Product details

1. Product Name Breakdown

• Hydraulic Pump Spare Parts

Spare components for hydraulic pump repair or replacement.

• V90N280 Drift Shaft

• V90N280: Model code (typically indicates pump series or displacement, e.g., 280cc/rev).

• Drift Shaft: A floating/sliding shaft that transmits torque between the motor and pump internals, allowing axial/radial misalignment compensation.

• Complete with Bearing

Pre-assembled bearings (e.g., radial ball bearings, cylindrical roller bearings) for rotational support and load reduction.

------

2. Core Functions

• Power Transmission & Misalignment Compensation

• Transfers motor torque to hydraulic pump gears/pistons.

• Floating design absorbs vibration and compensates for assembly tolerances/thermal expansion.

• Bearing Support

• Pre-installed bearings ensure rotational precision, reduce noise, and extend service life.

• Typical configuration: Double-row angular contact bearings (axial load) + Deep groove ball bearings (radial load).

3. Technical Specifications (Example)

【表格】

Parameter Description

Compatible Pump V90N280 series hydraulic pumps (e.g., V90N280-01, V90N280-02 variants)

Shaft Material 42CrMo4 alloy steel (quenched, hardness HRC52-56)

Bearing Type Imported NSK/SKF bearings (e.g., 7210AC angular contact + 6208 deep groove)

Shaft Diameter 50mm (keyway width 14mm, ISO 1088 compliant)

Length 280mm (including bearing mounting sections)

Surface Treatment Phosphating + anti-rust oil coating (salt spray test ≥96 hours)

------

4. Typical Applications

• Construction Machinery

• Replacement for excavator/loader hydraulic main pump shafts damaged by sand intrusion or overload.

• Industrial Equipment

• Repair of injection molding machine/die-casting machine hydraulic systems to resolve pressure fluctuations caused by axial runout.

• Marine & Offshore

• Deck machinery hydraulic pump shaft replacement for corrosion resistance in high-salinity environments.

------

5. Installation & Maintenance

• Installation Steps

1. Clean pump housing bore and remove old sealant residues.

2. Apply LOCTITE 648 bearing retainer to shaft journal surface.

3. Align keyway and gently tap shaft end with brass hammer until mating surface contacts.

4. Install bearing end cover (torque: 80-100N·m, refer to pump manual).

• Maintenance Cycle

• Inspect bearing clearance every 2,000 hours (measure with dial indicator, axial clearance ≥0.05mm).

• Lubricate with lithium-based grease (NLGI Grade 2) every 500 hours.

• Troubleshooting

• Abnormal Noise: Check excessive bearing preload (axial clearance <0.05mm).

• Shaft End Oil Leak: Verify O-ring integrity (model: Φ85×3.55mm).
