Polyurethane drive wheels on steel hubs with a keyway, for AGVs, tuggers and powered carts. The key locks the wheel to the motor or gearbox shaft so it cannot slip under torque. Polyurethane grips concrete and coated floors without marking and carries more than rubber of the same size.

Why polyurethane on steel

A drive wheel has to put torque into the floor as well as carry weight. Polyurethane gives grip and holds its shape under load; the steel hub carries the keyway without cracking. Rubber grips better on wet floors but deflects more and wears faster under torque.

Matching the shaft

  1. Measure the shaft diameter. Listed bores include 1/2, 5/8, 3/4, 1, 1-1/4 and 1-1/2 in.
  2. Measure the key width and depth on the shaft.
  3. Check hub length so the wheel seats fully on the shaft.

The listings note that keyways can be machined in most wheel sizes, as long as the hub is large enough [S1].
