There is no fixed universal formula for calculating the load capacity of 5 inch yellow PU wheel, and a more economical and practical replacement requires finding the correct direction from the wheel core material and internal bearings.
The core of load capacity is to ensure that the rated load of a 5 inch yellow PU wheel is greater than the maximum weight it needs to bear in actual use. You can estimate according to the following formula:
The required load capacity for a single wheel=(equipment weight+maximum load weight) x safety factor/number of effective casters
1. Detailed explanation of calculation parameters
Equipment self weight+maximum load weight: the total weight of the cart and equipment when fully loaded.
Effective number of casters (n):
Solid goods: usually calculated based on 3 wheels. When the ground is not completely flat, only 3 out of 4 wheels may land simultaneously.
Liquid cargo: usually calculated based on 2 wheels. Liquid shaking can cause the center of gravity to shift, and the instantaneous weight will be more concentrated on a few wheels.
Safety factor: It is recommended to take a value between 1.3 and 1.5, leaving room for the impact force generated by emergency stops, passing through obstacles, or uneven road surfaces
There are many types of materials and structures for 2.5-inch yellow PU wheels, with significant differences in load capacity. You can benchmark based on the wheels in your hand:
1) Standard Type: Approximately 280-380 kg, the most common commercial grade configuration
2) Lightweight/economical: about 200 kg, smaller size, or using plastic wheel cores
3) Heavy/Reinforced Type: Approximately 450 kg, featuring a more robust aluminum core and larger bearings
For example, a cart with a self weight of 50kg can carry a maximum load of 200kg and a total weight of 250kg. Calculated based on 4 wheels and solid cargo, 250kg ÷ 3 × 1.5 (safety factor)=125kg. This means that you need to choose at least a single wheel with a rated load of 125kg or more.
