KOMATSU PC20 Track Chain Assembly with Mid-Frequency Heat-Treatment Technology Self-Lubricated System and Precision Assembly Dimensions
Utilizing sophisticated machining centers, including horizontal and vertical CNC technology, we perform precision operations like cutting, boring, tapping, and grinding to guarantee component quality and accuracy. This ensures precise assembly dimensions while extending component lifespan and minimizing hourly production expenses.
Track links are manufactured from 35 MNB forged special steel, reinforced with advanced structure technology and heat treatment processes. This combination delivers maximum strength and abrasion resistance. The integrated self-lubricated system significantly enhances track chain bearing service life.
