SMRS & SMS Series Hydraulic Motor | SMRS-200 SMRS-305 SMRS-395 | Gerotor Motor

LIC Hydraulic specializes in the SMRS & SMS Series, premium orbit hydraulic motors utilizing advanced gerotor/geroler technology. Designed for versatility, the SMRS series (from SMRS-200 to SMRS-395) provides immense torque at low speeds for heavy-duty drive systems, while the SMS-80 excels in higher-speed, compact applications. These motors feature a disc-distribution valve and robust internal bearings, making them the industry standard for durability in agricultural, municipal, and marine environments. When your application demands smooth rotation and high volumetric efficiency in a small footprint, the SMRS series is the proven choice.

Technical Highlights

• High Torque at Low Speed: Precision-engineered geroler sets provide consistent, high-torque output even at the lowest RPMs.

• Enhanced Shaft Loading: Built with high-grade bearings to handle significant radial and axial forces from sprockets and pulleys.

• Universal Mounting: Standard SAE or ISO mounting flanges and shaft options (keyed, splined) for easy drop-in replacement of HMT, SMS, and SMP series motors.

• Excellent Sealing Performance: Advanced shaft seals allow for operation under high backpressure without the immediate need for a case drain in most standard setups.

Application Areas

• Agricultural Machinery: Seeders, harvester reels, and feed mixers.

• Marine Equipment: Fishing winches and small deck cranes.

• Conveyor Systems: Material handling in mining, food processing, and packaging.

Expert Maintenance Tips

• Monitor Case Pressure: To maximize the longevity of the SMRS-395‘s shaft seal, ensure the return line backpressure stays within rated limits.

• Proper Oil Viscosity: For optimal performance and wear protection, use a premium hydraulic fluid with a viscosity of $32\text{–}46\text{ cSt}$ at operating temperatures.

• Avoid Overloading: While robust, exceeding the intermittent torque ratings can lead to internal “scoring” of the valve plate, resulting in reduced efficiency and speed.
