Polypropylene Rigid Caster - 3" x 1" 176 Lb. Capacity

Polypropylene rigid casters roll smoothly on tile, sealed concrete, epoxy, and other hard, flat surfaces. The non-marking tread protects finished floors in powder coating shops and clean rooms. Avoid rough concrete or outdoor gravel, which increases rolling resistance and accelerates tread wear.

Each caster supports up to 176 pounds. For a four-caster cart, the combined static load capacity is 704 pounds when the weight is evenly distributed. Reduce the working load by 25 percent if the cart will be pushed over door thresholds or expansion joints.

Yes. The polypropylene wheel resists most acids, bases, and solvents used in coating and finishing shops. The zinc-plated yoke and axle hardware resist rust in humid environments. These casters do not require lubrication or anti-corrosion treatments under normal indoor use.

Rigid casters are fixed in one direction and provide straight-line tracking. Swivel casters rotate 360 degrees for maneuverability. Most carts use two rigid casters on the rear and two swivel casters on the front for stable, steerable movement along production lines.

No. The polypropylene tread is non-marking and non-staining. It does not leave black scuff marks on epoxy, tile, or sealed concrete. This makes these casters a good fit for showrooms, clean rooms, and finished coating areas where floor appearance matters.
