MM Series Ultra-Compact Micro Orbital Hydraulic Motors

Product Overview: The MM Series (equivalent to OML type) is the “lightweight specialist” of the hydraulic motor family, specifically engineered for applications where installation space is extremely limited. This category features the full range of micro-displacement models: MM8C, MM12.5C, MM20C, MM32C, MM40C, MM50C, and flange-optimized variants like MS.MM125C, MMFS20C, MMFS32C, and MMFS50C. Utilizing advanced Spool Valve technology and a compact gerotor set, MM motors excel in high-speed operations. They are the premier choice for precision machine tool attachments, conveyor line drives, textile machinery, small agricultural implements, and automated production lines.

Key Technical Advantages:

• Ultra-Miniature Architecture: Exceptionally small outer diameter and length allow for seamless integration into handheld devices or micro-machinery.

• High-Speed Performance: Optimized for high-frequency and rapid-response tasks, with maximum speeds exceeding 1000 RPM.

• Integrated Mounting Options: Offers multiple flange types (such as MMC standard and MMFS 4-bolt flanges), supporting flexible side or end porting configurations.

• Long-Life Sealing: Equipped with premium wear-resistant shaft seals to maintain integrity even during prolonged high-speed rotation, reducing maintenance intervals.

• Technical Spec Decoding:

  • MM / MS.MM: Identifies the standard micro-orbital motor sequence.

  • MMFS: Represents the square flange mounting sequence for enhanced installation stability.

  • 8C – 50C: Displacement identifiers (8cc to 50cc), covering needs from high-speed light duty to precise low-torque tasks.
