SNU2JN/014 Danfoss Gear Motor GR2 14.4cc 250bar Unidirectional

Product Overview

The SNU2JN/014 (complete model example: SNU2JN/014RN06GAI1E5E6NNXN/VLKNN) is a Danfoss (formerly Sauer-Danfoss/Turolla) GearMe Series Group 2 unidirectional hydraulic gear motor. Featuring an aluminum housing and precision external gear design, it delivers high efficiency, lightweight construction and excellent starting torque. Integrated relief valve (internal drain) and anti-cavitation check valve make it suitable for mobile and industrial hydraulic systems. This unit offers full dimensional and functional interchangeability with genuine Danfoss SNU2JN series motors, matching flange, shaft, ports and overall envelope for direct drop-in replacement. Every unit undergoes 100% simulated operating-condition testing to guarantee consistent performance under high pressure, speed and continuous load.

Key Technical Advantages

1. Pressure-balanced bearing blocks: Pressure-balanced design ensures maximum performance across the full operating range; Teflon-coated bushings extend service life under extreme temperature, pressure and speed conditions.
2. One-piece gear construction: One-piece gears minimize deflection under pressure, combined with precision machining for high volumetric efficiency and low internal leakage.
3. Full interchangeability: Flange, shaft, ports and overall dimensions match genuine Danfoss SNU2JN series units exactly, enabling direct replacement without interface modifications and minimizing downtime.
4. Integrated protection features: Built-in relief valve and anti-cavitation check valve enhance system safety and cavitation resistance for demanding applications.
5. 100% simulated-condition testing: Every unit is fully tested for pressure, speed, leakage and noise characteristics prior to shipment, ensuring consistent out-of-box performance.

Application Areas

• Mobile machinery fan drives and auxiliary drives
• Agricultural and construction equipment travel or functional drives
• Industrial conveyor, mixer and light-duty hydraulic systems
• Open- or closed-circuit applications requiring compact size, high starting torque and reliable unidirectional output

Expert Maintenance Tips

1. Before installation, thoroughly clean the shaft and flange face; use correct seals and bolt torque values to avoid misalignment or sealing-surface damage.
2. The system must include adequate filtration and overpressure protection; maintain recommended oil viscosity and ISO cleanliness levels to prevent accelerated gear and bearing wear.
3. Fully warm up the system and verify oil level and circuit pressure before starting; avoid dry starts or cavitation.
4. Regularly monitor leakage rate, noise and case temperature; when changing fluid and filters, follow recommended grades.
5. Protect shaft and ports against corrosion during storage; avoid prolonged exposure to moisture or corrosive environments.
