This 4-inch by 1.5-inch 51 series kingpinless caster, is a reliable and cost-effective solution for demanding industrial applications. Renowned for its durability and minimal maintenance requirements, this caster is a valuable investment that reduces downtime and maintenance costs. Designed to withstand abusive environments with prevalent shock loading, it offers a tough and resilient performance. The swivel section of the caster features heat-treated inner and outer rings, securely aligned by high-quality hardened 3/8 inch ball bearings. This construction ensures exceptional strength and smooth operation even under heavy loads. The kingpinless style caster is particularly favored for applications where manual ergonomic operation is crucial, thanks to its effortless swiveling capability. The hardened alloy swivel sections and robust formed and welded legs provide outstanding strength and durability, making the Series 51 caster ideal for challenging industrial environments.
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. Featuring our precision tapered bearings, the wheels are capable of absorbing excessive side thrust loading and can be used where high speed operation is essential, all with a load rating of 1400 lbs.
