What applications are suitable for different types of nylon casters?

Applications of different nylon caster types
Nylon casters come in a variety of types due to differences in material modification and structural design. They require precise matching based on application requirements. The core types and their application scenarios are as follows:

1. Material Classification: Ordinary Nylon Wheels vs. Reinforced Nylon Wheels
Ordinary nylon wheels (PA6/PA66): They offer moderate hardness and low cost, making them suitable for light loads and smooth surfaces, such as home storage cabinets, office chairs, and light utility carts (load capacity 50-150kg). They are suitable for tiled, wooden floors, and smooth concrete floors. They reduce scratches and offer excellent noise reduction, meeting low-noise requirements for indoor use.

Glass-fiber-reinforced nylon wheels (PA + glass fiber): Offer 30%-50% increased mechanical strength, strong wear resistance, and excellent deformation resistance. They are suitable for medium-to-heavy loads and rough surfaces, such as industrial carts, warehouse shelving, and medium-sized equipment (load capacity 150-500kg). They can be used on concrete floors in workshops and outdoor asphalt roads, and can withstand the wear and tear of frequent rolling, extending their service life.

2. By Structure: Fixed Wheels vs. Universal Wheels vs. Wheels with Brakes

Definitely fixed nylon wheels: Roll only in a fixed direction, offering high stability. Suitable for linear transport applications, such as assembly line conveyors and heavy-duty cargo transfer carts. They prevent deviation during transport and ensure accurate delivery of goods, making them particularly well-suited for workshops and warehouses requiring fixed routes.

Universal nylon wheels: Offer 360° steering and high flexibility. Suitable for applications requiring frequent directional changes, such as supermarket shopping carts, medical equipment carts, and office chairs. They facilitate maneuvering in narrow spaces and enhance ease of operation. Models with double ball bearings are particularly suitable for precision instrument carts, reducing the impact of vibration on equipment. Nylon wheels with brakes:

These wheels feature a brake function and are suitable for temporary fixed applications, such as operating tables, display stands, and outdoor umbrella bases. Locking the brake prevents the wheels from slipping, ensuring safety. The fully enclosed brake structure also prevents debris from getting stuck, making them suitable for a variety of environments, including hospitals, shopping malls, and outdoor spaces.

3. Environmental Resistance: Conventional Heat-Resistant Wheels vs. Low-Temperature/Chemical-Resistant Wheels
Conventional Heat-Resistant Nylon Wheels (-20°C-80°C): Suitable for most normal temperature environments, such as indoor warehouses, office buildings, and homes, and can withstand daily temperature fluctuations.

Low-Temperature-Resistant Nylon Wheels (below -40°C): Contain an antifreeze modifier to resist brittle cracking at low temperatures, making them suitable for cold storage and outdoor applications in northern China, such as cold storage cargo carts and outdoor cleaning equipment.

Chemical-Resistant Nylon Wheels: Acid- and alkali-resistant treatments ensure they withstand corrosion from weak acids, bases, and oils. They are suitable for use in laboratories and chemical workshops, such as chemical reagent transfer carts and oil-stain cleanup carts, to prevent material swelling and damage.
