Usage Notes
1
Before using the roller, carefully inspect the appearance for any serious scratches or damage. The rotating roller should rotate flexibly without any jamming.
2
The installation distance of the rollers should be scientifically calculated based on the type of logistics and the characteristics of the conveyor, to avoid installation that is too loose or too dense.
3
The installation of rollers should be adapted to avoid mutual friction and collision.
Maintenance
1
The normal service life of the roller is over 20000 hours and generally does not require maintenance. However, according to the usage location and the size of the load, corresponding maintenance dates should be set, and timely cleaning and oil injection maintenance should be carried out, as well as timely cleaning of floating coal, etc. Replace the rollers with abnormal noise and non rotation in a timely manner.
2
When replacing the bearing, the opening of the bearing cage must be outward. After the bearing is installed into the roller, it should maintain appropriate clearance and not be crushed.
3
Maze seals should be made of original accessories and should be installed separately into the rollers during assembly, and should not be assembled together.
4
When using the idler, precautions should be taken to prevent heavy objects from hitting the idler tube.
5
To ensure the sealing performance and usability of the rollers, it is prohibited to disassemble the rollers at will.

What materials are used in the manufacturing of these rollers?
The tube is made of high-quality Q235 steel, and the shaft is engineered with durable 45# steel. They feature single or double row deep groove ball bearings (2RZ & 2Z with C3 clearance) and mixed gas shielded arc welding ends for maximum structural reliability.
What is the standard expected service life of the rollers?
Under normal operating conditions, the service life of these rollers exceeds 20,000 hours, generally requiring minimal maintenance during continuous operation.
Can the rollers and idlers be customized?
Yes, we can manufacture rollers and idlers tailored according to specific buyer requirements, dimensions, surface treatments, and conveyor configurations.
What surface finishing options are available?
Multiple surface treatment and painting options are offered, including ordinary painting, hot galvanized painting, electrostatic spray painting, and baked painting for optimal corrosion and wear protection.
What precautions should be observed when replacing roller bearings?
When replacing the bearing, ensure the opening of the bearing cage faces outward. Once installed inside the roller, proper clearance must be maintained to prevent the bearing from being crushed.
