2.0 Overview
Constructed from a combination of hard-wearing stainless steel and lightweight
aluminium, the ABT5210 Ri59, Ri60, Ri60 P10 and 41GPU Grooved Wear Gauges are a
compact solution to measuring side and headwear.
The side and headwear are measured mechanically on a pair of linear stainless steel
scales via a horizontal and vertical slide respectively.
The gauges measures the following parameters:
•Sidewear
•Headwear

4.0 Getting Started
The correct gauge must be used for the rail type. For example a Ri60 gauge will give
incorrect readings if used on a Ri59 rail and vice versa.
When picking a measurement point, it is important to consider the following points as they
can cause an inaccuracy;
Location of welds or branding marks.
Excess loose rust, dirt and grease.
Once a suitable measuring position has been chosen, the gauge can be attached to the
rails. The gauge has 3 locating magnets, as shown in Figure 1, which will allow it to stay
connected to the rail; leaving the users hands free to take the measurements.

Figure 2 shows the mating faces of the rail and the gauge. Once the magnets have
adhered themselves to the faces on the rail, the gauge will hold itself in the measuring
position, as shown in figure 3. The Ri60 gauge shown on the right has a narrower lower
section than the Ri59 and 41GPU gauge to fit the narrower profile of a Ri60 rail.

4.1 Measuring Sidewear
The sidewear measurement is the amount of wear caused on the side of the profile by the
contact of the wheel on the running rail.
To measure the sidewear, ensure the gauge is fully in contact with the rail as shown
previously then the horizontal measuring slide can be adjusted as shown in figure 4.
Figure 4
Once the lower corner of the measuring pin is in contact with the worn edge of the profile,
the measurement can be taken from the sidewear scale on the top of the gauge, as shown
in figures 5 and 6. The sidewear measurement is given as mm worn since the rail was
new.

Figure 5 Figure 6
4.2 Measuring Headwear
Headwear is the deterioration of the top of the profile as a result of the friction between
moving wheel and the rail.
To measure headwear, again ensure the gauge is fully in contact with the rail, please push
the knob or the sliding mechanism directly and not the body of the gauge as this can
cause the gauge to lockup, then the vertical headwear slide can be adjusted until the
measuring pin is touching the top of the rail. The headwear scale on the side of the gauge
will display the measurement for that position.
Headwear is also displayed in mm worn since the rail was new.

5.0 Maintenance
5.1 User Advice
The ABT5210 is a piece of precision measurement equipment. Whilst it has been
designed for use in an engineering environment due care should be taken not to cause
damage to the equipment when in operation, storage or transit. Excessive trauma to the
moving parts of the gauge may invalidate the calibration and lead to possible
measurement inaccuracies.
5.2 Every 3 Months
Visually inspect the ABT5210 for signs of damage. If necessary, contact your local
distributor for help.
5.3 Annual
The ABT5210 must be returned annually for re-calibration to ensure measurements are
within specification.
The condition of all components will be checked at this time and replaced as required.
