Eaton Char-Lynn S Series Motor | S-380M S-380MS5SXK S-380MS5S-K

Eaton Char-Lynn S Series Heavy-Duty Orbit Motors

Product Overview: The Eaton Char-Lynn S Series is the high-performance benchmark for spool valve hydraulic motors. This category highlights the flagship high-displacement models: S-380M, S-380MS5SXK, and S-380MS5S-K. Designed to deliver exceptional Low Speed High Torque (LSHT) performance within a compact envelope, the S Series features an optimized drive link and internal geometry. Its integrated Geroler® roller set technology minimizes mechanical friction, ensuring unparalleled durability even in the harshest operating environments. These motors are the premier choice for food processing conveyors, harvester brush drives, sweeper auxiliary power, injection molding adjustments, and light winches.

Key Technical Advantages:

• Geroler® Roller Geometry: Unlike standard gerotor designs, the roller-supported set reduces startup pressure and significantly enhances mechanical efficiency under medium-to-high pressure cycles.

• High Power Density: The S Series provides robust torque output within a minimal footprint, making it ideal for machinery with restricted installation space.

• Enhanced Bearing Resilience: Engineered to handle higher radial loads than standard spool valve motors, offering superior stability for various drive configurations.

• Technical Decoding:

  • S-380M: The foundational model for the 380cc displacement frame.

  • S-380MS5SXK / S-380MS5S-K: Optimized versions featuring specialized shaft ends (Splined or Keyed) and reinforced sealing systems for demanding duty cycles.
