Overview

This 54 series heavy duty swivel caster is built for severe service. The hot forged, machined raceway provides a rugged swivel section for abusive applications in the medium heavy duty range. The legs are laser cut of high quality sheet steel and formed on a CNC press brake to provide added strength when side loading or shock loading become an issue. The legs are then welded to the yoke base, both inside and outside, utilizing pulse welding technology to assure great penetration while providing added stability.

The 54 series vertical mounted spring caster excels in reducing noise and protecting cargo from unexpected shocks. Vertical mounted spring casters are ideal for pre-loading, because they are designed to not deflect until the pre-loaded capacity is exceeded. The vertically mounted springs are retained on a rod with threaded ends. The benefit of this design is that there will be no deflection of the springs when loaded with the rated load capacity.
