Function & Pain Point Solutions

Every accessory we supply is designed to solve the real-world problems oilfield professionals face daily—problems we’ve witnessed firsthand through decades of working alongside drilling and maintenance teams. Here’s how our key products deliver tangible value:

• Hydraulic Components (BJM2-500HP2 Hydraulic Motor, KHT7625-612 Multi-way valve assembly): Eliminate hydraulic system failures that halt operations. Our BJM2-500HP2 hydraulic motor—a small, low-speed, high-torque internal meshing cycloid gear motor—delivers stable power output of 500HP, operates smoothly at 1,400 RPM, and lasts 2,300 working hours. It features an integrated output shaft and flow distribution mechanism, allowing it to work reliably under high back pressure, far longer than generic motors that typically fail after 650 hours. The KHT7625-612 multi-way valve (Parker-compatible) ensures precise hydraulic control, preventing pressure fluctuations that damage equipment.

• Sealing & Bearing Components (KHT5500-467 O-Ring 69x3.55, KHT5500-73 Aligning ball bearing 1205, XQ89/3YC needle roller 3*19.8 GB309-84): Stop leaks and bearing failures that cause downtime. Our O-rings comply with GB/T3452.1, made of high-temperature fluorine rubber that withstands 205℃ operating temperature and 25MPa pressure. The KHT5500-73 aligning ball bearing (1205 model) has an inner diameter of 25mm, outer diameter of 52mm, thickness of 15mm, rated dynamic load of 12200N, and service life of 10,000 working hours—providing reliable radial load support and reducing bearing-related jams. The 3*19.8 needle roller (GB309-84) ensures smooth rotation of XQ89/3YC main pliers, avoiding wear and jamming.

• Transmission & Gear Parts (XQ3C.Z-6 Double gear, 01.03-05M Flange gear Z=20, KHT7625-306 Motor gear): Eliminate gear jams and worn transmission parts that slow down operations. Our gears are heat-treated to HRC 62-66 hardness, ensuring smooth operation even under 34,000 N·m torque (KHT5500 rated torque). The XQ3C.Z-6 double gear is specifically designed for XQ89/3YC master pliers, ensuring precise power transmission and lasting 2,100 working hours without wear.

• Jaw & Braking Parts (KHT7625-69 Jaw set 5 1/2″, KHT5500-55 Rear Jaw Plate 3 1/2″, XYQ3C.Z-28 Brake disc): Solve slipping jaws and brake failure that compromise safety and efficiency. Our jaw sets are made of wear-resistant alloy, maintaining a secure grip even after 4,000 make-up/break-out cycles. The XYQ3C.Z-28 brake disc ensures reliable braking under 34,000 N·m torque, with a service life of 2,500 working hours—preventing brake failure that can cause accidents.

Structural Features

Our accessories are built to withstand the harshest oilfield conditions—from dusty onshore rigs to corrosive offshore platforms—with a focus on durability, ease of use, and long service life:

• Material Excellence: Transmission parts (gears, shafts, bearings) use high-strength alloy steel, while sealing components use fluorine rubber and nitrile rubber to resist oil, high temperatures, and corrosion. Fasteners like KHT7625-330 Hex bolt and KHT7625-765 Hexagon socket cap screw are made of high-carbon steel, ensuring high tensile strength and fatigue resistance for 13,000+ assembly cycles. The KHT5500-73 aligning ball bearing uses high-quality bearing steel, with a smooth surface finish to reduce friction.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.007mm—critical for components like KHT7625-425 Pin shaft (8×40) and XYQ6B motor bushing 6B.Z-56 that require a perfect fit to avoid equipment jams. This precision matches the original equipment’s specifications, eliminating the need for modification during installation, and aligns with API 7K and SY/T 5074-2012 manufacturing standards.

• User-Centric Design: Key parts like KHT7625-572 Quick coupling (2 1/8-12UN) and KHT5500-196 Adapter connector are designed for easy installation and maintenance, allowing technicians to replace parts in minutes rather than hours. The NXQ140/20Y digital control board features intuitive operation, reducing human error and ensuring precise control of XQ89/3YC power pliers.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, meeting the demands of onshore, offshore, and high-torque drilling scenarios—complying with API 7K and SY/T 5074-2012 standards for drilling and workover power tongs:

• Onshore Oilfields: Adapt to extreme temperature ranges of -52℃ to 105℃, resisting dust, sand, and heavy vibration during drilling and workover operations. Ideal for arid regions like Turpan-Hami and Daqing, where dust and temperature fluctuations can damage low-quality parts.

• Offshore Oilfields: Corrosion-resistant materials (including stainless steel fasteners and fluorine rubber seals) prevent damage from saltwater and humid air, ensuring stable performance on offshore platforms like Bohai Bay. Our O-rings and needle rollers are specially treated to resist saltwater corrosion for 2,400 working hours.

• High-Torque & Casing Operations: Suitable for deep well, horizontal well, and casing operations, where power pliers, tongs, and hydraulic motors operate under up to 34,000 N·m torque and 25MPa pressure. Our accessories are compatible with 70 801-S BV-100 Tong and BV-25 70 310 Lever long, ensuring precise make-up and break-out of casing pipes up to 14″ diameter.

• Continuous Operation: Designed for 24/7 use, our accessories reduce replacement frequency—our bearings and gear shafts can operate continuously for 10,000 working hours, while our seals and hydraulic motors last 1,900 working hours, minimizing downtime for maintenance.

Maintenance & Engineer’s Practical Tips (Avoid Costly Mistakes)

As an oilfield equipment engineer with 21 years of on-site experience, I’ve seen countless equipment failures caused by improper maintenance or using the wrong parts. Here are my practical tips to extend the life of your accessories and keep your equipment running smoothly:

• Hydraulic Motor Care: Inspect BJM2-500HP2 hydraulic motor every 420 working hours. Check for oil leaks and ensure the motor is properly lubricated with ISO VG 460 high-temperature hydraulic oil. Avoid overloading the motor beyond its 500HP rating—this can cause internal damage to the镶齿式定转子 (inserted tooth stator and rotor) and shorten its service life.

• Bearing & Needle Roller Maintenance: Apply high-temperature grease (ISO VG 460) to KHT5500-73 Aligning ball bearing 1205 and XQ89/3YC needle roller (3*19.8 GB309-84) every 230 working hours. The aligning ball bearing should be inspected for radial clearance every 6 months to ensure optimal performance—its rated dynamic load of 12200N ensures it can handle heavy loads, but proper lubrication is critical to avoid premature failure.

• Seal Inspection: Check KHT5500-467 O-Ring (69x3.55) and other sealing components every 320 working hours. Replace them if you see cracks, hardening, or oil residue—reusing old seals will lead to leaks that can damage hydraulic motors and pressure cylinders. When installing O-rings, ensure the groove is clean and free of burrs that can scratch the seal lip.

• Fastener Check: Tighten KHT7625-330 Hex bolts, KHT7625-765 Hexagon socket cap screws, and KHT7625-425 Pin shafts every 110 working hours. Loose fasteners cause vibration, which damages gear trains and jaw assemblies. Use the correct torque wrench setting—over-tightening strips threads, while under-tightening leads to loosening.

• Avoid Generic Parts: Never use generic parts as a "quick fix." For example, a generic KHT5500-73 aligning ball bearing may last only 2,800 working hours, while our GB/T276 compliant bearing lasts 10,000 working hours. Always check the part number and model compatibility before installation to avoid equipment damage and downtime.
