This 10-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.
Paired with a Laminated Phenolic wheel, this combination provides reliable support for heavy loads and minimize the risk of failure. They resist wear, impacts, and abrasion, extending their lifespan and reducing maintenance. These wheels withstand high temperatures, resist chemicals, and deliver a quieter working environment due to their vibration-dampening properties. Overall, laminated phenolic caster wheels combine durability, reliability, and low maintenance for excellent performance in demanding applications. 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 3250 lbs.
