What is a roller bearing?

Nowadays, the general rollers use (large clearance) deep groove ball bearings, while the bearings used to be nylon ball frames. If it is an oil filled roller, 

it usually uses tapered roller bearings. The bearings used for the rollers are all standard bearings.

Roller bearings are components used in conveyor systems to support and rotate conveyor belts, and their performance directly affects the operational 

efficiency and stability of the conveyor. There are various types of roller bearings, including deep groove ball bearings, cylindrical roller bearings, and 

long-life ball bearings.Type and Characteristics

Deep groove ball bearings: With a simple structure, strong load-bearing capacity, and smooth operation, they are suitable for medium and low-speed, 

medium and light load applications and can meet the operational needs of most conveyors.

Cylindrical roller bearings: have higher load-bearing capacity and impact resistance, suitable for high-speed and heavy-duty conveyor systems, but have 

higher maintenance costs and higher requirements for installation accuracy.

Long life ball bearings: Known for their excellent durability and longevity, they are suitable for applications that require high bearing life, such as high-

speed elevators, automated production lines, etc. Despite their high price, they can significantly reduce maintenance costs during long-term operation.

Material and craftsmanship

The roller bearings are made of thick material bearing steel and undergo multiple processes such as rough grinding, fine grinding, and ultra precision 

processing, resulting in deep and bright grooves. Compared with ordinary bearings, roller bearings have deeper grooves, better coordination between 

steel balls and grooves, longer service life, and lower operating noise. In addition, roller bearings have good temperature resistance and wear resistance, 

and can maintain hardness over a wide temperature range, making them suitable for various harsh environments.
