Production description
Crane track roller is composition of two pieces of forged semi-roller and the roller body is welded by CO2 automatic welding.
We will select different material as per different working condition for our crane track rollers to meet customer requirements and machine precisely and assemble them well to guarantee the hight quality.
In the process of assembly of roller, the expected and reliable sealing and lubricating rotation of roller are guaranteed by testing of air pressure tightness and load-bearing rotation.

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.
