Product Overview

The VIS30 geroler orbit hydraulic motor is a universal replacement motor for Eaton Char-Lynn VIS30 and equivalent Danfoss VIS30 hydraulic drive units, widely applied in light to medium load hydraulic equipment.

It adopts the classic geroler orbit disc valve design, which converts hydraulic pressure into stable low-speed high-torque mechanical rotation. All internal core components are precision machined with high wear-resistant alloy material, matched with double-sided ball bearing support and full NBR sealing structure. The whole machine meets original OEM installation size, port position and shaft parameters, realizing true plug-and-play replacement, no need to modify pipeline or mounting bracket.

The robust cast iron outer shell can resist mud, dust and slight impact on construction sites and farms. The built-in one-way check valve effectively prevents equipment runaway caused by hydraulic back pressure during shutdown, greatly improving operational safety. All finished motors are subjected to full hydraulic performance testing to ensure consistent output torque and zero leakage.

Key Features

✅ Full OEM Interchangeability Perfectly matches Eaton Char-Lynn VIS30 & Danfoss VIS30 series dimensions, direct drop-in replacement without machining or adjustment.

✅ Reliable Geroler Disc Valve Mechanism Precision machined geroler gear set and balanced disc valve ensure uniform torque output, low pulsation and quiet operation at variable speeds.

✅ Durable Cast Iron Housing High-strength cast iron shell resists impact, dust and temperature fluctuation, suitable for outdoor construction and farm harsh environments.

✅ Complete Leak-proof Sealing System High temperature resistant NBR shaft and body seals eliminate internal & external oil leakage, stable performance under continuous high pressure.

✅ Dual Heavy-duty Ball Bearings Front and rear double ball bearing structure bears radial and axial loads, reducing friction and prolonging motor service lifespan.

✅ Built-in Anti-reverse Check Valve Integrated safety check valve avoids pressure backflow and sudden rotation surges, improving equipment operation safety.

✅ Strict Factory Quality Inspection Each motor undergoes flow, pressure and leak tightness testing before shipment to eliminate defective products.
