Safety recommendations
• Always turn off the power of the drive machine before you
start working.
• Always read and follow the operating instructions.
• Although the laser diode in the laser unit has an output power of
less than 1 mW, never stare directly into the laser transmitter.
• Never aim the laser beam into another person’s eyes.
• Opening the housing of the laser unit may result in hazardous light
exposure and voids the warranty.
• Take care not to pinch your fingers when mounting the units on
the pulley.
• The equipment should not be used in areas where there is a
risk of explosion.
• Never expose the equipment to high humidity or direct contact
with water.
• Have all repair work performed by an SKF repair shop.

1. Introduction
Precise alignment of belt driven machinery is essential to increase belt and
pulley life, reduce vibration, and reduce energy costs.
The SKF TKBA 40 Belt Alignment Tool offers an easy and accurate method to
adjust the machinery so that the grooves of the V-belt pulleys are accurately
aligned.
1.1 Principle of operation
The TKBA 40 consists of two units that attach magnetically to the grooves
of each pulley. One unit, the laser unit, emits a laser line that is projected
onto the receiver unit. The receiver unit has three target areas with three
reference lines, the top reference line and the two bottom reference lines.
Depending on the laser pattern projected on the target area, it is possible to
determine the type of misalignment and how to correct it. Belt alignment is
easily performed by adjusting the moveable machine(s) until the laser line
coincides with the three reference lines on the receiver unit.
