3 Inch Swivel Casters TPE Wheels 75mm Heavy Duty Industrial Trolley Wheels

Features and Functional Purpose

This caster is engineered for light to medium-duty industrial applications, prioritizing safety, floor protection, and smooth maneuverability.

• Wheel Material (TPE): The wheel is made from high-quality Thermoplastic Elastomer (TPE) with a hardness of around 85 Shore A . It is designed to be non-marking to protect floor surfaces and often contains trace amounts of oil for enhanced material properties, though this may stain highly absorbent surfaces .

• Maneuverability (Bearing): It features a single ball bearing in the swivel head. This design ensures smooth rolling characteristics, reduces friction, and allows for 360° swivel capability, making equipment easy to steer in tight spaces .

• Safety & Control (Double Brake): The inclusion of a double brake system (often referred to as "stop-fix" or total lock) allows the user to securely lock the wheel in place, preventing accidental movement or rolling on slopes .

• Construction: The wheel center is typically made of high-quality, impact-resistant polypropylene . The bracket is usually constructed from pressed steel with anti-corrosion coatings like zinc plating .

• Compliance: Some models in this category feature ESD (Electrostatic Discharge) protection, safely dissipating static electricity for use in sensitive environments .

Summary of Functional Benefits

Using this caster provides key operational and safety advantages:

• Floor Protection & Quiet Operation: The non-marking TPE wheel is ideal for indoor use as it will not leave scuff marks on tiles, hardwood, or sealed concrete and operates quietly .

• Enhanced Safety: The double brake mechanism allows for instant immobilization of equipment, which is crucial for preventing accidents during loading/unloading or on inclined surfaces .

• Smooth & Reliable Mobility: The single ball bearing swivel ensures effortless directional changes and smooth rolling, reducing the effort required to move equipment .

• Versatile & Durable: It offers high chemical resistance to many aggressive substances and operates effectively in a wide temperature range (typically -20°C to +60°C) .

Ideal Applications

These casters are versatile and suitable for a variety of settings requiring controlled mobility:

• Industrial & Commercial:

  • Industrial carts and light-duty machinery .
