More Information About This Product

About This Caster - AS40H1TPR

Fit this 4-inch A-Line swivel to an equipment frame that takes one bolt, the hollow-kingpin TPR caster that mounts through its center with a single 1/2-inch bolt and rolls free at the everyday workhorse height.

The hollow kingpin lets a 1/2-inch bolt pass through the center to hold the caster, so a rolling equipment frame mounts with one drilled hole and swaps out fast, and the 4-inch diameter clears most shop sills without raising the frame. The precision ball bearing turns smooth, and the Pemco TPR rubber on a polypropylene core stays soft and quiet with no marks on a finished floor.

Ideal applications

  • Equipment frames that mount on a single bolt
  • Fleets that swap worn casters fast in the field
  • Workhorse-height frames that clear most shop sills

Skip the TPR wheel if the frame loads hard or works near heat over 180°F; a TPU polyurethane or cast iron E-line caster holds up where soft rubber gives.

Pairs with: the AS40H1TPRSB side brake on the corners that stop.

Wrong fit? Want a brake, or a plate mount? See the AS40H1TPRTL total lock and the AS40P1TPR plate swivel.
