Belt alignment tool SKF TKBA 40

High-accuracy tool for V-belt pulley alignment

Belt-driven machinery must be precisely aligned in order to increase belt and pulley life – and reduce both machine vibration and energy costs. SKF’s TKBA 40 Belt alignment tool offers a straightforward way to do this, by accurately aligning the grooves of V-belt pulleys.

It can correct for vertical angle, horizontal angle, and parallel misalignment. The tool has two components – a laser-emitting unit and a receiver unit. It uses powerful magnets and V-guides to fit to the pulley’s grooves, allowing the TKBA 40 to be attached quickly and easily.

Fast, easy attachment – using powerful magnets
Simplified alignment process
Ability to align a wide range of V-belt pulleys, as four sizes of V-guide are supplied
Simultaneous adjustment of tension and alignment
Aligns grooves – rather than faces – of V-belt pulley, for optimum alignment of pulleys of dissimilar widths or faces
Optional extra: a special side adaptor allows alignment of multi-ribbed and timing belt pulleys, as well as sprockets
Maximum operating distance of 6 m (20 ft) accommodates many applications
Relies on red laser diode, and is supplied in a sturdy carrying case
Runs on 2 × AAA batteries for 20 hours of continuous operation

The TKBA 40 can be applied to a number of end-use applications:

Belt drives:

HVAC , Pump installations , Paper mills , Flour mills , Lathe machine , Milling machines , Conveyors

Sprocket drives:

Agricultural machinery , Compressors , Engine camshafts

The TKBA 40 is supplied with four sizes of V-guide – to fit pulley grooves of most widths and types. Exchanging a V-guide for a smaller or larger one is a straightforward operation.

The laser unit emits a laser line that is projected onto the receiver unit. A three-dimensional target area on the receiver unit allows easy detection of the type of misalignment and how to correct it.

Belt alignment is achieved when the laser line coincides with the three reference lines on the receiver unit.

One of the common reasons for unplanned downtime of belt-driven machinery is pulley misalignment. Pulley misalignment can increase wear on pulleys and belts as well as increasing the noise and vibration level. A side effect of increased vibration is premature bearing failure. All this can cause unplanned machinery downtime.
