These pneumatic ATR wheels are 10" in diameter. They come as pair.  The shafts are steel 1/2" diameter shafts with laser cut hubs welded onto them to mate with the wheels bolt pattern.  This shaft and wheel set is intended for our Heavy Duty ATR and Enclosed Heavy Duty ATR.  They kits do NOT include the bearings, since that is part of the Heavy Duty and Enclosed Heavy Duty Kits.  This kit includes 2 shafts, 2 lock collars, 2 wheels, and 8 bolts.  Since these wheels are larger in diamter, the robot will run faster with less torque.  We do not recomend anything faster than our 122 RPM motors, because they will not have enough torqe to turn the wheels in a skid steer.   The 122 RPM motors work great, for added torque the slower gearm motors will work too.  The weight is 7 lbs per pair (2 wheels, 2 axles, and lock collars).

These ARE intended for our:

• Heavy Duty ATR
• Enclosed Heavy Duty ATR

These will NOT work for our:

• Standard IG32 ATR
• Standard IG42 ATR
• IG32 Gearmotor housing
• IG42 Gearmotor housing
• Custom Lenth ATR Side
• Single ATR Motor Mount
