These versatile white plastic wheels have silicone tires and measure 80mm (3.15″) in diameter.

What makes them special is the included set of interchangeable collets that can be inserted into the wheel to firmly grab four different shaft types: 3mm D, 3mm round, 4mm D, and 4mm round.

The collet inserts start with a comfortably loose fit on their intended shafts, and unlike simple press-fit wheels, their grip on the shaft gets progressively tighter as they are compressed into the wheel disc, reducing the chances that the shaft will be able to slip within the wheel.

Note: Gear motor pictured is not included with this item.

This product is a pair of white 80×10mm wheels, and it consists of two sets of the following parts:

  • Silicone tire
  • White ABS wheel disc
  • Four white ABS collet inserts:
    • Collet for 3mm D-shafts
    • Collet for 3mm round shafts
    • Collet for 4mm D-shafts
    • Collet for 4mm round shafts
  • Threaded metal collet plate
  • Three 7mm-long M3 screws
