Just Cuz Robotics JCR-4935 Motor Magnet Ring Replacement – Repair Made Easy
When building or repairing a combat robot, damage to your weapon motor’s magnet ring is almost inevitable. Traditionally, builders spent time reinforcing their motors by epoxying the magnets for protection. But with the Just Cuz Robotics JCR-4935 Motor Magnet Ring Replacement, you can now replace a damaged ring effortlessly!
As combat robots take hit after hit, magnets can wear out or break. Replacing them used to be tedious, but now it’s as simple as swapping out the ring. The days of manually epoxying magnets are gone. For this motor, the magnets come pre-epoxied, saving you time and effort!
Inspired by the repair tips shared by battle-hardened builders like MadOverlord and Robert Cowan, this ring offers a faster fix—perfect for mid-event repairs or post-battle maintenance.
No more messy epoxy or tedious fixes. Just swap out the damaged ring and get back in the fight. Plus, direct mounting allows for elimination of belts to worry about.
