At present, the more commonly used aligning idlers mainly include friction aligning idlers, conical aligning idlers, and strong aligning idlers. The center line of the idler and the center line of the conveyor belt is straight, the center line of the idler and the center line of the conveyor belt are not straight, and the 3 grooved rollers and 2 small vertical rollers are installed on the upper crossbeam, and the lower crossbeam is connected to the middle frame. The upper and lower beams are connected together by the reverse axis, and when the conveyor belt is misaligned, the upper beam is driven to rotate around the reverse axis to a certain viewpoint, at this time, the aligning idler applies lateral thrust F to the conveyor belt, which promotes the conveyor belt after misalignment to automatically return to its original position, complete the automatic correction of the misaligned conveyor belt, and ensure the centering operation of the conveyor belt. It is characterized by the addition of 2 gear offset rollers on the basis of forward tilt alignment, which can directly obstruct and restrain the conveyor belt misalignment in the case of serious misalignment, promote the alignment of the conveyor belt, and make the aligning effect better.

GCS Conveyor Supplies is a manufacturer of channel rollers, drums, and frames. Our factory can do it all for bulk material companies, making it simple for everyone to design and order custom rollers and affordable matching roller frames online. The powerful tracking rollers will effectively hold the center of the belt. The center position of the rollers is formed by two synchronized and flexible rotating rollers, and the inclined part is due to longer steel rollers with guide rollers than the center position rollers. It can hold the belt to produce deflection when the conveyor is working. There are carrying tracking rollers and return tracking rollers respectively. The roller frame is also designed to a different standard to be more robust.

Conveyor Roller-The Ultimate Guide

Idlers are cylindrical rods that extend under and along the conveyor belt. It is the most important component/assembly of the trough belt conveyor. The idler is usually located in the trough-shaped metal support frame under the support side to support the conveyor belt and materials.

An important requirement for the idler is the proper support and protection of the belt and the appropriate support for the load being conveyed. Belt conveyor idlers for bulk materials are designed to contain drums of various diameters. The rollers are fitted with antifriction bearings and seals and are mounted on the shaft.

The frictional resistance of the idler roller affects the belt tension and thus the power demand. Roll diameter, bearing design and sealing requirements constitute the main factors affecting frictional resistance.

Choosing the right roll diameter and the size of bearings and shafts is based on the type of service, load carried, belt speed and operating conditions.

Features Of Conveyor Roller

Stable running, good quality with minimum maintenance.

Small vibrating and long lifespan.

Be well dustproof and waterproof.

High accurate steel pipes ensure the rollers/idlers running with low vibration and less noise.

Different Types Of Idler Rollers

There are two types of idler rollers: carrying idlers and return idlers. They are located on the support side and return side of the conveyor. These idlers have many types and functions due to specific applications.

Application Of Conveyor Roller

The products are widely used in coal mines, metallurgy, machinery, ports, construction, electricity, chemistry, food packing and other industries. It endures over 70% resistance of one belt conveyor. The conveyor roller(idler) is used for supporting conveyor belt and the material . There are many kinds roller that we supply, like steel, nylon, ceramic or rubber.
