4″ Polyolefin Swivel Wheel – K3A B

Description

4″ Black Donut Polyolefin Wheel. Ball Bearings in the Wheel. Shown with 5″ wheel. This K3A plate caster is our zinc plated total locking institutional caster which uses the same Model 3 1-¼” wide wheels. Plate Caster Model K3A is made using a stamped steel construction and is zinc plated. This plate caster uses a ⅜” diameter axle and the swivel caster raceway is held together by a ½” diameter rivet. This plate caster comes with two rows of ball bearings which makes changing direction and swiveling easier. There is a solid cover over the swivel raceways to shield them from dirt and dust. This plate caster performs best if you limit the load to no more than 1200 lbs on a set of 4 Model K3A casters.

Polyolefin Caster Wheels are injection molded from a blend of thermoplastic polymers forming a one piece solid sanitary design. These Polyolefin wheels are especially suited for wet and corrosive applications. They are very resistant to most commonly encountered liquids. Polyolefin wheels have a lower capacity and a more limited temperature range than Nylon wheels. In a cold dry environment, such as a refrigerated store room, Polyolefin wheels may become brittle. They should not be used in a freezer or a heat application above 180°F intermittent usage, such as a rack washer.

This donut shaped wheel comes with sealed ball bearings in the wheel. It’s tread shape enables it to change directions much more easily.
