The medium duty line of 34 Series casters are designed and engineered for loads in the 425-500 lbs. range. The medium duty line provides the user a rugged caster at a lower price point. Carrying capacities vary depending on the wheel tread material.

The 34 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.


Common options include a variety of brakes including cam brakes and tread-lock brakes. Swivel locks can be either factory installed or field installed. Toe guards may also be included.
