Product Description
Eaton Char-Lynn 158 Series LSHT Hydraulic Motors
Product Overview: The Eaton Char-Lynn 158 Series (built on the legacy of the 101 Series) is a global benchmark for industrial-grade LSHT (Low Speed High Torque) performance. Renowned for its compact envelope and exceptional radial/axial load capacity, the 158 series is engineered for durability in the most punishing environments. This category focuses on precision part numbers: 158-3425-001 and 158-3284-001.
The 158 series incorporates Eaton’s patented Geroler technology, which minimizes internal friction to ensure smooth, consistent torque delivery even at ultra-low speeds. These motors are the premier choice for compact propulsion drives, agricultural mowers, injection mold adjustments, and material handling conveyors.
Key Technical Advantages:
Geroler Gear Set: Delivers significantly higher mechanical efficiency and a longer service life compared to standard gerotors, especially during continuous high-pressure cycles.
Optimized Spool Valve Design: The advanced spool valve architecture allows for a lightweight, compact footprint, ideal for space-constrained mechanical integrations.
High-Pressure Sealing: Features premium shaft seals designed to handle back-pressure spikes, reducing maintenance intervals and downtime.
Precise OEM Interchangeability:
158-3425-001: Standard LSHT configuration for guaranteed 1:1 fit-and-function replacement of original Eaton units.
158-3284-001: Industrial-grade part number optimized for specific torque-to-speed ratios.
