Rated Pressure 210 bar (3,045 PSI) continuous, 250 bar (3,625 PSI) peak

Max Speed 800 RPM (at 210 bar inlet pressure)

Torque Output 520 Nm (383 lb-ft) at 210 bar, 620 Nm (457 lb-ft) at 250 bar

Efficiency 88% mechanical, 85% volumetric (typical for orbital motors)

Mounting Style 4-bolt SAE B flange (standard for mobile equipment)

Shaft Configuration 25 mm straight keyed shaft (DIN 5480 compatible)

Porting Parallel SAE 6 (9/16"-18 UNF threads)

Weight 18 kg (39.7 lbs)

Seal Material Nitrile (standard), optional Viton for high-temp/chemical resistance

3. Key Design Features

1. High-Torque Geroler Rotor

• The OMS160 uses a7-lobe rotorwith12-lobed stationary ring, providing30% higher torquevs. standard gerotor designs.

• Example: A 16-ton excavator swing drive using OMS160 achieves95% of OEM torqueat 1,800 PSI.

2. Dual-Lip Shaft Seal

• Reduces oil leakage by70%compared to single-lip seals (tested to 1,000 hours in ISO 188/50 oil).

3. Modular Valve Plate

• Allowsfield-adjustable displacement(140–180 cc/rev) by swapping valve plates (requires recalibration).

4. Thermal Overload Protection

• Built-in bypass valve opens at270 barto prevent motor damage (resets automatically when pressure drops).

4. Applications

• Construction Equipment: Swing drives for 12–20-ton excavators, auger drives.

• Agriculture: Feed mixer drives, hay baler compactors.

• Material Handling: Forklift tilt/mast rotation, conveyor belt drives.

• Industrial Machinery: Plastic injection molding clamping units, winches.

5. Common Failure Modes & Solutions

【表格】

Failure Mode Root Cause Solution

Low Torque/Speed Air in hydraulic system or worn rotor Bleed air; replace rotor if worn

Excessive Heat High backpressure or blocked vents Check relief valve setting; clean vents

Shaft Seal Leakage Worn seal or misaligned shaft Replace seal; check shaft runout

Noisy Operation Cavitation or contaminated oil Increase inlet pressure; change oil

6. Maintenance Recommendations

1. Daily Checks

• Inspect for oil leaks around the shaft seal and port connections.

• Monitor motor temperature (should not exceed105°C / 221°F).

2. 500-Hour Service

• Change hydraulic oil (useISO VG 46or68anti-wear oil).

• Clean the case drain filter (if equipped).

3. 2,000-Hour Service

• Disassemble and inspect the rotor/stator for wear (replace if clearance > 0.15 mm).

• Check valve plate scoring (resurface or replace if pitted).
