Each and every component that goes into creating the right caster for your application can make the difference in performance and durability. Take, for example, a bolt.
Simply put a bolt is the supporting shaft a wheel or a set of wheels revolves on. It places through the bearing then attaches the wheel to the forks of a caster. But not all axles are created the same. Some axles have zerk fittings on them that allow for lubrication of the bearing without removing the wheel from the forks, some do not.
We at Caster Technology strive to make sure that you will have the caster that is right for you, that is why we offer a complete line axles designed for specific handling applications and conditions.
