What kind of material use for the rollor for 100mm Double Aluminum Omni Wheel w/ Bearing Rollers?

Thanks

Hello @dannyl,

Welcome to RobotShop community.

The rollers are made of rubber.

Let us know if you have further questions.

Sincerely,

I am building a Omnibot to run test for 24/7, but the setscrew on the motor hubs keep loosen or disconnected to the motor shaft after 1/2 day run. I have also changed to use the shaft collar but same thing happen. is there any robust way to secure the motor hubs to the motor shaft ? Thanks

The motor that I am using as below:

Hello @dannyl,

Thank you for your reply.

You have tried the key hub and the set screw hub options and both weren’t enough so we suggest using a hub that has both options together and the set screw is tightened on the shaft itself not on the collar.

Like this one:

Let us know how it goes.

Sincerely,
