Several using conditions causes the different abrasion limits and use time

　　Some people may find that even through the total installation time for these two caterpillar bucket teeth pins are in the same day, but their using limits and use time are has a very big difference at the end, writer said there are several different using conditions had causes this phenomenon happen, such as these two caterpillar bucket teeth pins had suffer the different loads during the normal working period, and the temperature and turning speed for the working conditions is different too, so their final abrasion and friction degrees would be different as well, and causes the different abrasion limits and total use life.

　　Under the normal situation, if the total use life for caterpillar bucket teeth pins can’t be guarantee the half for its guarantee service life, during the small repair and maintenance period, users need to replace this caterpillar bucket teeth pins timely, because it belongs to the easily damage and consume part; but if its use life can above half of its service life, we can regard it as non-easily damage part.
