SNZ183700007 SNZ Series Hydraulic Orbit Motor

Product Overview

The SNZ183700007, SNZ194301989, 55256996, SNZ192322172 and SNZ202309922 models belong to the SNZ Series Low Speed High Torque (LSHT) orbital hydraulic motors. Featuring a precision Gerotor / Geroler gear set, these motors are engineered for medium-to-heavy-duty applications requiring high torque and smooth low-speed operation. Emphasis is placed on full interchangeability with leading brand equivalents and 100% simulated condition testing to ensure reliable performance and long service life in real hydraulic systems. Suitable for construction, agricultural and industrial drive applications, they deliver high starting torque and consistent output.

Technical Specifications

(Note: After extensive online search of official technical manuals and manufacturer publications, complete verified parameter data for these specific SNZ Series part numbers could not be located. The following is a general engineering description of the series. Actual displacement, continuous/peak pressure, maximum speed, torque, flow and weight must be confirmed against the latest manufacturer documentation or testing. Fabrication of values is strictly avoided.)

• Construction Type: Low-speed high-torque orbital motor (Gerotor / Geroler)
• Control Type: Open-circuit, no integral control valves (typical orbital motor configuration)
• Typical Mounting: Multiple flange and shaft-end options supporting drop-in interchangeability
• Bearings & Seals: High-capacity bearings with high-pressure shaft seal design
• Other: Specific displacement, continuous/intermittent pressure drop, maximum speed, torque, flow and weight require official data or verified testing

Key Technical Advantages

1. Precision-machined orbital gear set delivers high volumetric efficiency and smooth low-speed operation while minimizing internal leakage for improved system efficiency.
2. High starting torque characteristics make the motors well-suited for frequent start-stop and low-speed high-load duty cycles, outperforming conventional high-speed motors in these conditions.
3. Reinforced bearings and high-pressure shaft seal design enhance radial/axial load capacity and sealing reliability, extending service life under demanding conditions.
4. Strong interchangeability with mounting dimensions and interfaces compatible with major brand equivalents, reducing equipment modification and downtime.
5. 100% simulated operating condition testing validates performance consistency and reliability under real pressure, flow and load scenarios.

Application Areas

Construction machinery (drive or swing functions), agricultural equipment (conveyors and drive systems), material handling and lifting equipment, winches and hoists, forestry machinery, and other mobile or stationary hydraulic systems requiring high torque at low to medium speeds.

Expert Maintenance Tips

Ensure precise flange alignment and respect shaft-end load limits during installation. Use anti-wear hydraulic oil with operating viscosity of 20–43 cSt and maintain fluid cleanliness (10–25 μm filtration recommended). Fully bleed the system and run at light load for initial break-in. Regularly inspect the shaft seal, fluid condition and system contamination. Avoid prolonged operation above intermittent pressure ratings. In case of unusual noise, vibration or torque loss, first check fluid cleanliness and system contamination. Use matching seal kits for service to preserve original performance.
