In modern industrial and logistics systems, casters serve as crucial components of mobile equipment, and their performance directly impacts the efficiency and safety of overall operations. Particularly under extreme temperature conditions, the design and material selection for casters must meet even higher standards. This article will take Global Casters as an example to explore in depth the design criteria and practical applications of its double-bearing casters in environments with extreme temperatures.

The core advantages of dual-bearing casters

Dual-bearing casters—designed with two bearings in their structure—offer the following significant advantages over single-bearing designs:

1. Enhanced load-bearing capacity

The double-bearing structure effectively distributes the load, reducing wear pressure on individual bearings and thereby enhancing overall load-bearing performance.

2. Flexible rotational performance

The dual-bearing design significantly reduces rotational resistance, enabling the casters to operate more smoothly during frequent turns or on complex paths.

3. Enhanced durability

The rational distribution of load and stress extends the service life of casters, reducing maintenance frequency and replacement costs.

Challenges posed by extreme temperatures

In extremely hot or extremely cold environments, caster performance is easily affected by the following factors:

1. Changes in Material Properties

High temperatures can cause materials to soften and deform, while low temperatures may make them brittle and prone to cracking, compromising structural stability.

2. Lubrication System Failure

Temperature fluctuations can alter the viscosity of lubricants, leading to insufficient or excessive lubrication and affecting bearing performance efficiency.

3. The Effect of Thermal Expansion and Contraction

Materials expand or contract due to temperature changes, which may lead to variations in the clearance between components, affecting operational accuracy and stability.

Global Caster's Response Standards

To address the challenges posed by extreme temperatures, Global Casters strictly adheres to the following standards throughout the product design and manufacturing process:

1. Preferred Materials

- High-Temperature Environment: Utilizing high-temperature-resistant materials such as stainless steel and superalloys to ensure thermal stability and structural integrity.

- Low-temperature environment: Use low-temperature alloy steels and other materials with excellent cryogenic toughness to enhance impact resistance.

2. Specialized Bearing Design

- High-temperature bearings: Equipped with high-temperature grease and a sealed design to ensure reliable operation under extreme heat conditions.

- Low-temperature bearings: Utilize low-temperature lubricants to prevent freezing, ensuring smooth operation even in extremely cold conditions.

3. Lubrication System Optimization

- High-Temperature Lubrication: Utilizing synthetic lubricants that offer exceptional thermal stability and long-lasting lubrication performance.

- Low-temperature lubrication: Use a low-temperature synthetic oil to maintain excellent fluidity and lubrication performance.

4. Thermal Management Design

- Cooling structure: In high-temperature applications, the casters are designed with heat sinks or ventilation holes to effectively reduce operating temperatures.

- Thermal insulation measures: In low-temperature environments, key components are wrapped with insulating materials to slow down heat loss.
