Belt alignment tool TKBA 40

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.

  • Features and Benefits

    • Powerful magnets allow fast and easy attachment
    • Three-dimensional target area simplifies the alignment process
    • Facilitates simultaneous adjustment of tension and alignment
    • V-guides facilitate the alignment of a wide range of V-belt pulleys
    • Aligns grooves of a V-belt pulley rather than its face, allowing optimum alignment of pulleys of unequal width or with dissimilar faces
    • A maximum operating distance of 6 m (20 ft) accommodates many applications
    • Special side adaptor allowing alignment of multi-ribbed and timing belt pulleys as well as sprockets is available as accessory
