Anyone know the size( diameter, etc) of axle bearing

Are you asking for the wheel hub bearing or the pulley hub side? Wheel hub bearing has the speed sensor in it and can only be purchased through Polaris. The pulley hub side is two pieces and I have not heard of any direct replacement because of the odd bore size. I have the wheel hub bearing dimensions somewhere, just need to find it again, same size of Mazda front wheel hub bearing.

Wheel hub bearing size; 42mm(bore) x 80mm(OD) x 45mm(width) Sealed Angular Ball Bearing
