Product Introduction
Track Roller kh040
Production description
Digger track rollers also called digger bottom rollers and digger lower rollers are used to support the weight of crawler excavators and roll on the track link. It is also used to keep track link to prevent it from lateral slippage. When the excavator steers, mini excavator bottom roller force the track assy to skip on the ground.
They are often in mud, water and just and bear strong impact. Therefore,they are required to be sealed reliably and wear-resisitant.

FAQ
1. What is the delivery time?
Generally speaking, the delivery time is 20days to 45days.it depend on how many items for a order. But if the whole order are 200 serial track roller(bottom roller, lower roller), the delivery time is within 10days.
2. What is MOQ for the order?
Generally speaking, the MOQ is a full container load of 20 feet container. Under this condition, the single cost can be lowered. if customers ask for less full container load. It is also acceptable.
3. How can you control your quality?
When material come inside our factory, we need to analyze the material cost. And when front idlers and sprocket rims material are casted. We need to analyze the composition to see if the material is qualified or not. When track rollers, carrier rollers and front idlers are being assembled, we need to oil leakage testing. After several parts are heat treated, we need to check the hardness before all are done.And our inspectors will check the sizes at ramdom when parts are being machined or assembled. All of these can guarantee the parts with correct sizes and good quality.
