SKF Belt Alignment Tool TKBA 40 (previously TMEB 2)

Highly accurate tool for V-belt pulley alignment

The SKF TKBA 40 aligns V-belt pulleys in the grooves. V–guides and powerful magnets allow the TKBA 40 to be fitted in the grooves of the pulley. With only two components, a laser–emitting unit and a receiver unit, the belt alignment tool is easy and fast to attach. The three–dimensional target area on the receiver unit allows the easy detection of misalignment as well as its nature; whether it is horizontal, vertical, parallel or a combination of all three.
