Product Overview:
The inside black portion of this wheel is made from molded polycarbonate plastic. The outer tread is TPU (thermoplastic polyurethane) with a 77a durometer hardness. This robust but lightweight wheel provides good traction on carpet and soft tiles. The Stealth wheels are the perfect wheel for intakes and other auxiliary robot mechanisms. The bore of this wheel is a 1/2" hex hole, which is intended to be driven by a 1/2" hex shaft or spinning axle. There is a bolt pattern on a 1.875" diameter bolt circle for mounting sprockets, hubs, and gears.

Product Usage:
Many thread locking materials are not compatible with polycarbonate and can eat away at the plastic. Be sure to check which adhesives are okay to use with this product. This link will allow you to check which materials are okay to use with what adhesives, http://bit.ly/loctitematerialcheck
