Conveyor Steel Return Carrier Roller Idler Roller For Mining
A side which is used to convey object in a belt conveyor is called carrier side. In side view of main body of a conveyor, a conveyor shapes an oval shape which is long in horizontally and pulleys (rollers) are attached at its both ends. Upper side which is used to carry objects is called carrier side. Rollers that hold conveyor belt at the carrier side is called carrier rollers.
When large conveyance capacity and strength are required for black
rubber belt conveyor, we normally don’t use ready-made conveyor
belt but build-to-order belts. For conveyance of large amounts of
objects, conveyor belt is made to be ship bottom shape (＼＿／), but
not flat. The ship bottom shape is made at conveying side, in other
words carrier side.
In the first place, there are mainly two kinds of rollers. Rollers
holding conveyor belt at transporting side are called carrier
roller and roller holding belt at returning side are called return
rollers.

Conveyor Carrier Roller Features:
1. Manufactured by steel pipe especially for high precision roller, compared with ordinary steel pipe, the diameter and wall thickness tolerance,bending degree,ovality is very little which can make the roller have minimum radial play eccentricity,strong load,low shaking and less noise
2. High precision and brightness cold drawn shaft with 1045 material
3. Rollers are fitted with deep groove 2RS and 2Z bearing with C3 and C4 internal clearance with HRB,SKF,NSK,TNT,FAG brands.
4. Bearing Housing formed by punching many times which can assure high precision. The wall thickness is 1-2mm thicker than DIN standard which can increase 40% stability and roller’s carrying capacity. It can make the roller not deformed even working under overload environment and increase roller’s lifetime.
5. TK contact multiple labyrinth seals made of nylon,ABS have great advantage in water and dust resistance
