127mm Rubber Coated Conveyor Drive Rollers For Conveyor Transport System
Rubber Disc Comb Return Roller for Conveyor Transport System
The Rubber Disc Return Roller accessories have a reasonable structure and a firm seal. The roller accessories are equipped with two seals, which have high production accuracy. The vacancies are coated with grease, which can effectively prevent corrosive media such as dust, gas, and liquid from entering the roller and damaging the roller bearings. The sealing function of the roller accessories promotes its different development and application, its application function and value.
The Rubber Disc Return Roller accessories are damaged and have a long service life. The polymer material of the roller body of the idler has a mechanical function similar to that of bronze. It has the self-lubricating function and does not damage the belt. The machining accuracy of the roller accessories refers to the concentricity of the inner holes at both ends of the shell and the roller, and the standard machining accuracy of each component in the axial direction. If the concentricity is too poor, it will cause the rolling bearing to seize, increase the resistance, and reduce the service life. The manufacturing skills of roller accessories will affect the dynamic load of the roller. The root cause of the movement is the unequal wall thickness of the roller shell and the radial jump of the shell. The role and value of the roller accessories can be reflected in the use of the roller, which can supplement the roller.
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.

The basic types of rollers:
(1) The rollers are classified into self-aligning rollers, buffer rollers, trough rollers, and parallel rollers according to their uses. The function of the self-aligning roller is to correct the deviation of the belt of the belt conveyor. Usually, a rotary groove-shaped self-aligning roller is installed on the heavy-duty section of the conveyor, and a parallel self-aligning roller is installed on the no-load section. The buffer roller is applied to the tailstock of the machine according to the actual situation. When receiving the material, it can reduce the impact of the material on the belt, which is beneficial to the service life of the long belt. The trough-shaped roller is generally composed of two side rollers and a flat roller. The groove angle is generally 30 degrees. For a detachable belt conveyor, the three rollers of the trough-shaped roller are hinged to each other, so Called hinged roller. The parallel roller is generally a long roller, which is installed at the lower end under pressure, so it is called the lower roller.
(2) The rollers are divided into two types: steel rollers and plastic rollers. There are three types of bearing seats for rollers: cast iron, stamped steel plate and phenolic plastic.
