This 8-inch by 3-inch 81 series kingpinless caster, is renowned for it’s unique single ball race design that ensures a high-strength swivel section. These casters are valued for their simplicity and ability to withstand challenging industrial applications with prevalent shock loading. The top plate and yoke base are securely aligned using 3/4 inch high-quality hardened ball bearings, enabling smooth and reliable swiveling. The longevity of these casters is enhanced by their effortless swiveling, result in years of low-cost operation. Manufactured through a drop forged process with C-1045 steel, the yoke and top plate exhibit exceptional strength. The swivel section features a precision-machined 4-inch single ball bearing and a load/thrust raceway in a kingpinless style, where the 3/4 inch diameter load/thrust ball bearings are positioned in shear load, effectively locking the swivel section. Additionally, a mechanical shield safeguards the swivel section from contamination, ensuring reliable performance in demanding environments. 81 Series Kingpinless Casters offer a winning combination of strength, simplicity, and longevity, making them an ideal choice for industrial applications.
Dual Wheel Casters
Dual Wheel Caster configurations are engineered for exceptional load capacity, stability, and versatility in demanding industrial applications. With a dual wheel configuration and low overall height, these casters offer the highest capacity while maintaining space efficiency. Our casters ensure even weight distribution, reducing pressure on flooring and ground surfaces to prevent damage. The innovative design allows for the use of smaller diameter dual wheels, providing optimal load distribution and effortless directional changes.
Combined with Forged Steel wheels, these casters become a powerhouse solution for heavy-duty industrial applications. These wheels are hot forged from high carbon steel billets, enhancing their grain structure, ductility, and tensile strength (64,000 psi). With precision machining, they meet tight tolerances, ensuring flat surfaces with rounded edges. Offering the greatest load capacity, impact strength, and rollability among caster wheels. With the proper wheels and bearings, these wheels are capable of withstanding temperatures up to 800 degrees. Packed with our straight roller bearings, which are most effective for heavy loads, and are a great option when facing excessive thrust loading, these casters are rated for 9000 lbs.
