Side cover
Metal material has a high degree of internal spheroidization and good impact resistance, which reduces the likelihood of a side cover due to an external blow.
Sealing system
The floating seal system is used to prevent a decrease in the internal lubricant of the support roller due to oil leakage, as well as to prevent damage caused by wear between the shaft and the sleeve.
Improving the design
(This item refers only to the original details 5A) The support rollers of the model 5A have a unique design that prevents the accumulation of sand, which reduces the risk of abnormal wear between the support rollers and the caterpillar chain caused by the soil and sand. accumulation; and the plug for filling the oil is changed from the original bilateral to one -sided; 4 holes for filling the oil on the housing of the support wheel are canceled, and a D-shaped groove is designed from the shaft side.
