Designed specifically for field maintenance technicians, industrial equipment procurement teams and mechanical overhaul departments, the product set meets dual core demands of standardized equipment assembly replacement and on-site technical fault troubleshooting, providing reliable structural and hydraulic support for industrial heavy machinery continuous operation.

2. Product Overview

The product portfolio covers custom core components such as JC153 transmission shafts, chain wheels, end plugs, bearing covers and auxiliary drive assemblies, JC054 shaft sleeves, splines and sealing parts, matched with GB/T standard bolts, nuts, washers and cotter pins. It also includes supporting accessories like self-sealing quick connectors, oil filter assemblies, disc brake pressure sensors and gas release valve fittings. All parts comply with national GB mechanical standards and industrial mechanical design specifications. Exclusive batch test data verifies that the complete matching assembly can maintain stable mechanical performance for 8500 consecutive working hours under rated load. All finished parts adopt precision turning and integral forging processes, with assembly tolerance controlled within 0.02mm, ensuring high matching accuracy and interchangeability for target equipment.

3. Key Functional Description

This series of fittings undertakes multiple core operational functions for industrial heavy machinery. It realizes stable power transmission through drive shafts, chain wheels and spline sets to avoid power attenuation and transmission lag. It ensures overall structural fastening and anti-vibration positioning via matched standard bolts, spring washers and lock nuts. It achieves full-range sealing protection through O-rings and gaskets to block lubricant leakage and external dust invasion. It stabilizes brake system operating pressure with disc brake pressure sensors and control valves. It completes quick hydraulic circuit connection and pressure maintenance through self-sealing quick connectors, and guarantees clean lubrication circulation relying on high-precision oil filter components.

4. Structural Characteristics

All components adopt practical modular integrated structure, supporting tool-free quick disassembly and on-site replacement to shorten equipment downtime. Transmission splines and chain wheels adopt optimized tooth profile design, effectively reducing friction loss during high-speed operation. Self-sealing quick connectors feature one-piece sealing structure, eliminating hidden leakage risks of traditional threaded joints. Standard fasteners and custom JC series parts achieve full-size universal matching without secondary processing. The oil splashing ring and lubrication assembly adopt directional oil supply structure to improve internal component lubrication uniformity. Protective covers and end plug parts enhance equipment dustproof and anti-collision performance, adapting to harsh industrial working environments.

5. Applicable Working Conditions

This product suite is suitable for large mining transmission machinery, oilfield drilling and production operating equipment and heavy industrial disc brake devices. It stably adapts to working temperature range from -28℃ to 132℃ and long-term alternating load impact working state. It can operate continuously in high-dust, high-humidity and slight vibration industrial scenarios, fully meeting equipment daily operation, regular maintenance, component renewal and fault emergency repair demands of transmission systems and brake systems.

6. Professional Maintenance & Engineer Practical Tips

Based on field maintenance experience, check the fastening tightness of all GB standard fasteners every 12 working days to prevent fatigue loosening caused by long-term vibration. Inspect the wear degree of splines and transmission chain wheels every 30 working days, and replace parts with excessive wear in time. Clean and replace oil filter components regularly to ensure unobstructed lubricating oil circuit. Check the elasticity and sealing performance of O-rings and gaskets every six months of continuous operation. Avoid over-tightening threaded fasteners during assembly to prevent thread damage, which can effectively extend the overall service life of equipment accessories.
