Model 9 Plate Caster Swivels are the most commonly used industrial caster because of the low initial cost and wide variety of wheels to choose from. The swivel section uses 2 rows of balls on heat treated raceways underneath the mounting plate for reliable rotation. A welded nut and bolt center pin is designed to withstand standard abuse in manually operated applications. Kingpin bolt diameter is 5/8″ and the leg thickness is 1/4″, welded on the inside and out. The axle is 1/2″ in diameter, built to use wheels with a 2 7/16″ hub width. The frames are stamped steel with a zinc plated finish for rust resistance. Lubrication fittings are installed on all moveable parts. A broad selection of wheel brakes and swivel locks is available for most applications. Ideal for aerospace ground support, military maintenance facilities, and government warehousing. Other mounting plate sizes and wheel bearing types are available on request. This caster is also available in a 304 Stainless Steel version for wet or chemically aggressive environments.

Semi-Pneumatic wheels have an extra thick solid soft rubber tire on an industrial plastic wheel center. The absence of air in the tire eliminates the risk of a flat tire. Although less resilient than full pneumatics, semi-pneumatic wheels help reduce vibration and shock caused by floor surfaces which are not smooth. Should not be used on sand or gravel but can be used on grass and other surfaces. Capacity is greater than full pneumatic wheels. All black soft rubber tires contain carbon black and can make marks on floors if dragged instead of allowed to roll. Ideal for applications requiring vibration reduction without pneumatic maintenance.
