Excellent item for small line-following robot
Distance between mounting hole centers was 15mm. Overall height was about 13.6mm. Two 2mm x 12mm pan head Philips screws & nuts were included for mounting along with 2 plastic spacers - 1.62mm & 2.95mm. The ball is very free running and held up well running the robot on concrete floor. Tip: Remove ball from plastic housing before installing screws then pop it back in.
