Whether you are a distributor seeking a stable supply partner or an OEM looking for a cost-optimized BM2 hydraulic motor manufacturer, our team is ready to quote your specification today.

Features & Buyer Benefits

The BM2 series is a Gerotor-type orbital motor (also known as a low-speed high-torque LSHT motor) designed as a direct dimensional and performance equivalent to globally recognized BMR, OMR, and BM2 standards. Every unit leaving our facility is pressure-tested at 100% inspection rate before packaging.

Cross-Brand Compatibility

Direct interchangeable with mainstream BMR / OMR / BM2 / Char-Lynn H series mounting and shaft dimensions
Multiple shaft options: straight keyed Ø25 mm, Ø32 mm, splined 1" 6B, tapered 1:8
Standard SAE A 2-bolt and 4-bolt flange configurations available
G1/2", G3/8", and SAE 10 port threads supported

Performance Advantages

High volumetric efficiency up to 93% via precision-ground Gerotor sets
Low-speed stability down to 10 rpm without stick-slip
Maximum continuous torque up to 470 N·m, peak torque up to 580 N·m
Continuous operating pressure up to 14 MPa (peak 17.5 MPa)
Hardened, precision-machined output shafts rated for 8,000+ hours MTBF

Commercial Benefits for Buyers

Competitive FOB pricing — typically 25–40% below European brand equivalents
MOQ as low as 10 units for trial orders, scalable to 1,000+ units monthly
Stocked SKUs ship in 15 days; custom configurations 25–35 days
White-label and custom-branded packaging available at no tooling cost above MOQ
12-month warranty with traceable serial numbers on every unit

Technical Specifications

Series specifications are selection references. Confirm the complete model code and ordered configuration for pressure, speed, displacement, rotation, shaft, flange and ports. Continuous, intermittent and peak ratings must be distinguished; maximum values are not simultaneous operating limits. Machine fitment requires the OEM part number and machine serial number.

FAQ

Q: Are your BM2 motors fully interchangeable with original BMR/OMR units?

A: Yes. Our BM2 series matches the mounting flange, shaft dimensions, port positions, and performance curves of the industry-standard BMR/OMR specification. Most customers use our motors as drop-in replacements without modifying existing equipment.

Q: What is the BM2 hydraulic motor price range?

A: Pricing varies by displacement, configuration, and order volume. As a guideline, FOB Tianjin prices typically range from USD 28 to USD 95 per unit at 100-piece order quantities. Submit your model list and we will return a formal quotation within 24 hours.

Q: What is the minimum order quantity?

A: For standard catalog SKUs, MOQ is 10 units for sample/trial orders. For OEM-customized units (custom shaft, flange, or branding), MOQ starts at 50 units depending on the modification scope.

Q: How long does production and shipping take?

A: Stocked items ship within 15 days. Customized orders typically require 25–35 days. Sea freight to major ports in Europe and North America takes 28–40 days; we also support DHL, FedEx, and consolidated rail shipping.

Q: What warranty do you provide?

A: Every BM2 motor carries a 12-month warranty from shipment date covering manufacturing defects. Each unit is laser-marked with a unique serial number for traceability across raw material, assembly, and test records.

Q: Do you support sample testing before bulk orders?

A: Absolutely. We strongly encourage technical validation. Samples are available at unit price plus express freight, and sample fees are typically credited against your first bulk order.

Q: Which payment terms do you accept?

A: T/T (30% deposit, 70% before shipment), L/C at sight, Western Union for samples, and Alibaba Trade Assurance. For long-term partners, OA terms are negotiable after the third order.
