This 4-inch by 2-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 our 1-inch thick tread, T/R 85A polyurethane wheel, this caster is a versatile solution that brings industrial-strength performance with a softer touch. This specialized formulation is engineered for easy and quiet rolling, making it an ideal choice for a wide range of applications. With its high tear and debris resistance, this wheel ensures exceptional durability and longevity. While offering moderate solvent and oil resistance, it is important to note its lack of water resistance and unsuitability for hot and humid environments due to the risk of microbial attack. 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 600 lbs.
