Description:

Sold as a pair, these 6" ATR wheels are solid core foam rubber and replace the 6" pneumatic wheels. This item also includes a custom machined shaft with a welded hub that matches the bolt pattern of the wheel. The shaft is 1/2" in diameter and has a 8mm bore to accept a motor D shaft. A lock collar is provided to set screw the shaft to the motor shaft. A sealed ball bearing is provided to support the shaft. The ball bearing mounts into our 2nd generation 42mm ATR frames as well as our custom length ATR sides and our single motor mounts.

These wheels work great with our gear motors. The 6mm bore shafts work with the IG32 and IG32P motors. The smaller IG32 motors will struggle a little, our IG32P medium speed motors work great. With a 8mm bore our IG42 gear motors largest gear motors they will climb virtually anything. To calculate the speed of the robot just take the output RPM * wheel diameter (in inches) * 3.14 / 12 = feet per minute.

Features and Specifications:

The shaft is bored with a 8mm hole for mounting onto the IG42 gear motors.
