Not every production line requires a large conveyor system. For small products or facilities with limited installation space, mini conveyor rollers provide an efficient solution that optimizes space utilization, ensures stable product movement, and integrates easily into automated systems. Based on Belota’s experience in industrial roller design and manufacturing, this article explores the structure, specifications, common types, applications, and key selection criteria for mini conveyor rollers.
What Are Mini Conveyor Rollers?
Mini conveyor rollers are industrial rollers with compact dimensions, typically featuring diameters ranging from 20 mm to 50 mm. The cylindrical roller body rotates around a shaft through a bearing system, reducing friction and enabling smooth product transportation.
These rollers are widely used in gravity roller conveyors and powered roller conveyor systems for handling small to medium-sized products.
Basic Structure of Mini Conveyor Rollers
A complete mini conveyor roller generally consists of the following components:
Roller Tube
The roller tube is the main body of the roller and is commonly manufactured from steel, stainless steel, or engineering plastics. Its diameter and wall thickness directly influence load capacity, durability, and service life.
Roller Shaft
The shaft connects the roller to the conveyor frame and transfers operational loads. Depending on the application, shafts can be manufactured from C45 steel, stainless steel 304, or stainless steel 316.
Bearings
Bearings allow the roller to rotate smoothly while minimizing friction and operating noise. Common bearing models include 608, 6001, and 6002, selected according to load requirements and working conditions.
Protective End Caps
Installed at both ends of the roller, end caps protect the bearings from dust, moisture, and environmental contaminants, extending the service life of the roller assembly.
Surface Coating (Optional)
For specialized applications, rollers may be coated with rubber, polyurethane (PU), or anti-static materials to increase grip, reduce slippage, and protect conveyed products.
Common Technical Specifications
Depending on product dimensions, load requirements, and operating conditions, mini conveyor rollers can be customized accordingly.
| Specification | Typical Value |
|---|---|
| Roller Diameter | 20 – 50 mm |
| Roller Length | 100 – 600 mm |
| Shaft Diameter | 6 – 20 mm |
| Working Load Capacity | 20 – 200 kg/roller |
| Rotational Speed | 50 – 400 RPM |
| Materials | Steel, Stainless Steel 304/316, POM, PP |
Note: These values are for reference only. At Belota, mini conveyor rollers can be custom-manufactured according to specific requirements regarding dimensions, materials, load capacity, and operating environments.
