Function and Action
Core Functions: As a key component of the Komatsu grader's transmission system, it undertakes three core responsibilities:
Supporting Rotating Parts: Providing stable support for the grader's transmission components, ensuring the coaxiality of all rotating parts, and reducing vibration and noise.
Transmitting Torque and Power:Transmitting the engine's power output to the working device and walking system, enabling the grader's propulsion and scraping operations.
Bearing Combined Loads:Bearing the combined effects of bending moment, torque, and axial force during grader operation, ensuring the overall stability of the machine.
Specific application scenarios
Connects the gearbox and drive axle to transmit power.
Supports rotating components of working devices (such as scrapers and rippers).
Transmits steering torque in the steering system to ensure precise operation.
Product superiority

It can withstand torque up to 18,000 N·m and axial loads up to 8,500 N, suitable for high-intensity operations.
It adapts to extreme conditions: maintaining stable performance in high-temperature (+80℃), low-temperature (-40℃), and high-dust environments, reducing the failure rate by 60%.
3.Convenience and Economy of Maintenance
Standardized design facilitates disassembly and maintenance, reducing repair time by 50%.
High compatibility with other Komatsu parts lowers repair costs.
Original manufacturer quality assurance reduces replacement frequency, lowering total cost of ownership by 30%.
Installation and Maintenance Recommendations
1.Installation Points
Thoroughly clean the journal and mating surfaces before installation, ensuring they are free of oil and impurities.
Use specialized tools to install the bearing; never strike the shaft surface to prevent damage.
Tighten the connecting bolts to the specified torque (35-40 N·m) to ensure a precise fit.
After installation, check for smooth rotation to ensure there is no jamming.
2.Maintenance suggestion
Routine Inspection: Before each operation, check the shaft lubrication and for any abnormal wear.
Regular Maintenance: Replenish with high-temperature grease every 250 working hours.
Comprehensive Inspection: Conduct a comprehensive inspection every 1000 working hours, measuring the dimensions of critical components.
If abnormal vibration or noise is detected, immediately stop the machine and inspect to prevent further damage.
