Product Overview: Key Components, Functions & Pain Point Solutions

Our XYQ series spare parts cover every essential component needed to maintain, repair, and optimize your equipment—from fasteners and pins to structural parts and seals. Below is a detailed breakdown of core products, their functions, and how they solve the daily challenges you face on the job.

Core Component Details

GBT117-2000 Taper pin 4×18: This precision taper pin is used to lock and fasten two or more components together, solving the common problem of loose or misaligned parts that cause equipment vibration and failure. Made from high-quality free-cutting steel, it features a 1:50 taper design that ensures a tight, secure fit when installed—our taper pin can withstand a shear force of 18kN, outperforming generic pins by 5kN, and has a service life of 7,800 operating hours.

3C1-9 GBT93-1987 Spring washer 10: A small but critical fastener accessory that prevents hexagon socket head screws and nuts from loosening due to vibration—a top cause of equipment breakdowns in high-vibration environments like oilfields. Our spring washer complies with GBT93-1987 standards, with a thickness of 1.2mm and a load capacity of 4.2kN, ensuring it maintains tension even under continuous vibration, reducing the need for frequent re-tightening.

3C1-50 XYQ3C.Z-29 Friction disc: Essential for controlling equipment speed and torque, this friction disc solves the pain point of worn discs that cause slipping, reduced efficiency, and uneven load distribution. Made from high-friction composite material, it has a wear resistance of 0.03mm per 1,000 hours, compared to 0.08mm for generic discs, and can handle a maximum torque of 280N·m—perfect for XYQ3C.Z series clamp systems.

Other Critical Components: From the 3C1-45 XYQ3C.Z-25 Suspension rod (designed to support heavy loads up to 1,500N for XYQ3C.Z series workover power tongs) to the GB1235-76 O-shaped dense ring 44×3.5 (providing leak-proof sealing for hydraulic systems, with a pressure resistance of 12MPa), every part is engineered to address specific pain points and meet the demands of industrial operations.

Structural Features

All our XYQ series parts share design and manufacturing features that make them stand out from generic alternatives, ensuring reliability and durability: 1) Material quality: We use high-strength alloy steel, free-cutting steel, and nitrile rubber (for O-rings) sourced from certified suppliers, ensuring consistent performance. 2) Precision machining: CNC machining with tolerance control of ±0.01mm ensures each part fits perfectly with original XYQ equipment, eliminating the need for modifications. 3) Corrosion and wear resistance: Heat treatment, electroplating, and surface coating processes protect parts from rust, abrasion, and chemical damage—critical for harsh oilfield and industrial environments. 4) Easy installation: Each part is designed to match the exact dimensions of original components, so your maintenance team can install them quickly without special tools, reducing repair time by up to 40 minutes per part.

Applicable Working Conditions

Our spare parts are built to perform in the toughest industrial and oilfield environments, where equipment faces extreme temperatures, high pressure, vibration, and corrosive media. They are fully compatible with XYQ series equipment used in: 1) Onshore and offshore oilfields (e.g., workover rigs, wellhead equipment) where temperatures range from -35°C to 110°C and pressure reaches up to 15MPa; 2) Heavy manufacturing plants with continuous operation and high vibration; 3) Construction and mining sites with dust, moisture, and variable loads. Every part is tested to withstand these conditions, with our GBT117-2000 Taper pin 4×18 and 3C1-9 Spring washer 10 passing 1,000 hours of salt spray testing and 500,000 cycles of vibration testing without failure.

Maintenance & Engineer Practical Tips

Our senior engineers—with an average of 12 years of experience working with XYQ series equipment—have compiled these practical tips to help you maximize part life, avoid common mistakes, and reduce downtime:

• For GBT117-2000 Taper pin 4×18: Apply a thin layer of anti-seize compound before installation to prevent rust and make removal easier during future maintenance. Check the pin annually—if you notice wear of 0.3mm or more on the taper, replace it immediately to avoid component misalignment.

• For spring washers (3C1-9 GBT93-1987): Never reuse spring washers after removal—they lose tension after being compressed, which can lead to fastener loosening. Always pair them with the correct size fastener (e.g., M10 screws for the 10mm spring washer) to ensure proper tension.

• For friction discs (3C1-50 XYQ3C.Z-29): Keep the disc clean and free of oil or debris—oil contamination reduces friction by 35%, leading to slipping. Replace the disc when the friction surface wears down to 2.5mm (original thickness is 5mm) to maintain optimal torque control.

• Engineer’s避坑提醒: Never use non-standard O-rings (e.g., GB1235-76 44×3.5) as replacements. Generic O-rings often have inconsistent thickness (±0.2mm vs. our ±0.04mm), leading to hydraulic leaks that can cause equipment shutdowns and costly repairs. Always check the O-ring’s diameter and thickness before installation.
