A traditional caster design, the hot forged top plate and yoke base are held securely in alignment with a grade 5 kingbolt. The kingbolt is tightened to assure smooth swivel action before being pinned in place. The hot forged swivel sections and industrial width wheels are well suited for many in-plant applications. The added strength of the kingbolt provides extended caster service life in very demanding environments.

The 74 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.
