These wheels are constructed with a thermoplastic rubber tread bonded to a polypropylene core making them light weight and durable while providing excellent traction. They mount on a 1/2" keyed shaft.
These wheels feature an integrated keyed mounting hub allowing them to be mounted directly to a 1/2 keyed shaft no separate hub required.
NOTE: The broached polypropylene core should be durable enough for most applications; however, it may not be suitable for some strenuous applications. It is recommended to use a separate hub solution for strenuous applications.
NOTE: An 1/8 machine key is required to mount these wheels to a 1/2 keyed shaft.
