4 Inch 100mm High Quality TPE Caster Wheel with Single Ball Bearing and Double Brake for Industrial Equipment
These 4-inch Thermoplastic Elastomer casters are durable, non-marking, and quiet wheels that blend the best qualities of hard and soft materials. Ideal for medical, food service, and institutional environments, they offer excellent shock absorption, floor protection, and chemical resistance. They are often used on carts, furniture, and delicate flooring.
Key Features & Benefits
- High-Performance TPE Material: The tread is made of Thermoplastic Elastomer (TPE), typically with a hardness of 85 Shore A. This material is durable and wear-resistant, but its main advantages are that it operates quietly, is non-marking, and protects floors from scratches, making it ideal for sensitive environments.
- Smooth Operation & Durability: The chassis is usually constructed from zinc-plated, corrosion-resistant steel for long-lasting structural integrity. The integrated single ball bearing in the wheel ensures smooth rolling and easy swiveling, even under load.
- Dual Brake System for Maximum Safety: This is the most critical safety feature. The double brake simultaneously locks both the wheel's rotation and the swivel action of the caster. This completely immobilizes the equipment, preventing any accidental movement. This is essential for precise positioning or when working on slight inclines, significantly enhancing safety.
- Wide Environmental Adaptability: With an operating temperature range typically between -20°C and +60°C, these casters can function in various environments. TPE is also resistant to many corrosive chemicals. Some models may feature ESD (Electrostatic Discharge) protection to safely dissipate static electricity, which is vital for protecting sensitive electronics.
Typical Applications
These features make this caster ideal for:
- Medical Equipment: Such as hospital beds and surgical carts, where quiet operation, easy cleaning, and secure locking are required.
- Food Processing & Catering: They can withstand frequent washing, resist moisture, and will not leave marks on floors.
- Factories & Workshops: Used on tool carts, workbenches, and material racks that need frequent movement and reliable positioning.
- Warehousing & Logistics: Used with light to medium-duty shelving and transport carts to improve efficiency.
