1. Introduction
1.1 Shaft alignment overview
Shaft misalignment is one of the most significant and most preventable contributors to
premature machine failure. When a machine is placed in service with less than optimal
shaft alignment, the following conditions are likely:
• Poor machine performance
• Increased power consumption
• Increased noise and vibration
• Premature bearing wear
• Accelerated deterioration of gaskets, packing, and mechanical seals
• Higher coupling wear rates
• Increased unplanned downtime
Proper alignment is achieved when the centerlines of each shaft are co-linear when the
machine is under load and at normal operating temperatures. This is often referred to
as shaft-to-shaft alignment. If the shafts of a machine train are not colinear, when the
machine is in operation, they are misaligned.
In essence, the objective is to have a straight line through the centers of all of the shafts of
the machines.
The SKF Shaft Alignment for TKSA 71 is a wireless shaft alignment tool that allows an easy
and accurate method for aligning the shafts of a driving machine (e.g. electric motor) and a
driven machine (e.g. pump).

5SKF TKSA 71 & TKSA 71/PRO
1.2 Principle of operation
The TKSA 71 is a Line Laser Shaft Alignment System and it has two measuring units
that are mounted on each shaft, or on each side of the coupling. After rotating the shafts
into different measuring positions, the system calculates offset and angular misalignment
values between the shafts. The values are compared with user defined tolerance limits and
adjustments of the machine can be made instantly.
During the measuring procedure, measurements are taken in three positions, each
separated by at least 20°. As the shafts are rotated through an arc, any parallel
misalignment or angular misalignment causes the detectors to measure the difference in
their positions relative to each other.
Positioning information from the measuring units is wirelessly communicated through
Bluetooth Low Energy to the displaying device, which calculates the amount of shaft
misalignment and advises corrective adjustments of the machine feet.
If the shafts of a machine train are not co-linear when the machine is in operation, they
are by definition misaligned. While the actual shaft positions can be illustrated in three-
dimensional space and the centerlines can be defined mathematically, it is easier to relate
the relationship between shafts at the coupling as an offset, an angle, or any combination
of the two in the vertical and horizontal axes.

1.4 Pre-alignment
Ensure that all precautions are taken to prevent the machine from accidentally being
started. Lock out / tag out all machines before use.
Check:
• Shim size
• Required tolerances
• Coupling play
• Pipe strain
• Mechanical looseness
• Soft foot

2.2 Handling the measuring units
• Switch on the units by pressing
the power button shortly at the back
of each unit.
• Press the power button until the LED
switches off to turn a unit off.
• The Status LED will turn green when a
unit is switched on.
• The Connection LED will turn blue
when a unit is connected via
Bluetooth to the app.

11SKF TKSA 71 & TKSA 71/PRO
2.3 Charging the measuring units
• Plug the charging pods into a
standard USB charger or a
computer USB port (slower).
• A Red LED shows the charging pod
is connected and operational.
• Place each measuring unit in the center of a charging pod.
The red LED on a Measuring unit indicates:
• ON = Charging correctly
• OFF = Measuring Unit battery is
fully charged
The LED on the charging pod indicates:
• Red = Connected and receiving USB power
• Blue = Connected ready to charge
• Blue Slow Flashing = Charging
• Leave charging until the Red LED on the
measuring unit turns OFF
(about 3 hours for an empty battery).
• Charging the measuring units for
10 minutes will allow for 1 hour usage.

2.4 Setup techniques
Measuring unit M on its shaft bracket.
The chain is hooked from the inside for shafts
with diameter < Ø40 mm (< Ø1.5 inch).
Use the extension chain for shafts
> Ø150 mm (> Ø6.0 inch).
Press both halves of the link connector
together and lock in place by pulling the
chain taut.
Mount the four neodymium magnets and
the shaft bracket can be used as a magnetic
bracket.
Align both fixtures tangentially on the
coupling by using the shaft brackets, or the
magnetic surface of the magnets.

13SKF TKSA 71 & TKSA 71/PRO
2.5 Setup
The measuring unit marked S should be mounted on the stationary machine and the unit
marked M on the movable machine.
Remove the slack of the chains, let the units face each other and tighten them firmly with
the tensioning knobs.
Turn on each measuring unit by pressing the power button and start a new alignment in
the app according to section 3.3 (Main menu). This will activate the laser beams.
Now adjust the position of measuring unit S, on the rods, until its laser line hits the center
of the M target. Tighten the measuring units and brackets in place with the four locking
knobs.
The laser of the M unit can be adjusted with the adjustment knob at the top of the unit,
to the center of the S target.
