Why RoboRollerz?

The RoboBitz RoboRollerz are a lightweight carbon fiber composite roller system designed specifically for FRC. These rollers are aggressively lighter than comparable products while being less expensive. Lighter, Stronger & Less Expensive? How could you say no?

 

Product Installation:

For competition use, we advise using Loctite 422 (McMaster P/N 74985A67to add additional adherence to the inside of the roller.  Apply it inside the roller tube and insert the roller end making sure to line up the mounting holes.

Apply Loctite 242 (McMaster P/N 91458A112) to the #10-32 mounting screws and torque to 15in/lb.   

For products RB-RR005 and RB-RR006 apply Loctite 242 (McMaster P/N 91458A112) to the end of the 3/8 shoulder bolt and torque to 20in/lb.
