Advanced tool allowing belt 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 21 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 transmitter/receiver units
•Uses red laser diodes and can be used for distances up to 3 m (10 ft).
•Fast, easy attachment - using powerful magnets.
•Simplified alignment process
•Simultaneous adjustment of tension and alignment
•Applicable to most machines using V belts, banded belts, ribbed belts - as well as chain sprockets.

Typical applications:
SKF Belt Alignment Tools are commonly used in power plants, recycling facilities, chemical plants, and food & beverage production.

Belt drives are found in a variety of applications, including HVAC, pump installations, paper mills, flour mills, lathe machines, milling machines and conveyors. Sprocket drives are often used in agricultural machinery, compressors, and engine camshafts.

Aligning belt drives and chain drives accurately helps to reduce wear on belts, pulleys, chains, and sprockets. As well as extending belt and pulley life, a precise alignment also reduces machine vibration. Typical benefits of this include improved machine performance, a reduction in unscheduled downtime and lower energy costs.
