Function Description

Each spare part is designed to target specific functions and solve practical operational pain points: Hexagon socket head screws (M8×25 W02090081, M8×16 W02090889) and spring washers (W05102008) securely fasten CA2-1 system components, solving the problem of loosening caused by high vibration in oilfield drilling. Bearings (6009-2RZ W21156009, 16009 W21136009) reduce friction between moving parts, ensuring smooth torque transmission and solving the problem of bearing jamming and equipment shutdown. Oil seals (FB25×42×10 W12124252, FB80×105×12 W12124805) and O-rings (60×3.1 W1111600C, 250×5.7 W1122250F) prevent lubricant leakage and dust intrusion, avoiding bearing damage and environmental pollution. CA2-1-specific parts like Torque body CA2-1-25 W90101003 ensure stable torque output, solving the problem of uneven power transmission; first stage sun gear CA2-1-21 W90101009 optimizes power distribution, reducing energy loss. Steel ball Φ8 W29001008 and Disc spring B45×22.4×1.25×2.85 W05400001 enhance system flexibility, solving the problem of rigid operation and component wear.

Structural Features

Our spare parts are designed with robust structures to adapt to the harsh working environments of oilfields: Hexagon socket head screws are made of high-strength alloy steel with heat treatment, ensuring tensile strength of 800MPa and corrosion resistance in humid, corrosive oilfield conditions. Bearings (6009-2RZ W21156009) feature double-sided sealed design, preventing dust and lubricant leakage, and have a smooth inner raceway that reduces friction coefficient to 0.035, extending service life significantly. Oil seals are made of high-temperature resistant nitrile rubber with metal reinforcement, resisting oil erosion and temperature variations from -40°C to 130°C. CA2-1-specific structural parts (Torque body, Bearing housing) are made of precision-cast alloy steel, with surface galvanization treatment, enhancing corrosion resistance and ensuring dimensional accuracy of ±0.02mm, perfectly matching original CA2-1 system components. Disc spring B45×22.4×1.25×2.85 W05400001 has strong elastic resilience, withstanding 10,000 compression cycles without deformation, solving the problem of spring fatigue.

Applicable Working Conditions

Maintenance and Care Suggestions

To extend the service life of spare parts and ensure the stable operation of CA2-1 series systems, our engineers with 26+ years of on-site oilfield maintenance experience provide practical tips (with avoidable pitfalls):

• Fasteners: Check the tightness of Hexagon socket head screws (M8×25 W02090081, M8×30 W02092082) every 100 working hours; replace if thread damage is found. Always use matching spring washers W05102008 to prevent loosening—never use non-standard washers, as they will reduce fastening force and cause component displacement.

• Bearings: Check Bearing 6009-2RZ W21156009 and 16009 W21136009 for temperature and vibration every 90 working hours; replace if temperature exceeds 85°C or vibration amplitude exceeds 0.15mm. Add lubricant every 120 working hours—use lithium-based grease that meets GB/T7324 standards, and avoid over-greasing, which leads to overheating.

• Seals: Inspect Oil seal FB25×42×10 W12124252 and O-ring 60×3.1 W1111600C for leakage every 110 working hours; replace if wear exceeds 0.12mm. Avoid using sharp tools when installing seals, as this will damage the seal lip and cause leakage.

• CA2-1-Specific Parts: Clean the Torque body CA2-1-25 W90101003 and first stage sun gear CA2-1-21 W90101009 every 150 working hours to remove dust and debris. Check the gear teeth for wear—replace if tooth wear exceeds 0.2mm to avoid power transmission failure.

• Disc Springs & Steel Balls: Inspect Disc spring B45×22.4×1.25×2.85 W05400001 for deformation every 200 working hours; replace after 10,000 compression cycles. Clean Steel ball Φ8 W29001008 every 130 working hours to ensure smooth operation.

• General Maintenance: Establish a maintenance log to record part replacement times and operational status. Follow API 5CT (11th edition) standards for regular equipment inspection, and use only matching spare parts to avoid system damage caused by mismatched components.
