Product Introduction

We supply a complete line of high-strength, wear-resistant oilfield drilling spare parts, covering bakelite beads, pinion shafts, sealing rings, brake belt assemblies, bearing components, hydraulic fittings, packing sets, and other core accessories, with core models including 3660-02-30 bakelite bead, NB800M series pinion shafts and baffle plates, M15-1002-01B hydraulic components, AY11000 brake actuator assemblies, and 352944 high-load bearings. Each part is produced with premium industrial raw materials and precision machining technology, backed by mature oilfield equipment parts manufacturing experience and strict quality inspection system, with full compliance with international petroleum machinery certification requirements.

We have carried out 8 rounds of full-load fatigue testing on all key transmission and sealing parts, and the continuous safe operation time of core wearing parts reaches 1900 working hours, which is 720 hours longer than that of ordinary aftermarket parts on the market. Every part leaving the factory has complete size inspection reports and load test data, truly realizing direct replacement with original parts, eliminating the need for secondary modification and on-site polishing, and greatly reducing the workload of on-site maintenance personnel.

Function Description

Each spare part has a clear functional positioning, aiming to stabilize equipment operation and block common fault risks: bakelite bead 3660-02-30 plays a buffer and isolation role in the transmission structure, avoiding rigid friction between metal components and reducing abnormal noise and wear; NB800M.03.02A hobbing pinion shaft undertakes core power transmission, ensuring stable torque output under heavy load and no skidding or deformation during high-intensity operation; 51300-348-FO sealing ring fits perfectly with 3-inch bore wash pipe, sealing drilling fluid and lubricating oil, completely preventing external dust and mud from entering the equipment interior.

PZ03040600002AA brake belt assembly is dedicated to SJ Petro XJ450T sand drum, providing stable braking force, avoiding brake failure under heavy load and ensuring operational safety; 4500100044 352944 bearings bear radial and axial composite loads, reducing rotational friction and preventing eccentric wear of transmission components; brake caliper M16-1000-010 and AY11000 brake actuator work together to realize sensitive and stable braking response; all sealing, packing and mechanical seal parts effectively prevent fluid leakage, avoiding material waste and environmental pollution caused by leakage.

Structural Features

All spare parts adopt precision machining and molding processes, with dimensional tolerance controlled within 0.01mm, fully matching the installation space and connection size of original equipment. Transmission shafts such as pinion shaft and gear shaft adopt integral forging and precision hobbing processes, with uniform gear meshing, high surface finish, and no hidden cracks inside; brake belt assembly uses high-strength steel strap structure, with strong tensile resistance and stable friction performance, not easy to deform after long-term use.

Sealing parts are made of high-elasticity, corrosion-resistant composite rubber and wear-resistant bakelite materials, with seamless fitting structure and strong adaptability to equipment motion tracks; bearing components have built-in reinforced retainers, with uniform stress distribution and strong impact resistance; fasteners, cotter pins and retaining rings adopt precision stamping and heat treatment processes, with high tensile strength and fatigue resistance, not easy to loosen or break under strong vibration; hydraulic fittings and connectors adopt standard JIC interface design, with good universality and tight connection, no oil leakage under high pressure.

Applicable Working Conditions

These spare parts are suitable for harsh working environments of land drilling rigs, desert oilfields, and offshore workover platforms, adapting to high-intensity continuous operation, strong vibration, heavy load, mud erosion, and slight corrosive medium contact conditions. They can work stably in the ambient temperature range of -35℃ to 120℃, matching the full-cycle operation requirements of SJ Petro XJ450T sand drum, TWS-600S pump, ZQ203-100 transmission assembly, VARCO well control tools and other equipment.

Applicable working scenarios include well drilling operation, sand pumping construction, well control maintenance, pump set transmission, and drilling fluid transportation; they can withstand high-pressure hydraulic impact, heavy-load torque transmission, and long-term continuous rotation, perfectly adapting to the harsh construction requirements of oilfield field operations, and are not prone to performance degradation or failure even in extreme construction environments.

Maintenance & Care Suggestions

1. For transmission components such as pinion shaft NB800M.03.02A and gear shaft, conduct surface wear and gear meshing inspection every 850 working hours, and replace parts immediately if wear, crack or tooth breakage is found, to avoid greater damage to the entire transmission system.

2. Regularly check the tightness of sealing rings, packing sets and mechanical seals, and replace aging and deformed sealing parts in a timely manner; when replacing, clean the installation groove thoroughly to avoid residual impurities affecting the sealing effect, and do not use unqualified sealing accessories of different materials at will.

3. Bearing parts need regular quantitative lubrication, using special high-temperature resistant and anti-wear lubricating grease for oilfield equipment; do not mix different types of lubricants, and check for abnormal noise or jamming during operation, which indicates bearing wear and needs replacement.

4. Brake belt assembly and brake caliper components should check the friction surface wear and connection tightness regularly, adjust the braking clearance in time, and avoid brake delay or failure caused by excessive wear; keep the friction surface clean and free of oil stains to ensure braking stability.

5. Store spare parts in a dry, ventilated and dust-free environment, avoid direct sunlight and heavy pressure, especially rubber sealing parts and bakelite parts, to prevent aging, deformation and cracking, and ensure the performance of spare parts during installation.
