Product Introduction
This curated collection of drilling rig spares covers all critical rig subsystems: pneumatic clutch/air motor assemblies (AD45000 series), hydraulic brake components (PS7024), precision bearings, sealing kits, control valves (5127 series), mud pump parts, pneumatic/hydraulic actuators, rig safety hardware, and Ex-proof electrical fixtures. All parts are designed for direct, modification-free installation into standard drilling rigs, with OEM-matched form, fit, and function to ensure seamless integration with existing rig systems.
Functional Description
- Power & Torque Transmission: AD45000 series clutch/air motor assemblies and pneumatic tyre clutches deliver reliable power transfer for rig rotating systems, supporting heavy-load drilling operations with stable torque output
- Brake & Safety Control: PS7024 hydraulic disc brake pads and brake bands provide responsive, high-friction braking for rig hoisting systems; safety chains and anti-clash valves enhance rig operational safety
- Fluid Power Regulation: 5127 series shuttle valves, reversing valves, and relief valves control hydraulic/pneumatic fluid flow and pressure (up to 1.6MPa), enabling precise rig actuation and motion control
- Mud Pump & Hydraulic System Support: QC0100 piston assemblies, gear oil lubrication pumps, and axial piston pumps maintain stable mud circulation and hydraulic power supply for core rig functions
- Sealing & Contamination Control: Oil seals, piston rings, and seal cushions prevent fluid leakages and block debris ingress, extending the service life of rotating and hydraulic components
- Rig Safety & Electrical Compliance: Ex-proof lamps, thermal relays, and emergency fixtures meet hazardous area certification requirements, ensuring safe electrical operation on rig floors
Structural Features
- Heavy-Duty Construction: Brake pads use high-friction, wear-resistant composite materials; bearings adopt high-carbon chromium alloy steel for heavy radial/axial load capacity (up to 50KN for hoist bearings)
- Precision Machining: Valves, pistons, and clutch components feature micron-level dimensional accuracy, ensuring tight fits and stable system performance
- Ex-Proof & Compliance Design: Electrical components carry IECEx and rig hazardous area certifications, suitable for Zone 1/2 explosive gas environments
- Drop-In Replacement: All spares follow OEM mounting dimensions and connection interfaces, reducing installation labor time by up to 60% compared to custom-fabricated parts

Field Fault Repair Cases
Case 1: PS7024 Hydraulic Brake Pad Wear Causing Brake Lag
A land drilling rig experienced delayed brake response and reduced stopping power, traced to heavily worn PS702407-00 hydraulic disc brake pads. The worn pads compromised braking safety and halted drilling operations. Replacing all worn brake pads with OEM-spec PS7024 components restored full braking responsiveness, complying with rig safety standards and resuming drilling in 2 hours.
Case 2: 5127 Series Shuttle Valve Failure Causing Hydraulic Malfunction
An offshore rig’s hydraulic control system failed to actuate properly due to a faulty 5127041106 shuttle valve. The valve blockage disrupted fluid flow, leaving rig hoist functions inoperable. Installing a new 5127 series shuttle valve and flushing the hydraulic line resolved the flow issue, restoring full rig hydraulic control.
Case 3: AD45000 Clutch Assembly Wear Causing Power Loss
A rig’s power transmission system suffered intermittent power loss, caused by a worn AD450001-2200B1 clutch assembly. The damaged clutch failed to transfer torque efficiently, slowing drilling progress. Replacing the clutch assembly and performing alignment adjustments restored full power transmission, eliminating downtime and performance fluctuations.
