Eaton Char-Lynn H & S Series Spool Valve Hydraulic Orbit Motors

Product Overview: The Eaton Char-Lynn H & S Series derivatives (such as the 112A and 111A series) are enduring classics in the world of orbital hydraulic motors. This category features key models: 112A-088-AT-0-F, 111A-106-AT-0-F, 112A-088-AM-0-F, and 112A-054-A-T. Utilizing proven Spool Valve technology, these motors are engineered to deliver stable power within a highly compact envelope. Integrated with patented Geroler® or Gerotor technology, they ensure smooth, quiet, and pulse-free operation in Low Speed High Torque (LSHT) applications. They are the premier choice for conveyor drives, food processing equipment, small agricultural harvesters, mower auxiliary drives, and light-duty winches.

Key Technical Advantages:

• Ultimate Compactness: Exceptional power density allows these motors to be mounted in extremely restricted spaces while delivering high breakout torque.

• Whisper-Quiet Operation: Optimized timing and precision-machined internal components minimize noise levels across all speed ranges, ideal for indoor environments.

• Rugged Reliability: The spool valve design features fewer moving parts, significantly reducing failure rates and lifecycle maintenance costs.

• Technical Decoding:

  • 112A / 111A Series: Provides a wide range of displacements and mounting options to meet varied torque requirements.

  • Suffix Notation: Denotes specific shaft types (Keyed, Splined), flange styles, and high-pressure seal configurations.
