40 SERIES MEDIUM DUTY CASTER
Utilizes a stem (or possibly a rivet or bolt) on the top plate to fasten together the lower swivel section. Along with making use of load bearing and thrust bearings to help transport heavy loads. This allows varying levels of swivel resistance. Designed for efficiency in multiple applications; with advantages such as allowing the user to tighten the kingpin nut as the swivel wears, leading to a prolonged caster life and allowing easier cleaning of the swivel section.
