Product Description

This 21-inch by 6.90/9-inch 91 Series Extra Heavy Duty Kingpinless caster, is a highly acclaimed industrial solution that excels in rugged applications while minimizing maintenance costs. This caster is valued for its simplicity and ability to withstand industrial environments with prevalent shock loading. The top plate and yoke base are aligned using high-quality 3/4 inch hardened ball bearings, providing stability and reliability. The ingenious swivel section construction places the ball bearings in a sheer load position, ensuring exceptional strength and smooth operation even under heavy loads. With effortless swiveling capabilities, the 91 Series offers extended lifecycles and years of cost-effective operation. Constructed from hot forged C-1045 steel, this caster features a single ball race design with 7/8 inch diameter load/thrust ball bearings in a precision-machined 7-inch diameter raceway. This caster delivers durability, strength, and efficiency, making it the ideal choice for demanding industrial applications.

With wheels that mimick car tires, Pneumatic Casters feature rubber wheels around a metal hub, providing exceptional performance. They excel in moving fragile loads with minimal jarring on various surfaces including grass, pavement, and industrial floors. With quiet operation and load cushioning, they offer protection to both loads and floors. Constructed with hot forged steel and double row ball bearing swivels, these casters ensure durability and a long service life. The pneumatic tires cushion the load, absorb shocks, and effortlessly roll over obstructions. 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 2420 lbs.
