Belt alignment tools TKBA 10 and TKBA 20

Versatile tools for pulley and sprocket alignment

The SKF TKBA 10 and TKBA 20 allow pulleys and sprockets to be aligned on the side face. The unit magnetically attaches to the inside or outside face of almost any belt pulley or chain sprocket and has no small parts or targets that can get lost. A laser line is projected from the transmitter unit to the reflector unit mounted on the opposite pulley. A reference line on the reflector unit directly indicates the offset and vertical angle misalignment. The reflected laser line shown on the transmitter unit shows the horizontal angle misalignment of all three.

SKF TKBA 10

Utilises a red laser and can be used for distances up to 3 m (10 ft).

SKF TKBA 20

Utilises a highly visible green laser and can be used for distances up to 6 m (20 ft). It can even be used outdoors in sunny conditions.
