3″ Black Polyolefin Bearing Wheel – Stem Model 3

Description

Frames are made from stamped steel and are zinc plated for corrosion resistance.  This institutional stem caster is constructed with two ball bearings on hardened raceways to ensure life of the caster.  Stem Caster Model 3 uses a 3/8” diameter axle and the swivel bearing is held together with a 1/2” rivet.  This stem caster is completed with a metal  dust cover to shield ball bearings in the swivel. Institutional stem casters with stem diameters of this size are not intended to hold more than 1,000 lbs on four of them.

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.
