Factory cart set of 2 swivel and 2 rigid casters- swivel casters allow cart to turn easily, while rigid casters follow their lead and keep it stable. Very high quality and extra heavy duty- swivel casters have a double raceway of bearings (2 concentric rings) to easily handle both vertical and horizontal stress, while forks are 1/8" extra thick steel. I would guess these to have a 500 lb load rating per caster. Grease fittings on axles and raceways.
4 1/2” overall height. 3 3/4” x 4 5/8” mounting plates. Cleaned with power wire brushes, hand washed and moving parts lubricated.
