Industry information
Conveyor roller generally consists of four important components, including bearing, accessories, seals, and bearing housing.
1.Roller Bearing: Bearing is an important part of the roller and the quality of the bearings directly affects the service life of the roller. Therefore, when choosing roller bearing, it is important to be more cautious than choosing other roller accessories.
2.Roller Accessories: Roller accessories mainly include roller bracket, spacer sleeve, hook connector, cast steel rake, cylindrical pin, roller shaft, and cirlip ring.
3.Roller Seals: Roller seals are made of polyethylene and nylon. Polyethylene has a lower cost but relatively poor performance, while nylon seals have a higher cost but better performance. To identify whether it is a nylon seal, you can put the seal in water, and the one that sinks is a nylon seal, while the one that floats on the water surface is a polyethylene seal.
4.Stamped Bearing Housing: Roller bearing housing are divided into two types, stamped bearing housing and cast iron (gray iron) bearing housing. Stamped bearing housing is mostly welded to steel pipes, while cast iron bearing housing is extruded onto steel pipes. The characteristics of stamped bearing housing is good sealing and strong overall load-bearing capacity, while the main characteristic of cast iron bearing housing is high concentricity but lower load-bearing capacity compared to stamped bearing housing.
