1. Product Overview
569-27-61912 tapered roller bearing is a high-quality replacement part specially developed for Komatsu HD465-7 and HD605-7 mining dump trucks. Manufactured in strict accordance with OEM size and process standards, it is mainly installed on the core positions of mining truck axles and final drive travel systems. It is designed to cope with complex mining conditions such as heavy-load transportation, bumpy roads and high-frequency start-stop operation, effectively bearing composite impact force and stabilizing the transmission structure. It is an essential core part for vehicle maintenance and overhaul.
2. Material & Technical Advantages
Made of industrial-grade GCr15 high-carbon chromium bearing steel, the product adopts precise quenching and tempering heat treatment technology. The rollers and raceways feature uniform hardness and stable metallographic structure, providing excellent wear resistance, fatigue resistance and impact resistance. The unique tapered structure can bear both radial pressure and axial thrust, perfectly matching the composite force characteristics of mining truck travel mechanisms, effectively avoiding looseness, abnormal noise and jamming. The split structure enables easy installation and disassembly, greatly reducing maintenance time and shutdown loss.
3. Multiple Precision Grade Options
P0 Grade: Standard universal precision with high cost performance, suitable for daily mining transportation and routine maintenance replacement.
P6 Grade: Precision tolerance with low vibration and low heat generation, ensuring stable operation for long-hour and high-frequency heavy-duty mining transportation.
P5 Grade: High-precision industrial grade, ideal for complete vehicle overhaul and performance upgrade, featuring higher operation accuracy, better stability and longer service life.
4. Quality & Installation Guarantee
All bearings are strictly manufactured according to the original 569-27-61912 specifications, supporting direct replacement without secondary processing. Every product undergoes strict factory inspection including clearance test, hardness test and appearance inspection. Custom precision grades are available for bulk orders. With stable quality and low failure rate, it effectively reduces later equipment maintenance costs.
5. Application Scenarios
Widely used for complete overhaul and daily fleet maintenance of Komatsu HD465-7 & HD605-7 mining dump trucks, as well as export wholesale of mining machinery spare parts. It solves common bearing problems such as wear looseness, running noise, axial play, insufficient load capacity and transmission jitter.
