Carbon Steel Conveyor Return Roller 190mm Spiral Conveyor Rollers
Carbon Steel Disc Roller Rubber Return Comb Idler For Conveyor
The comb-shaped roller is suitable for conveyors in the industry. The comb-shaped roller can replace the previous metal rollers and nylon plastic rollers. It has long service life, convenient installation, stable self-defined conveying, reducing conveyor belt deviation and protecting conveyor belts. The comb-shaped roller has better performance than traditional iron rollers, with low wear coefficient, small specific gravity, light weight, easy replacement, low noise, stable operation, suitable for working environments with harsh production conditions, and long service life.
Conveyors Rubber Disc Return Idlers operate by utilising durable rubber discs positioned at regular intervals along the roller to effectively eliminate conveyor belt carry back build up.This is done by breaking up the material on the return side of the conveyor belt which is normally concentrated in the centre of the belt.Rubber Disc Return Roller JoyrollThe rubber discs avoid the build up of material that can be deposited onto the roller surface which can cause the roller diameter to develop an irregular worn surface and change shape.This is often a major cause of belt mistracking. rubber disc roller are a reliable and simple maintenance solution to this common belt conveyor problem.Rollers,Idler Frames Structure Rollers Idler Frames Structure Quality Rollers built-to-last Steel rollers - three feature levels available.
The seal of the roller can be divided into steel and plastic. Their seals are filled with grease inside. The quality of the roller directly affects the power consumption of the belt conveyor and the life of the belt. Therefore, reliable dust-proof sealing and good lubrication are important standards for use.
There are five other criteria for judging the quality of rollers:
1. Dustproof performance of roller;
2. Waterproof performance of roller;
3. Axial bearing capacity of the roller;
4. The impact resistance of the roller;
5. The service life of the roller.

Classification of rollers:
1. According to the material, it is divided into rubber roller, ceramic roller, nylon roller and insulating roller.
2. There are mainly trough roller groups, various parallel roller groups, various self-aligning roller groups, and various buffer roller groups.
(1) Groove idlers include ordinary idlers, forward inclined idlers, quick-change bearing idlers, hanging idlers, three-chain idlers, reversible idlers, variable groove angle idlers, and transitional idlers. Idler, V-shaped Idler, etc.;
(2) Parallel idlers include ordinary idlers, comb idlers, forward inclined idlers, steel rubber idlers, spiral idlers, etc.;
(3) Self-aligning rollers include universal rollers, friction reversible rollers, powerful rollers, cone rollers, spiral rollers, combined rollers, etc.;
(4) Buffer rollers include spring plate rollers, buffer ring rollers, strong buffer rollers, adjustable elastic rollers, hanging rollers, etc.;
