Product Overview: Core Components & Their Purpose

Our XYQ series spare parts cover every critical component needed to maintain and repair your equipment, from transmission parts to fasteners and seals. Below is a detailed breakdown of key products, their functions, and how they solve common operational pain points:

Key Component Descriptions

XYQ1.8Z.1-10 Open Gear: This core transmission component is designed to transfer power smoothly between moving parts, solving the common pain point of gear wear and jamming that causes equipment shutdowns. Made from high-strength alloy steel with precision machining, it resists corrosion and withstands heavy loads—our open gear has a service life of 8,500 operating hours, outperforming generic alternatives by 2,200 hours.

XYQ3C.Z 5.7 Support Seat: A critical structural component that stabilizes equipment parts, preventing vibration and misalignment. Many operators struggle with loose or cracked support seats that lead to uneven wear on other components; our support seat features a reinforced base and precise dimensional accuracy (±0.02mm) to ensure a secure fit, reducing the risk of secondary damage.

Fasteners (e.g., 3C2-36 GB/T70.1-2000 Hexagon Socket Head Screws M10X30, 3C5-2 GBT6172.1-2000 Hexagonal Thin Nut M16): These standard parts are often overlooked, but faulty fasteners cause 30% of equipment failures. Our fasteners comply with GB/T70.1-2000 and GBT6172.1-2000 standards, with a tensile strength of 8.8 grade for screws and precise thread machining to prevent loosening—even in high-vibration environments. We supply over 10,000 units monthly, with a 0.03% defect rate.

Other Critical Components: From the GB276-94 Single row deep groove ball bearing 208 (which reduces friction and extends shaft life to 12,000 hours) to the GBI235-76 O-ring 22×2.4 (providing leak-proof sealing for hydraulic systems), every part is engineered to solve specific pain points—whether it’s reducing friction, preventing leaks, or ensuring structural stability.

Structural Features

All our XYQ series parts share key structural advantages that set them apart: 1) Material selection: High-quality alloy steel, stainless steel, and nitrile rubber (for O-rings) ensure durability in harsh conditions. 2) Precision machining: CNC machining with tolerance control of ±0.01mm ensures perfect compatibility with original equipment. 3) Corrosion resistance: Electroplating and heat treatment processes protect parts from rust and wear, even in humid or chemical-rich environments. 4) Easy installation: Designed to match original part dimensions, no modifications are needed—saving maintenance time.

Applicable Working Conditions

Our XYQ series spare parts are built to perform in the toughest industrial environments, including: 1) Oil and gas fields (high pressure, high temperature, and corrosive media); 2) Heavy manufacturing plants (continuous operation, high vibration); 3) Construction sites (dust, moisture, and variable loads); 4) Mining operations (abrasive materials and extreme pressure). Whether your equipment operates at 80°C high temperatures or -20°C low temperatures, our parts maintain performance—tested to withstand temperature ranges from -40°C to 120°C and pressure up to 10MPa.

Maintenance & Engineer Tips

To maximize the life of your XYQ series parts and equipment, follow these practical maintenance tips from our senior engineers:

• For open gears (XYQ1.8Z.1-10): Apply lithium-based grease every 500 operating hours to reduce friction; check for wear monthly—if the tooth thickness wears down by 1.2mm, replace the gear immediately to avoid damaging other components.

• For fasteners: Use torque wrenches to tighten hexagon socket head screws (3C2-36 M10X30) to 45 N·m—over-tightening can strip threads, while under-tightening causes loosening. Replace fasteners every 2,000 hours to prevent fatigue failure.

• For bearings (GB276-94 208): Keep bearings clean and lubricated; replace lubricating oil every 1,000 hours. If you hear abnormal noise or feel excessive heat (above 70°C), stop equipment immediately to check for bearing damage—ignoring this can lead to shaft failure.

• Engineer’s warning: Never use generic O-rings (e.g., GBI235-76 22×2.4) as replacements—generic O-rings often have inconsistent thickness (±0.3mm vs. our ±0.05mm), leading to leaks and hydraulic system failure.
