Product Overview & Core Functions

Core Purpose

Our oilfield spare parts are designed to protect the integrity and efficiency of critical oilfield equipment, directly resolving downtime caused by component wear, fluid leakage, electrical malfunctions, and mechanical failure. The 661009010 inner bearing (Mission 10×8×14 pump) reduces friction in the pump’s rotating components, preventing overheating and flow rate loss that disrupt drilling fluid circulation. The 311489 steel pin (Weatherford Hydraulic Tong) secures the tong’s jaw mechanism, maintaining consistent torque during tubular make-up and breakout to avoid thread damage. The 112809-06 cap (NOV TDS Hydraulic Jack) protects the jack’s hydraulic port from debris and contamination, preventing internal component damage. The 6SY7010-0AB66 thyristor module ensures stable electrical control for drilling systems, avoiding power surges that shut down operations. Collectively, these parts extend equipment service life by 5300+ working hours on average, reduce unplanned downtime by 98 hours annually, and help oilfield enterprises cut maintenance costs while ensuring operational safety and compliance with industry regulations—critical for meeting demanding production targets.

Functional Description

Each spare part is tailored to solve specific industry challenges, with practical functions that address real-world pain points: The 661009010 inner bearing (Mission 10×8×14 pump) enables smooth rotation of the pump shaft, withstanding high pressure and abrasive mud to prevent flow rate loss—critical for maintaining consistent drilling fluid circulation. The 311489 pin (Weatherford Hydraulic Tong) is a high-strength steel component that locks the tong’s moving parts, transmitting up to 15,000 ft-lb torque without bending or breaking, ensuring secure tubular grip. The 112809-06 cap (NOV TDS Hydraulic Jack) is a threaded plastic cap that seals the jack’s hydraulic port, keeping out dirt, mud, and moisture that cause corrosion and hydraulic system failures. The 6SY7010-0AB66 thyristor module regulates electrical current for drilling control systems, preventing power fluctuations that lead to equipment shutdowns. The SB56J0039 clamp assembly (XBSY SV5 pump) secures pump components, preventing vibration-induced damage and fluid leakage.

Maintenance & Practical Tips

Based on years of on-site maintenance experience, our engineers provide practical, easy-to-follow tips to maximize the service life of our spare parts and avoid common pitfalls that lead to premature failure: For the 661009010 inner bearing (Mission 10×8×14 pump), lubricate with EP2 lithium grease every 300 working hours; inspect for abnormal noise or overheating, and replace if the bearing clearance exceeds 0.2mm. For the 311489 pin (Weatherford Hydraulic Tong), check for wear or bending every 200 working hours; replace if any deformation is found, and apply anti-seize compound during installation to prevent rust. For the 112809-06 cap (NOV TDS Hydraulic Jack), inspect the thread for damage every 150 working hours; replace if the cap no longer seals tightly, and clean the hydraulic port before reinstalling. For the 6SY7010-0AB66 thyristor module, keep the heat sink clean to prevent overheating; check electrical connections every 250 working hours, and replace if there is any loose wiring. For O-rings like 51300-381-B, store in a cool, dry place away from UV light; replace every 6 months or if any cracks are found.

Engineer’s Reminder: Never reuse worn bearings or seals, as they can lead to costly equipment damage and downtime. Always use parts that match the original equipment’s specifications—for example, the 661009010 inner bearing is specifically designed for Mission 10×8×14 pumps, and using a mismatched bearing will cause pump failure. Additionally, follow API 6A standards when installing wellhead-related parts (like valve seats and unions) to ensure safety and compliance. Regularly clean and inspect parts exposed to abrasive mud, such as the 4P100238 bronze bushing, to prevent premature wear.
