Trade Information

1. Product Overview

The 714-12-19380 deep groove ball bearing is manufactured strictly to Komatsu OEM standards, specially used for core transmission parts such as gearboxes and transfer cases of D155 and D275A-5 bulldozers. It can stably buffer alternating loads generated during bulldozing and climbing work. With strong structural versatility and easy disassembly, it is a high-demand OEM-equivalent wearable part in the construction machinery repair market.

2. Material & Processing Advantages

Made of national standard GCr15 high-carbon chromium bearing steel with professional quenching and tempering heat treatment, it features uniform hardness and stable metallographic structure for steel balls and inner/outer ring raceways, delivering excellent anti-fatigue and anti-rust performance. The integrated deep groove structure adapts to bidirectional axial stress, with low friction and controllable temperature rise at high speed to avoid jamming and abnormal noise. Super-finish grinding on raceways ensures high surface finish, greatly extending service life in dusty construction sites.

3. Precision Grade Selection Guide

P0: Standard general precision with high cost performance, meeting basic needs of regular earthwork construction and daily maintenance replacement
P6: Tighter dimensional tolerance reduces vibration and heat generation, suitable for long-hour heavy-duty continuous mining operation
P5: High-precision grade for transmission overhaul and machine performance upgrade, offering better concentricity and stronger high-speed running stability

4. Quality Control & Installation Tips

Every product passes full inspections on clearance, hardness, dimensional accuracy and appearance defects before delivery. The complete structure allows direct installation without secondary machining, and customized precision grades are available for bulk orders. Clean impurities in the transmission cavity, fill matched grease and set proper preload during installation to reduce wear and extend service life.

5. Application Scenarios

It is widely applied to gearbox repair of Komatsu D155 & D275A-5 bulldozers, export wholesale of construction machinery spare parts and regular maintenance of engineering fleets. It solves common failures of original bearings including abnormal noise, transmission shake, excessive temperature rise, loose clearance and reduced power transmission efficiency.
