Conveyor Idler Steel Carrier Roller For Bulk Materials Handling
Belt conveyor idler belt drive is widely used in machinery. Compared with meshing drive (gear, worm gear drive), belt drive has the following characteristics:
(1) The structure is simple, the manufacturing cost is low, and the installation and maintenance are convenient.
(2) The belt is rich in elasticity, which can alleviate shock and vibration, so it runs smoothly and has low noise during operation.
(3) It is suitable for transmission with a large center distance, but on the other hand, the outer size of the transmission is large and the compactness is poor.
(4) The elastic sliding of the belt on the pulley changes with the change of the load, so the transmission ratio is not accurate. However, when overloaded, slippage can occur. Therefore, damage to other transmission parts can be prevented. But it is usually not used as an overload protection device.
(5) The belt must be tensioned, so that the shaft and bearing are subjected to a large force.
(6) The belt and pulley will generate heat and electricity due to friction, so it is not suitable for use in places where there is a danger of explosion.
(7) The efficiency and durability of the belt drive are low. Compared with the flat belt drive, the V-belt has the advantages of larger transmission ratio i, smaller center distance A, more compact transmission outline size, and smaller belt sliding and tension.
Features of trough rollers
1. Flat/Carrier/Carrying Rollers: Used to handle bulk&unit material.
2. Impact Rollers: Installed at the loading point to absorb the shocks and to help protect against belt damage.
3. Return Rollers: Used to sustain and support the belt during its return section and performs a cleaning action
--- Return rollers with Spaced Rings (Rubber Disc Rollers)
--- Return Rollers with Helical Rubber Rings (Spiral Rollers)
4. Self-aligning/Training Rollers: Used to adjust the belt deviation, preventing hunting and ensuring stable operation of conveyor belt.
--- Tapered self-aligning rollers
--- Friction self-aligning rollers

The characteristics of trough rollers are mainly reflected in the following aspects:
A. The trough type roller produced by our company has no effect on acid, alkali and salt, and has strong corrosion resistance;
B. The trough rollers produced by our company have strong hardness and strong wear resistance;
C. The trough rollers produced by our company have very good sealing performance, and oily grease will not leak;
D. An oxide film is formed on the ceramic surface of the trough roller, which has a small friction coefficient in contact with the conveyor belt, which can effectively reduce the driving force of the winding.
E. Long service life of trough roller;
F. Trough rollers can reduce the overall cost of belt conveyors, reduce maintenance man-hours, and lower operating costs.
