Product Overview

This is the strong polycarbonate plastic hub for the 8 inch Pneumatic Wheel. This product is shipped in kit form. The hub's design is intended to accept any 200x50mm tire and inner tube, 1.125 inch (outside diameter) ball bearings (2 per wheel are needed), and the mounting holes needed to install hardware to be sprocket-driven or hub-driven.

Hardware:
Included Hardware:
  • Two (2) black plastic hub halves
  • Six (6) #4-40x1 Pan Head Phillips thread rolling screws
NOT Included Hardware:
  • bearings
  • #10 screws and nuts needed to mount a hub (2 inch long screws are needed) or a sprocket (2.25 inch long screws are needed)
  • tire and inner tube: Any 200x50mm tire and inner tube can fit this hub, as long as the inner tube has a 90 degree valve stem.
Wheel Structure:
The hub halves are held together with the #4-40 screws. This wheel can accept #10-32 screws for mounting sprockets or hubs, but these are NOT included since different length screws are needed to mount hubs or sprockets. These #10 screws can be mounted to the included 1.875 inch diameter bolt circle. The hub halves need to be assembled together so that the valve stem clearance holes line up. Locating features are present for easy alignment.

Usage:
With Axle and Hub:
  • In order to drive this wheel with a hub, use Hardware Kit 11, which includes #10-32x2 screws (6) and #10-32 nylock nuts (6)
With Sprocket:
  • In order to drive this wheel with a plate sprocket, use Hardware Kit 12, which includes a 550 sprocket spacer, #10-32x2.5 screws (6) and #10-32 nylock nuts (6).
  • Two (2) bearings are needed for this wheel, if being driven by a sprocket. Use bearings with a 1.125 inch outer diameter. No flange is needed on either of the bearings.
Use as a caster:
  • If you want to let this wheel spin without being driven, you will need to install two (2) bearings with 1.125 inch outer diameter.

Specifications

  • Bolt Pattern: 6 holes, 0.20 diameter on 1.875 in. diameter bolt circle
  • Bore: 1.00 in. thru hole, with 1.125 in. x 0.375 in. deep bearing pockets

    Wheels work great!

    We got these wheels to use with some 8x2 wheels we got off of Amazon and they work great! Easy to assemble and look to be nice and strong. It would be nice if the spot where the hubs attach were recessed in to reduce the overall mounting thickness (so we didn't lose dimension for our frame perimeter), maybe for the next casting?

    The whole fits together well.

    These were easy to assemble and use. We were able to swap in various AndyMark wheels because of the standardization.
