Danfoss OMS Motor | OMS-160 151F0503 OMS-200 151F0570 | Disc Valve Orbit Motor

Danfoss OMS Series Heavy-Duty Disc Valve Orbit Motors

Product Overview: The Danfoss OMS Series orbital motor is the industry standard for high-performance drives in medium-to-heavy duty applications. This category features the flagship models: OMS-160 (151F0503) and OMS-200 (151F0570). Engineered with advanced Disc Valve technology and the signature Geroler® roller set, the OMS series delivers massive starting torque and maintains exceptional stability under extreme high-pressure conditions. Its robust bearing design and elite sealing system make it the premier choice for agricultural propel drives, heavy-duty conveyors, road construction machinery, injection molding machines, and marine deck equipment.

Key Technical Advantages:

• Disc Valve Precision: The independent valve plate design automatically compensates for wear-related clearances, offering superior volumetric efficiency and more stable low-speed performance compared to spool valve motors.

• Geroler® Roller Geometry: Incorporates roller contacts in the gear set to minimize mechanical friction, ensuring pulse-free operation in Low Speed High Torque (LSHT) conditions and significantly extending service life.

• Elite Bearing Load Resilience: Equipped with oversized tapered roller bearings, the motor shaft handles immense radial and axial loads directly—eliminating the need for external bearing supports.

• High-Performance Sealing: Features a high-pressure resistant shaft seal that manages significant back-pressure, ensuring leak-free performance in harsh industrial and outdoor environments.

• Technical Spec Decoding:

  • 151F0503 (OMS-160): 160cc frame with standard 4-bolt flange and keyed shaft.

  • 151F0570 (OMS-200): 200cc frame optimized for applications requiring higher torque output.
