Stone Crusher 200kg Conveyor Return Roller With 6203 C3 Bearing
Premium Quality Conveyor Iron Disc Flat Return Idler Roller For
Stone Crusher
Iron Disc Return roller is suitable for conveyors in the industry.
Iron Disc Return 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. Iron Disc Return 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.
What are the differences between the buffer roller rubber ring and
the ordinary buffer roller
(1) Long service life. The polymer material used in the roller body
of the idler has mechanical properties similar to bronze, has good
properties, and has good self-lubricating properties, and does not
damage the belt.
(2) Superior anti-corrosion performance. Both the roller body and
the seal are made of polymer materials. Used in corrosive
occasions, the service life can reach more than 5 times that of
ordinary rollers. The specifications of polymer corrosion rollers
include 4 series, including φ89, φ108, φ133, φ159, etc., with more
than 30 varieties. Non-standard rollers can also be manufactured
according to user requirements. There are two types of roller body
materials: mc nylon and polyurethane, which are selected according
to the characteristics of corrosive substances in the use
environment.
(3) Light weight and low rotational inertia. The polymer material
used for the roller is light in weight, and its specific gravity is
one-seventh of that of steel. The weight of the roller made of this
material is about one-half of the weight of the ordinary roller,
and the rotation inertia is small. It is between the roller and the
belt. The friction is small.

Main classification of rollers:
There are several standards for the quality of the Iron Return Disc
Conveyor Roller : the radial runout of the roller; the flexibility
of the roller; the amount of axial movement.
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) Trough idlers include ordinary idlers, forward inclined idlers,
quick-change bearing idlers, hanging idlers, triple 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, powerful buffer rollers, adjustable elastic rollers,
hanging rollers, etc.
