How to choose the material of the casters?

The material selection of casters needs to be determined based on the actual usage environment and requirements. Here are some common caster materials, their characteristics, and applicable scenarios:

1、 Polyurethane (PU) material

characteristic:

Low noise: Polyurethane casters produce less noise when rolling, making them suitable for environments that require quietness.

High load-bearing capacity: capable of withstanding heavy loads, suitable for heavy-duty equipment.

Strong wear resistance: It has good wear resistance and extends its service life.

Good chemical resistance: Has a certain tolerance to some common industrial chemicals.

Environmentally friendly and odorless: The material is environmentally friendly and does not produce harmful gases.

Applicable scenarios:

Various indoor and outdoor environments, especially those that require quietness, smooth operation, and high ground requirements.

Material handling vehicles, medical equipment, precision instrument transportation equipment, etc. within the factory.

2、 Rubber material

characteristic:

Good elasticity: able to adapt well to uneven ground and ensure the stability of the equipment during movement.

Strong grip: It can better control the direction of equipment movement during starting, stopping, and turning, preventing equipment from sliding.

Wear resistance: Although the wear resistance is generally not as good as polyurethane, it can still meet general usage needs.

Applicable scenarios:

In situations where good grip is required, such as sloping ground or outdoor equipment such as hand carts and electric forklifts.

Handcarts and outdoor mobile equipment on construction sites.

3、 Nylon (PA) material

characteristic:

High strength and rigidity: able to withstand large loads, suitable for the movement of heavy equipment.

Wear resistance: Low friction coefficient on various surfaces, achieving smooth and quiet movement.

Good chemical stability: It can maintain good performance even in environments with chemical erosion.

Applicable scenarios:

On equipment carrying heavier items, such as mobile bases for industrial shelves and mobile devices for heavy machinery.

In heavy industry factories, large machinery and equipment handling vehicles are used.

4、 Steel material

characteristic:

Very high hardness and strength: with strong compressive, bending, and crack resistance, suitable for moving heavy equipment or high load instruments.

Wear resistance: It is not easily damaged after long-term use.

Applicable scenarios:

The movement of heavy industrial equipment with extremely high load-bearing capacity requirements, such as the bottom casters of large mining machinery, heavy forging equipment, etc.

In high load and high wear environments, such as mines, steel casting workshops, etc.

5、 PVC material

characteristic:

Material is hard: low price, light weight.

Wear resistance: suitable for low load handling.

Applicable scenarios:

Low load handling vehicles and mobile racks.

The movement of indoor lightweight equipment, such as furniture, office equipment, etc.

6、 Other materials

MC nylon: It has various unique properties such as light weight, high strength, wear resistance, corrosion resistance, insulation, etc., and is widely used.

TPR (Thermoplastic Rubber): Silent and cost-effective, but slightly weaker in elasticity than natural rubber.

Modified engineering materials: After technological improvements to increase strength, improve wear resistance and stability, the material is relatively hard and cost-effective, suitable for industrial applications such as rushed equipment and turnover vehicles.

7、 Choose Suggestions

Consider load capacity: Choose wheels with appropriate load capacity based on the weight of the equipment and the weight of the items to be transported.

Consider ground conditions: Choose the appropriate caster material and hardness based on the material and flatness of the ground.

Consider moving distance: For devices that require long-term or long-distance movement, choose casters with better wear resistance.

Consider environmental factors such as temperature, humidity, chemical substances, and their impact on the material of the wheels.

In summary, the material selection of casters requires comprehensive consideration of multiple factors, including load capacity, ground conditions, movement distance, and environmental factors. In practical applications, suitable caster materials can be selected based on specific needs and usage scenarios.
