Heavy Duty Conveyor Flat Return Roller Idler for Belt Conveyor
Flat Return Idler automatically prevents the belt from misalignment
and protect the belt edges from damages.
The return idlers is used to carry the the empty belt in the return
side or the lower side of the conveyor belt.
Self-Training Flat Return Idler automatically prevents the belt
from misalignment and protect the belt edges from damages. The
self-training flat return idler is used to adjust the misalignment
on the return side.
flat return roller suspended frames are commonly used on
underground conveyor structure for ease of removal. These are
designed to suit the customers specific loading requirements, and
are available in high quality hot-dip galvanised steel as standard.
Roller-Housing:
Housing is completed through sequential punching on imported
superior steel sheet(SPCC), Finished housing features even
thickness, good surface, precise measurement and consistency. Inner
radius of housing completed is in conformity with designed value
and roughness required by bearing and tube. The surface of housing
is phosphated and degreased to improve cohesion of painting film.
Roller seal arrangement:
selects labyrinth sealing arrangement which consists of two
non-contact seals(inner seal and outer seal)and is waterproof with
low rotation drag. All seals are made from PA/ABS. uses top
lithium-based grease to fill in seals.
Roller-Bearing:
roller bearing uses double seal (ZZ) deep groove ball bearing with
C3 clearance. Volume of lithium based grease filled inside ranges
from 1/2 to 2/3, which secures the long service life.(Note: In view
of visibility, the bearing on right graph omitted).

Main Features
1) Solid design, suitable for heavy lifting.
2) The bearing housing and steel tube are assembled and welded with
a concentric automatic.
3) Cutting of the steel tube and bearing is performed with the use
of a digital auto device/machine/equipment..
4) The bearing end is constructed to ensure that the roller shaft
and bearing can be firmly connected.
5) Fabrication of the roller is effected by an auto device and 100%
tested for its concentricity.
6) Roller and supporting components/materials are manufactured to
DIN/ AFNOR/ FEM/ ASTM/ CEMA standard.
