Suitable alternatives?

[joelg236]

I've been asked to order these parts, which are out of stock at the moment:

Vex Pro
Flanged Bearing - 1/2" Hex ID x 1.125" OD
http://www.vexrobotics.com/vexpro/sh.../bearings.html

West Coast Products
Colson Hub: 1.5” Wide Wheel Live Hub
http://wcproducts.net/wcp-00053/

Andy Mark
Timing Belt, Gates HTD, 15mm wide, 160T, 800-5M-15 (am-2266)
http://www.andymark.com/product-p/am-2266.htm

I've found this so far:

Flanged Bearing - 1/2" Hex ID x 1.125" OD
http://www.andymark.com/product-p/am-0279.htm

Colson Hub: 1.5” Wide Wheel Live Hub
http://www.robotmarketplace.com/prod...WCP-00053.html

And nothing so far for belts (we have a KoP set - is this the same thing?)


Sorry if these are easy questions, not my realm of expertise
