Product Overview

Core Purpose

These spare parts are essential for the normal operation, maintenance, and repair of oilfield drilling equipment. The 1.10.01.003 Thrust Tapered Roller Bearings For Tianyi Top Drive supports the top drive’s rotating components, reducing friction and absorbing axial and radial loads—solving the problem of bearing wear and failure that often causes top drive shutdowns. The 2.4.36.003 Ball Valve G3/4 controls the flow of hydraulic oil and drilling fluid, preventing leaks and ensuring precise pressure regulation. The 1.06.17.001 Packing Assembly provides a tight seal for rotating or reciprocating components, avoiding fluid leakage that can lead to environmental pollution and equipment damage. The 2.21.70.04 Solenoid Valve controls the hydraulic system’s on-off, ensuring responsive and accurate operation of drilling mechanisms. Every part is designed to address specific operational pain points, keeping your drilling equipment running continuously and safely in harsh oilfield environments.

Function Description

Each spare part serves a unique and vital role in the drilling equipment system. The 1.10.01.003 Thrust Tapered Roller Bearings For Tianyi Top Drive features a tapered design that distributes loads evenly, with a load-bearing capacity of up to 620kN—solving the problem of bearing failure under heavy drilling loads. The 2.4.36.003 Ball Valve G3/4 has a quick-opening and closing design, allowing for fast flow control and pressure adjustment, which reduces the time needed to respond to hydraulic system issues. The 1.06.17.001 Packing Assembly is made of high-temperature resistant material, withstanding temperatures up to 120℃, preventing seal damage caused by high operating temperatures. The 3.03.02.11.016 Electrical Connector ensures stable transmission of electrical signals between equipment components, avoiding signal loss that can disrupt drilling operations. All parts work together seamlessly to maintain the integrity and efficiency of the entire drilling system.

Structural Features

Our spare parts are designed with the harsh oilfield environment in mind, boasting structural advantages that outperform standard components. The 1.10.01.003 Thrust Tapered Roller Bearings For Tianyi Top Drive uses high-quality alloy steel, with a precision-ground raceway that reduces friction and extends service life to 7,200 working hours—2,300 hours longer than ordinary bearings. The 2.4.36.003 Ball Valve G3/4 features a floating ball design and a PTFE seal, achieving an IP67 protection level and preventing dust and water intrusion, which solves the problem of valve jamming in dusty or rainy conditions. Fasteners like 4.10.02.066 Hex Head Bolts and 4.10.02.024 Hexagon Bolts undergo hot-dip galvanization, resisting corrosion from saltwater and oilfield chemicals. The 1.01.20.002 Wear Sleeve is made of wear-resistant alloy, with a surface hardness of HRC 60, reducing wear from constant friction and extending the service life of the components it protects.

Applicable Working Conditions

These spare parts are widely suitable for various oilfield scenarios, including onshore oilfields (Liaohe Oilfield, Permian Basin), offshore oil platforms (North Sea, Gulf of Mexico), and desert oilfields (Gobi Oilfield, Kazakhstan). They can withstand extreme temperatures ranging from -45℃ to 95℃, adapt to high humidity (up to 98%), high vibration (frequency 12-55Hz), and high-pressure environments (up to 45MPa). Whether for ultra-deep well drilling (depth up to 7,500 meters), horizontal drilling, or workover operations, our parts maintain stable performance—solving the problem of poor adaptability of ordinary spare parts to harsh conditions. They are fully compatible with Tianyi Top Drive models (DQ40-LHTY to DQ90-LHTY) and ZJ series drilling rigs, eliminating the hassle of finding mismatched components and ensuring quick replacement.

Maintenance and Care Recommendations

To extend the service life of our spare parts and ensure equipment stability, our engineers offer practical, on-site maintenance advice. For the 1.10.01.003 Thrust Tapered Roller Bearings For Tianyi Top Drive, apply high-temperature lubricating grease every 400 working hours, check for abnormal noise or temperature rise regularly, and replace the bearings if there is any sign of wear—this prevents sudden bearing failure during drilling. For the 2.4.36.003 Ball Valve G3/4, clean the valve core every 600 working hours, inspect the seal for damage, and avoid over-tightening the valve handle, as this can damage the valve stem. A key engineer tip: never mix different types of O-ring seals (like 2.4.51.901 O-ring seal and 2.4.99.03.004 Y-ring for piston), as this can cause leaks and hydraulic system failure. The 1.06.17.001 Packing Assembly should be replaced every 1,800 working hours, even if there is no visible damage, to prevent sudden leaks. Our team also provides on-site maintenance training to help your team master these skills and avoid common mistakes.
