Product Description
This comprehensive collection features direct-fit OEM replacement parts for the XJFH-4.5/35KFX3 air winch, eliminating compatibility errors and restoring factory-level performance. The lineup includes pneumatic distributing valve components, precision bearings, hardened gears, brake assemblies, air cylinder parts, sealing rings, standard fasteners, and pneumatic control valves. Unlike generic aftermarket parts, these components are forged and machined to match Taian Juling’s original design specifications, calibrated for the winch’s 35kN rated lifting capacity and pneumatic operating pressure (0.4-0.63MPa), ensuring seamless installation and consistent performance in heavy-duty lifting tasks.
Functional Specifications
- Pneumatic Control Components: Distributing valves (XJFH-4.5/35-1003) and air valve assemblies regulate airflow with millisecond response time; pressure regulating valves (GR200-08) maintain stable operating pressure to prevent stalling; quick exhaust valves (QE-02/QE-03) speed up winch brake release and retraction cycles.
- Transmission & Bearing Parts: Precision hardened gears (XJFH-4.5/35-3002b) and spline shafts deliver reliable torque transmission for 4.5-ton rated lifting; heavy-duty bearings (6308, 6412, 42114) reduce rotational friction by 35% and support radial loads up to 120kN.
- Brake System Parts: Disc brake assemblies (XPS-00) and brake pads (XPS-03) provide consistent static braking force to hold heavy loads securely; air cylinders (XJFH-5/35-6008g) actuate brakes reliably even in low-pressure pneumatic conditions.
- Sealing & Fastening Components: Oil seals and O-rings (GB/T3452.1) prevent pneumatic leaks and lubricant loss; high-strength bolts and pins meet GB/T standard specifications for vibration-resistant fastening.
Structural Characteristics
All XJFH-4.5/35KFX3 winch parts feature rugged, industrial-grade construction for maximum durability: gear and shaft components use quenched and tempered alloy steel for 58-62 HRC hardness; brake friction materials offer high heat resistance (up to 280°C) to avoid brake fade; pneumatic valve parts have precision-machined sealing surfaces for zero air leakage; bearings are double-sealed to block dust and debris; all fasteners feature anti-corrosion coating to resist rust in humid and outdoor environments. Components are designed for tool-friendly installation, with standardized mounting interfaces to cut on-site repair time by nearly half.
Applicable Operating Conditions
These spare parts are engineered for the harsh operating environments of the XJFH-4.5/35KFX3 air winch, including:
- Mining, oilfield drilling, and construction sites with heavy-duty vertical lifting and horizontal pulling tasks
- Pneumatic operating pressure range: 0.4MPa to 0.63MPa (standard for industrial air winches)
- Ambient temperatures from -20°C (cold outdoor worksites) to 60°C (high-temperature industrial zones)
- Dusty, humid, and vibration-prone worksites with continuous heavy-duty operation
- Explosion-sensitive industrial environments requiring pneumatic (non-electrical) lifting equipment
Maintenance & Servicing Recommendations
- Pre-Installation Inspection: Verify OEM part numbers and dimensional tolerances against winch technical drawings; clean mounting surfaces to remove dust and debris; check sealing components for cracks or deformation before installation.
- Pneumatic System Maintenance: Inspect air valves, O-rings, and air cylinders for leaks every 1,000 operating hours; replace worn sealing rings and valve springs promptly; lubricate pneumatic components with specialized air winch lubricant quarterly.
- Transmission & Bearing Care: Check gear backlash and bearing clearance every 2,000 hours; replace worn bearings and gears when wear exceeds 0.5mm; re-torque fasteners to specified values to prevent vibration loosening.
- Brake System Upkeep: Inspect brake pads and discs for wear every 1,500 hours; replace brake pads when thickness drops below 3mm; test brake holding capacity under full rated load after repairs.
- Post-Installation Testing: Conduct low-pressure air testing to check for leaks; test winch lifting and braking functions under partial load before full operational use; verify smooth gear rotation and stable pneumatic control.

Field Winch Fault Repair Cases
Case 1: Pneumatic Distributing Valve Leak Causing Winch Stalling
An XJFH-4.5/35KFX3 air winch on a mining site stalled mid-lift due to severe air leakage from a worn distributing valve core (XJFH-4.5/35-1200) and damaged valve sleeve. The pressure loss made the winch unable to generate sufficient lifting torque. Replacing the faulty valve core, sleeve, and sealing gaskets restored normal airflow and pressure, allowing the winch to resume full-load lifting operations.
Case 2: Worn Brake Pads Leading to Load Slippage
A drilling site XJFH-4.5/35KFX3 winch experienced dangerous load slippage during operation, caused by heavily worn brake pads (XPS-03) that lost friction capacity. The worn pads failed to hold the rated 4.5-ton load, creating a safety hazard. Installing new OEM-spec brake pads and adjusting brake clearance eliminated slippage and restored reliable braking performance.
Case 3: Bearing Failure Causing Gear Transmission Noise
An XJFH-4.5/35KFX3 winch produced loud abnormal noise and rough rotation, traced to a seized 6308 bearing (GB276-6308) due to dust contamination and lack of lubrication. The failed bearing damaged gear meshing and disrupted power transmission. Replacing the worn bearing and re-lubricating the gearbox eliminated noise and restored smooth, stable winch rotation.
Frequently Asked Questions (FAQ)
