OMT BMT Series Motor | OMTW400 OMT400FN OMT160/250/315/400 | Heavy Duty Orbit Motor

OMT / BMT / OMTW Series Heavy-Duty Disc Valve Hydraulic Motors

Product Overview: The OMT and BMT Series motors represent the high-end performance standard for orbital hydraulic technology. As heavy-duty models featuring an advanced Disc Valve distribution mechanism, this page highlights the core displacements: OMT 160, 250, 315, and 400, along with specific models OMTW400-11116528 (Wheel Mount) and OMT400FN-151B4025. Engineered for extreme radial loads and continuous high-pressure environments, the Geroler® roller gear set ensures precise and smooth power delivery in Low Speed High Torque (LSHT) applications.

Key Technical Advantages:

• Disc Valve Precision: The valve mechanism is independent of the main shaft, automatically compensating for wear to maintain peak volumetric efficiency under long-term heavy usage.

• Superior Load Capacity: Equipped with oversized tapered roller bearings, the housing handles massive radial forces—ideal for direct-drive wheels, mixers, or winches.

• OMTW Wheel Mount Design: The unique recessed flange design of the OMTW series allows the motor to sit inside the wheel hub, significantly shortening the axial length of the drivetrain.

• High Back-Pressure Resilience: Reinforced shaft seals ensure zero-leakage performance even in systems with high back-pressure or frequent directional reversals.

• Technical Decoding:

  • OMT / BMT 160-400: Represents a displacement range from 160cc to 400cc, catering to various tractive effort requirements.

  • OMTW400-11116528: 400cc Wheel Mount motor, frequently used in self-propelled heavy machinery.

  • OMT400FN: A heavy-duty specification featuring specific flange and porting interfaces.
