Looking for industry-standard Thermo Plastic Rubber (TPR) Wheels? CasterHQ offers 4-inch TPR wheels designed for versatile use across various sectors like hospitals, food service, and laboratories. Our gray, non-marking TPR wheels are chemically bonded to a durable Polyolefin core, ensuring maximum quality and longevity.
Unlike standard polyurethane wheels, our Thermo Plastic Rubber wheels come with a softer 75 Shore A Durometer, allowing them to easily roll over obstacles and uneven surfaces. They offer excellent shock absorption, reducing vibrations and ensuring the safety of your valuable cargo.
Please note that while our TPR wheels provide great cushioning, they are not designed to bear heavy loads in a stationary position for extended periods. Prolonged stationary use may result in flat spots that can affect rollability.
Whether you're in need of wheels for computer racks, medical equipment, or food service carts, our 4" Thermo Plastic Rubber wheels are your go-to choice.
For any queries or specialized requirements, call us at 844-439-4335 or Email us here.
