Belt Conveyor Roller Idler

Conveyor Belt Rollers Manufacturer,factory In China

Idler rollers for bulk material handling conveyors represent a significant investment in the overall design of the material handling system.

It’s no secret that high-quality idlers are critical to ensuring an efficient, continuous service life for modern conveyors.

GCS idlers for belt conveyors are manufactured according to the highest national and international quality and safety standards: ISO, UNI, DIN, AFNOR, FEM, BS, JIS, SANS and CEMA. Our company pays special attention to every stage of manufacturing, from initial research and engineering to production and rigorous laboratory testing of its performance through specially designed mechanical inspections.

In addition, practical experience accumulated over the years in different factory environments helps provide the best solution for each customer. All mechanical components of the conveyor system must be selected according to technical criteria to ensure plant efficiency and operational cost-effectiveness. Our product catalog includes different ranges and configurations of idlers for belt conveyors, covering a variety of industrial applications for bulk material handling.

These applications vary in the type of material transported, load capacity, particle or lump size, and environmental conditions such as low or high temperatures, salty air, water, and humidity. In addition to standard steel rollers, our company also offers impact and return rollers with rubber rings (including self-cleaning versions), which are required for most bulk handling conveyor systems.

Due to their precise engineering design, GCS belt conveyor rollers can guarantee free, easy, long-term rotation under medium to high loads. In addition to the use of carefully selected materials, an efficient self-lubricating sealing system that protects the roller bearings minimizes the need for regular maintenance. That's why GCS equipment can adapt to a variety of environmental challenges, including dust, dirt, water, low and high temperatures.

GCS idler rollers for belt conveyors are the ideal choice due to their adherence to the following design principles:

By considering these factors and selecting GCS idler rollers designed to meet these requirements, you can ensure smooth and reliable operation while minimizing maintenance demands and enhancing the overall performance of your conveyor system.

Balanced Rotation:

The careful engineering of GCS idler rollers results in balanced rotation, ensuring smooth and consistent operation.

Increased Bearing Life:

The design aims to enhance the lifespan of the bearings, thereby reducing maintenance requirements and downtime for replacement.

Minimal Shell Wear:

The outer shell of the idler rollers is constructed to minimize wear, contributing to longer service life and reduced maintenance costs.

Reduced Inertial Power Consumption:

GCS idler rollers are designed to minimize inertial power consumption, leading to energy efficiency and cost savings.

Noise Reduction:

The rollers are engineered to operate quietly, contributing to a more pleasant and productive working environment.When selecting GCS idler rollers for belt conveyors, it's crucial to consider the following eight key factors to ensure optimal performance and prevent system failures:Material Characteristics: Consider the size, shape, weight, and surface of the materials being conveyed to ensure that the selected idler rollers can effectively handle the specific material properties.

Operating Environment:

Evaluate factors such as impact, work cycles, and spacing to choose idler rollers that can withstand the environmental conditions they will operate in.Roller Dimensions and Belt Width: When selecting the appropriate roller length and diameter, consider the belt width, roller type, and operating speed to ensure compatibility and efficient operation.

Shaft Diameter:

Ensure that the shaft diameter is sufficiently large to support the load and reduce deflection, contributing to stable and reliable operation.

Vibration-Free Operation:

Select idler rollers that enable vibration-free operation to minimize wear and maintenance requirements while ensuring consistent performance.

Sealing Mechanism:

Choose idler rollers with effective sealing mechanisms to prevent the ingress of dirt, water, and other contaminants into the bearings, enhancing reliability and lifespan.

Labyrinth Seals:

Prioritize idler rollers designed and manufactured with labyrinth seal systems to enhance protection and durability in challenging operating environments.

Pre-Lubricated Precision Ball Bearings:

Opt for idler rollers equipped with pre-lubricated precision ball bearings to minimize maintenance needs and maximize operational efficiency.

1.Seal assembly

The seal assembly of idler is made of nylon, and the structural form isnon-contact labyrinth seal structure.

The inner and outer seals form a labyrinth passage with high precision,and the passage is filled with long-acting lithium-based grease, so thatthe idler has good waterproof and dustproof performance.


The bearing of idler adopts special C3 clearance grade deep grooveball bearing.

Before assembly, the bearing of idler has been filled with lithium basegrease and sealed permanently on both sides, which can realizelifetime maintenance free and extend the service life of the bearing.


The shaft of idler adopts high preci-sion cold drawn round steel afterquenching and tempering treatment.Advanced Chamfer milling machineis used to perform accurate machin-ing at both ends of the shaft, so as toensure that the axial displacement ofthe idler is almost zero.

4.Bearing housing

The fabrication of the bearing housing consists of amulti-stageprecision automatic pressing operation, which ensure highaccuracy of bearing and sealing position.

The idler pipes and bearing housing at both ends are 3mmfully fillet welded at the same time through CO, gas shielddouble gun automatic welding machine, which gives aminimumof 70% weld penetration, and ensures that the idler even underthe high load and high speed operation, still strong and durable.


The shell of idler adopts special ratio-fre-quency welded pipe with small bendingdegree and small ellipticity.

The advanced steel tube chamfer cuttingofftool mahine is used for precsemachin-ing of both ends of the pipe, which caneffectively guarantee the concentricityof idlers and minimize the rotation resis-tance of idlers.
