torque. Our manufacturing program focuses on three buyer priorities: interchangeability, durability, and delivery reliability.

• Drop-in Compatibility: Mounting flange, shaft dimensions, and port configurations are fully interchangeable with mainstream BM5 / OMP / SMP series — eliminating redesign costs for your end customers.
• High Volumetric Efficiency: Up to 92% volumetric efficiency through precision-ground gerotor sets (tolerance ≤ 0.005 mm), reducing internal leakage and extending service life.
• High Starting Torque: Starting torque reaches 90% of theoretical torque, ideal for conveyors, winches, sweepers, augers, and agricultural drives.
• Robust Pressure Rating: Continuous pressure 14 MPa, intermittent peak 17.5 MPa, max 21 MPa — built with hardened cast iron housing and chrome-plated output shafts.
• 100% Tested Output: Every motor undergoes a no-load run-in test, pressure test, and leakage test before crating.
• Wide Displacement Range: 8 standard displacements from 50 cc/rev to 400 cc/rev cover the majority of mobile and industrial applications.
• Cost Advantage: Direct-from-factory pricing — typically 30–45% below European-branded equivalents at equivalent tolerance grades.

Typical Applications

• Agricultural machinery: seeders, sprayers, rotary cutters, feeder mixers
• Construction equipment: skid steer attachments, mini excavators, road sweepers
• Industrial systems: conveyor drives, packaging lines, plastic recycling
• Marine & winch systems: anchor windlasses, capstan drives
• Municipal vehicles: sweepers, snow blowers, hydraulic fan drives

Technical Specifications

The table is a selection reference requiring model-specific confirmation of continuous, intermittent and peak ratings. Maximum speed, torque, pressure and flow are not simultaneous operating points. At 396.5 cm³/rev and an 11.5 MPa pressure differential, ideal theoretical torque is about 726 N·m before mechanical losses; the previous 800 N·m value is not supported by these conditions. Custom displacements, shaft profiles (straight keyed, splined 6B/13T, tapered 1:10), and port options (G1/2", SAE-10, M22×1.5) are available on request.

Construction & Materials

OEM / ODM Capabilities

As a dedicated BM5 hydraulic motor wholesale partner, Olive Branch Hydraulics is structured to serve importers, distributors, and equipment manufacturers who require private-label production rather than retail-grade goods. Approximately 70% of our annual output ships under client brand identities to markets in North America, Europe, the Middle East, and Southeast Asia.

What We Customize

• Branding: Laser-engraved nameplates, silk-screen housing logos, color-matched powder coating (RAL standard).
• Packaging: White-label cartons, custom inner foam, multilingual user manuals, barcode & SKU labeling per your ERP system.
• Mechanical Customization: Non-standard shaft lengths, alternative flange patterns (SAE A 2-bolt / 4-bolt, Cyclo), integrated relief valves, anti-cavitation valves.
• Performance Tuning: Adjusted displacement, FKM seals for high-temp applications, marine-grade corrosion coating.
• Documentation: Country-of-origin certificates, CE declarations, customized test reports per batch.
