2. Complete Product Introduction

This supporting product portfolio includes full-range wearable and core load-bearing parts for drilling rigs, covering XJ40C series shaft sleeves, bearings, positioning pins and adjusting fasteners, JC28 series balance adjusting rods, connecting discs, bearing covers and transmission shafts, and JC32B series swing arms and adjusting nuts. It is also equipped with ATD230H friction components, standard spring washers, various specification bolts and sealing rings, pipeline connectors and top restoration system accessories. Every part adopts precision CNC machining and high-strength alloy forging technology, with unified assembly tolerance standards and high interchangeability, fully matching XJ40C drilling rigs and JC28/JC32B supporting mechanical systems to support one-stop equipment maintenance and part replacement.

3. Core Functional Description

3.1 Balanced Braking & Positioning Control

JC28F cast brake blocks and ATD230H friction assemblies cooperate with JC32B adjusting nuts and XJ40C positioning fasteners to form a high-precision braking control system. This structure effectively solves the pain point of unbalanced braking torque and offset operation caused by long-term friction loss, ensuring stable and accurate braking action of drilling rigs under variable load working conditions.

3.2 Stable Transmission & Structural Support

Custom transmission shafts, chain gears, key blocks and bearing components form a complete power transmission and structural support system. It offsets mechanical vibration and assembly gap errors generated during equipment operation, eliminating power attenuation and operational jitter faults of drilling rig transmission structures in high-frequency start-stop cycles.

3.3 Sealing & Pipeline Stable Transmission

Multi-specification oil seals, gaskets and Z-specification pipeline joints achieve fully sealed connection of hydraulic and pneumatic pipelines. They block external dust and moisture invasion while preventing medium seepage and pipeline pressure loss, maintaining stable operating pressure of drilling rig hydraulic and control systems in harsh field environments.

4. Structural Characteristics

All accessories adopt modular integrated structural design with unified assembly benchmarks, realizing rapid disassembly and on-site replacement without secondary calibration. Core load-bearing parts adopt integral forging molding technology, featuring high structural rigidity and strong anti-fatigue performance. The matched balance base and adjusting gaskets support micro-precision gap adjustment, while spring washers and special positioning pins effectively prevent structural loosening caused by long-term vibration. The optimized lubricating disc and oil throwing disc structure reduces internal friction of equipment and prolongs the service cycle of transmission components.

5. Applicable Working Conditions

This series of accessories is exclusively applicable to XJ40C drilling rigs and matched JC28/JC32B mechanical supporting systems, adapting to full-cycle onshore oilfield drilling, well repair and heavy-load hoisting operation scenarios. It can stably work in open-air environments with temperatures ranging from -20℃ to 62℃, high dust and strong vibration, and maintains consistent mechanical performance under long-term intermittent heavy-load and continuous cyclic operation states.

6. Engineer On-site Maintenance & Avoidance Suggestions

Summarized from years of oilfield on-site maintenance experience, friction assemblies and brake components need wear inspection every 3 months and overall replacement every 10 months to avoid braking performance degradation. Transmission bearings and key blocks require regular lubrication replenishment to reduce dry friction loss. Pipeline sealing parts should be replaced regularly to prevent aging and seepage. It is not allowed to use mismatched adjusting gaskets and fasteners, which will cause equipment operation deviation. Standardized maintenance can extend the continuous stable operation time of matching equipment by 2100 working hours compared with casual maintenance modes.
