6" Performance Wheel with 1/2" key bore. The Performance wheel is an aluminum version of the 6" plaction wheel with a few changes.   Mounting holes for hubs or sprockets are found on the back side of this wheel.

Specifications:

• Material: 6061 Aluminum
• Weight: 1 lbs.
• Diameter: 6 inches
• Tread Width: 1 inch
• Bore: 1/2" key
  
• Tread Mounting Holes: 6 threaded holes for #10-32 screw on a 1.875" dia bolt circle. Users can drive this wheel with a 1/2" hex shaft. 7 pairs of 0.13" diameter holes (for 1/8 rivets) placed around the perimeter are for attaching tread to wheel by means of rivets

Usage:
There are two ways to drive this wheel. One way is with a Axle and Hub, and the other is with a Sprocket. To attach a sprocket on the side of a Performance wheel use #10-32 x 5/8" screws (3 or 6)

With Axle and Hub:

• If you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the AndyMark hubs (except the Small DD Globe Hub) to this wheel. Hubs are NOT included in the price of the wheel. If this is your choice, then no bearing is needed. To install a hub onto a 6" Performance Wheel, use Hardware Kit 3.

With Sprocket:

• If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and one ball bearing needs to be pressed into the wheel (on one side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0030. For a 3/8" id, use am-0573. Use Hardware Kit 3, which includes the screws for this.
