This 6-inch by 2-inch T/R 85A Polyurethane Keyway Caster Wheel is designed to combine industrial-strength performance with a softer touch. This specialized formulation is engineered for easy and quiet rolling, making it an ideal choice for various applications that require precise positioning. With its high tear and debris resistance, it ensures exceptional durability and longevity, even in demanding environments. While offering moderate solvent and oil resistance, it is important to note its lack of water resistance and unsuitability for hot and humid areas due to the risk of microbial attack. Additionally, the keyway design of this wheel provides enhanced stability and prevents slippage, ensuring reliable performance and precise maneuverability in industrial settings, while handling loads up to 640 lbs.
