SKF TKBA31 Belt Alignment Tool

Pro advanced tool allowing pulley and chain drive alignment
The tool has two components: a laser-transmitting unit and a receiver unit. Each is attached quickly and easily – using a powerful magnet – to the inside or outside face of a belt pulley or chain sprocket. The TKBA 31 can be applied to most machines that use V belts, banded belts and ribbed belts – as well as those with chain sprockets. A laser line is projected from the transmitter to the receiver – which is mounted on the opposite pulley. The tool then corrects for vertical angle, horizontal angle and parallel misalignment – including combinations of all three. 

Two laser receiver units
Each unit uses a green laser diode and can be used for distances up to 6 m (20 ft) – including outdoors in sunny conditions
Three targets
Three belt tension checkers
Wear check gauges
Fast, easy attachment – using powerful magnets

Applicable to most machines using V belts, banded belts, ribbed belts – as well as chain sprockets
