Eaton Char-Lynn H Series Motor | 110A-106-AS-0 110A-054-AM-0 | 112A 116A

The Eaton Char-Lynn H Series (including 110A, 112A, and 116A) from LIC Hydraulic is the global benchmark for Spool Valve Gerotor Motors. Designed for Low-Speed High-Torque (LSHT) applications, these motors offer a high power-to-weight ratio in a compact, economical package. Models like the 110A-106-AS-0 and 110A-054-AM-0 are trusted by OEMs worldwide for their reliability and smooth performance. We provide 100% drop-in replacements that match original Char-Lynn mounting patterns, shaft splines (1″ Keyed, Splined, etc.), and porting (7/8-14 UNF or G 1/2).

Technical Highlights

• Displacement Range: From $59\text{ cc/rev}$ (036) up to $450\text{ cc/rev}$ (273).

• Max Pressure: Continuous up to $124\text{ bar}$ ($1800\text{ psi}$); Intermittent up to $165\text{ bar}$.

• Flow Rate: Rated up to $57\text{ L/min}$ ($15\text{ gpm}$).

• Config: Standard 2-bolt SAE A or 4-bolt flanges.

Core Advantages

• Spool Valve Precision: The spool valve design provides precise timing, ensuring that the fluid is delivered to the gerotor at exactly the right moment. This results in superior mechanical efficiency and consistent speed control.

• Self-Lubricating Internal Components: The hydraulic fluid itself provides constant lubrication to the drive link and bearings, significantly reducing mechanical wear and extending the motor’s service life in high-cycle applications.

• High Back-Pressure Capability: Thanks to the high-pressure shaft seal, the H series can be used in series circuits (where one motor exhausts into another) without the immediate need for a dedicated case drain line.

• Universal Interchangeability: Every 110A unit we produce is machined to sub-micron tolerances, ensuring that it replaces your existing Char-Lynn, Danfoss, or White motor without any modification to your machinery.

Expert Maintenance Tips

• Radial Load Management: While the H series is robust, excessive radial load (from belts or chains) can cause premature bearing failure. For heavy-duty side loading, ensure your model (like the 116A) is equipped with reinforced bearings.

• Startup Procedure: Always purge the air from the system before applying full load. Air trapped in the gerotor pocket can cause localized dry-running and “scoring” of the wear plates.

• Fluid Cleanliness: To protect the precision spool valve, maintain oil cleanliness at ISO 18/16/13. Fine particulates act like sandpaper on the spool, leading to internal leakage and loss of speed control.
