Belt–driven machinery downtime caused
by misalignment is a thing of the past

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
that can result in unplanned machinery downtime. Another side effect
of increased vibration is premature bearing failure. This too can cause
unplanned machinery downtime.
Traditional belt alignment methods
These methods are usually visual in combination with a straight edge
and/or length of string. Although quick to perform, they are often
inaccurate.
Laser belt alignment methods
Using a laser belt alignment tool is quicker and more accurate than
traditional methods. Belt alignment tools can either align the pulley
faces or the pulley grooves.
Accurate pulley and belt alignment can help you:
• Increase bearing life.
• Increase machinery uptime, efficiency and productivity.
• Reduce wear on pulleys and belts.
• Reduce friction and thereby energy consumption.
• Reduce noise and vibration.
• Reduce costs of replacing components and machinery downtime.

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.
• 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.
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.
• Powerful magnets allow fast and easy attachment.
• Facilitates simultaneous adjustment of tension and alignment.
• Can be used on almost all machines using V belts, banded belts,
ribbed belts and most other belts as well as chain sprockets.
• 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.
• Sturdy aluminium housings help ensure assembly stability and
accuracy during the alignment process.
SKF offers a range of three different belt alignment tools to enable accurate alignment
for almost all applications. The tools are designed to be easy to use without any special
training. The laser position indicates the nature of misalignment allowing easy and
accurate adjustment.
