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.
