Choose your selection of 1 or a set of 4 AndyMark 4 inch Mecanum wheels, sold in unassembled kits. All wheels use the same parts, you just assemble them in different configurations to create two left-handed and two right-handed wheels. With a load capacity of 50 pounds per set of four (17 lbs per wheel), these wheels are perfect for a smaller robot like the ones that compete in FIRST Tech Challenge.
If your robot is going to be carrying around more than that, like most FIRST Robotics Competition robots do, check out the 4" HD Mecanum Set, (am-3067).
Here is where you can find replacement rollers.
This wheel is designed to directly mount to any of our Nubs for gearbox attachment.
To use with Axle and Hub:

Returns are accepted within 30 days of purchase.

Do not buy this product for your drivetrain. Buy the BB mecanums for that instead. Or the HD mecanums. Or mecanums from other suppliers I'm begging you. These won't strafe well, are generally fragile and you have to assemble them yourselves. There is a reason why the MecanAM drivetrain does not include these as an option. Are the alternatives more expensive? Yes. But they will actually work as mecanums and you will be able to strafe smoothly. They can be serviceable as low-load FTC-scale intake options. But please, don't put these on your drivetrain.
Very good quality Mecanum wheels.

Easy to assemble. Please send extra spacers and screws on future orders. We lost a piece or 2
Wheels are working great on the robot.

"i love them, but do i need lub the roller? if so which lubs?"
Great wheels -looks cool and kids love it. We weren't able to use them at FTC since it failed the field test :(. (AndyMark Response 9/20/16 : The FTC tile test is to ensure a robot/wheels do not damage the Soft Tile playing surface. This dynamic of the robot is dependent on the wheel, weight of the robot, and gear ratio. We have seen many teams use these wheels with successes over the last few years.)

I had a couple of these get busted up in shipping when I shipped my robot to the west coast. So, I had to buy a couple more sets for spares. Just beware that while they do work, they're not the most robust solution out there.
Andy has an excellent service.
"Nice wheels but we've been having trouble getting our robot to strafe... (AndyMark Response 12/1/14: If you continue to experience difficulties with the wheels please contact us, support@andymark.com, and we would be happy to help you troubleshoot.)"
The wheels are great, but it would have been good for to indicate what size screw was needed to attached the wheel to the hub connector. Would have been better to include them in the kit. (AndyMark Response: The 4 holes near the center of the wheel are clearance holes for a #6 screw, this is the standard screw size used within the Tetrix system. The 6 holes farther out are the AndyMark standard pattern for a #10 screw. Thanks)
I haven't played with the wheels much yet, but service was great!
PROBLEM #1 - One of the wheels did not have the BIG BLACK HUB for the wheel. Not a small screw or a tiny plastic washer, the main part of the wheel. We called immediately to have the part shipped to us. We were told to expect in the next couple of days. PROBLEM #2 A WEEK later it came. PROBLEM #3 It was only part of the hub! PROBLEM #4 It was promised to be over-nighted. STILL NOT HERE. PROBLEM #5 We have a tournament that we have spent thousands of dollars and hundreds of hours preparing for and we only have 3 functioning wheels. PROBLEM #6 The wheels fell a short distance to the ground and cracked one of the rollers. We accept fault for dropping it but I would expect a lot better quality. Strengths: The wheels turn and look nice. Weakness: Poor quality. Look elsewhere. Very little traction on mats. Plastic. Cheap plastic on top of that. Spend your money on quality. (AndyMark Response: We have created white paper (http://files.andymark.com/4inWheelDurabilityWhitePaper.pdf) to discuss these issues and our testing on these wheels.)
