HMR105-02 Linde Variable Piston Motor 105 cm³ 420 bar

Product Overview:

The HMR105-02 0001 belongs to the Linde Series 02 (HMR / HMF / HMV / related HPV sizes 35/55/75/105/135/165) high-pressure variable / self-regulating axial piston motors. Featuring a swash-plate design for open and closed circuit systems, these motors offer excellent low-speed stability, high starting torque and a wide conversion range. Fully interchangeable with genuine Linde units, they enable direct drop-in replacement without modification to mounting interfaces or piping. Every unit undergoes 100% simulated operating-condition testing to ensure high power density and long service life under high pressure.

Key Technical Advantages:

1. High-Pressure Self-Regulating Design: Continuous rating of 420 bar and peak of 500 bar. Automatically adjusts displacement according to system pressure for optimal torque matching and efficient operation.
2. Excellent Low-Speed Performance & High Starting Torque: Optimised start-up and low-speed characteristics ensure smooth running and strong starting torque for precise control applications.
3. Wide Conversion Range & Fast Response: Displacement is adjustable over a wide range with dynamic response, supporting flexible open and closed circuit applications.
4. Compact Design & High Power Density: Swash-plate construction is compact with high power density. Optional PTO through-drive facilitates system integration.
5. True Interchangeability & Long Service Life: Fully compatible with OEM SAE mounting flanges and spline shafts. High-load bearings ensure reliable long-term operation.

Application Areas:

• Travel and swing drives on construction machinery (excavators, loaders, cranes)
• Agricultural and forestry equipment hydraulic transmissions
• Port and material-handling equipment
• Industrial open/closed circuit hydraulic systems
• Any mobile or stationary application requiring high starting torque and variable control

Expert Maintenance Tips:

1. Ensure proper SAE flange alignment during installation. Tighten shaft-end fasteners to specified torque and verify correct rotation and port connections.
2. Use anti-wear hydraulic oil meeting required cleanliness levels; system filtration should be at least 10 μm. Thoroughly bleed air before initial start-up.
3. Regularly check case pressure (max. 2.5 bar) and oil temperature to prevent over-pressure. Monitor regulation begin pressure settings.
4. During service, inspect pistons, slippers and valve plate for wear; replace complete rotating groups when necessary. Store long-term units in a dry environment and rotate the shaft periodically.
