Castor very efficient for sustained use! The orange polyurethane that makes up the wheel is a polymer highly resistant to wear, to which we have added two 638ZZ ball bearings. The inner bore of the bearing is 8 mm with two reduction rings to 6 mm. The fork is made of 2 mm cold-rolled sheets to increase strength. A double ball crown is present to ensure perfect rotation.
The low height of this model allows it to be installed on many workstations without raising the height of workbenches too much, thus reducing musculoskeletal disorders. The positive aspect of this material is that it does not damage floors at all, and rolling is done in complete silence.
