I'm not exactly an engineer, but my gut is telling me that a second pillow block isn't the answer. I suppose this would depend mostly on where the motor is being held. If you're holding the motor in the front, then there's essentially a pillow block built in. Why would a second one help? Seems like all you'd be doing would be increasing friction (though minimally of course). Although, maybe transfering the side load from a bushing to a bearing would dramatically decrease the friction? If that's the case I worry about my team. We are supporting the end of the drill motor shaft with a ring of self lubricating plastic.

I think the biggest factor is the gear ratio and that's most likely the cause of the problem. What is the gear ratio on your bot?
