Conveyor Roller Load Capacity Guide
Selecting the correct conveyor roller is essential for reliable material handling. The load capacity of a roller depends on several factors including roller diameter, shaft size, bearing type, roller spacing, and load distribution.
This guide provides a general conveyor roller load capacity chart used by engineers while designing roller conveyors.
Factors Affecting Conveyor Roller Load Capacity
1. Roller Diameter
Larger diameter rollers have greater strength and can support higher loads without excessive deflection.
Typical roller sizes used in industrial conveyors:
2. Roller Thickness
The Roller thickness plays important roller in load carrying capacity.
3. Shaft Diameters
The shaft carries most of the load transmitted through the bearings.

Understanding Load Capacity in Conveyor Rollers
Our conveyor rollers are designed to efficiently handle various loads, and it's crucial for designers and users of gravity conveyors to grasp the nuances of load capacity. The information provided below, based on roller lengths in mm and diameters, offers insights into load-bearing capabilities. However, it's essential to note that these figures serve as references and indicators, subject to variations based on component materials and working conditions.
Distribution, Not Concentric:
It's imperative to recognize that the load-carrying capacity of our conveyor rollers is distributive, not concentric. In other words, the capacity is not solely determined by a point load. Instead, it considers the distribution of the load along the length of the roller.
Inverse Relationship with Length:
The load-carrying capacity demonstrates an inverse relationship with the length of the conveyor rollers. As roller length increases, the capacity decreases. This understanding is pivotal for optimal conveyor design, ensuring that the system is tailored to handle loads efficiently.
Consideration for High-Width Products:
For products with greater width, it's important to note that a proportional increase in conveyor roller diameter may be necessary to maintain the desired load capacity. This ensures that the conveyor system can effectively handle the demands of high-width items.
Please be aware that the load capacities provided are for reference and indicative purposes only. The actual capacity may vary based on factors such as component materials and specific working conditions

How to Use This Conveyor Roller Load Capacity Chart
To determine the correct roller for your conveyor:
-
Identify the roller length required for your conveyor width
-
Estimate the load per roller based on the product weight
-
Select the roller diameter that supports the required load
e.g. for a Length of 300mm roller of Dia 60.3 x 1.6mm thick - Load Capacity Comes to 180Kgs
Load capacity depends lot of factors such material in contact with rollers, Working conditions, environmental conditions. etc.
e.g. If there is metal in contact with rollers, higher thickness rollers are suggested, to avoid metal to metal friction.
Roller Pitch and Load Distribution
In most roller conveyors, the load is shared between multiple rollers.
A common design rule:
At least 3 rollers should support the load at any time.
Example:
If a pallet weighs 900 kg:
Supported by 3 rollers
Load per roller ≈ 300 kg
This helps determine the correct roller diameter and shaft size.
Example Roller Selection
Application: Pallet conveyor for 1 ton load
-
Typical configuration:
-
Roller diameter: 89 mm
-
Shaft diameter: 20 mm
-
Roller pitch: 100–120 mm
-
Load per roller: 300–350 kg
-
This configuration is commonly used in warehouse pallet conveyor systems.
Common Conveyor Roller Materials
Rollers are typically manufactured from:
-
Mild steel (MS)
-
Stainless steel (SS304 / SS316)
-
PVC coated rollers
Material selection depends on environment, corrosion resistance, and load conditions.
