Install the Linear Reciprocating Drive
Technical specification:
Proper alignment of the sample on the reciprocating holder helps maintain its rated life.
The load factor applied to any reciprocating system is still the main factor determining its rated life.
The reciprocating mechanism can withstand high loads when used within its designed operating conditions. However, the general mechanical principle described below cannot be avoided.
rated life: the total travel distance that 90% of linear guides can reach
X₀ → Maximum X Differential Position
The maximum offset of the load along the X-axis relative to the center of the drive.
This value accounts for the total stroke displacement.
This value accounts for the total stroke displacement.
Y₀ → Maximum Y Differential Position
The maximum offset of the load along the Y-axis relative to the center of the drive.
Load
It depends on the position of the applied force. Refer to the following document for guidance on determining the maximum allowable load per test.
For example, if the X.Position is 0 mm and the stroke is 10 mm, then X₀ = 5 mm.
This information and the maintenance assessment should be taken into consideration during high-load testing procedures.
- Adjustable Stroke length: 0.1-30 mm
- Frequency: 0.1-80 Hz ( 80 Hz @ 1 mm, 60 Hz @ 2 mm, 20 Hz @ 25 mm).
- The maximum allowable frequency is determined by the current stroke length. The respective limits must not be exceeded.
- Some reciprocating drives are not fully covered by this specification, e.g., SPN04316 – up to 15 Hz. Please refer to your packaging list if unsure or unaware of this information, or contact Rtec Support for assistance.
- (Option) LVDT Linear Encoder Range: 25.4 mm (+/- 12.7 mm); Resolution: 1 um
When using the reciprocating system in combination with the LVDT, the stroke length limitation becomes 25.4 mm. The stroke length cannot be accurately measured or guaranteed beyond this value.
- Position the reciprocating drive on the base.
Ensure that the black connector underneath the module is properly aligns and connects with the green connector on the base.

Machine manual control allows the user to manually control the displacement of the X, Y, Z stage and the module installed.
For X, Y and Z, the 2 first buttons move the axis in the direction of the button whenever pressed. The last button (“Distance”) allows the user to move the axis by a specific distance in a positive or negative direction.
By dragging the slider on the right of the window, you can uncover other parameters.
- Vel: It is the displacement value (in mm/s) of the X, Y platform when moving the X, Y platform using the machine manual control upper window.
- Move Abs XY: This part will be available if the tester is homed. It allows the user to move to a specific absolute position of the X, Y platform. This position is defined based on the home position.
The button on the left refreshes the current XY position.
You can enter the X and Y absolute position in the free space and then press ”XY Move” to move to this absolute position.
In the current version, the move Abs XY may have some problems, it is recommended to use the “Distance” of manual control explained previously.
- Teach Offset: This parameter is used to teach the offset between the testing and imaging position of the tester. This is the part where you can do the inline imaging calibration. It will be introduced further in Part 2.2.2.4.1.
- Move Offset: This parameter is used to automatically move between the testing and imaging position.
- TEST => IMG: The platform goes from the test position (where the sample is located below the load cell) to the imaging position (where the sample is located below the imaging head)
- IMG => TEST: The platform goes from the imaging position (where the sample is located below the imaging head) to the test position (where the sample is located below the load cell).
Make sure that you are using the right move offset type. If you are in the test position and use “IMG => TEST”, the platform will go in the wrong direction. It will be stopped and the initial position will be lost.
The “Move Offset” needs to be calibrated in order to efficiently move between the testing and imaging positions. The calibration will be introduced further in Part 2.2.2.4.1.
On the right side of the manual control window should be the manual module control. This window allows the user to manually use the module installed.
By clicking on the “ON” button, you can turn the motor off.
Next to it should be possible to modify an intrinsic parameter of the module: frequency (Hz), speed (RPM) etc…
The two buttons at the right start (Left one) and stop (Right one) the manual movement of the module.
The “Distance” button on the far right allows you to set a number of rotations / cycles.
Test Control Window
On the test control window, you can control the homing (Left), Start (Middle) and Stop (Right) of the recipe.
Add Steps
Introduce the components
Save the destination file
- In the DATA LOGGING Window Select the file format (or leave Default).
- Click OPEN LOG FILE.
- Name and save the data file into a folder.
- Define the Sampling Rate depending on the Drive velocity defined in the recipe.
For more information
Part 1: File Management
In the file management window, it is possible to manage where the file containing the data will be stored.
Firstly, select the file format:
- .CSV: Recommended file format, can be opened with Excel and most data analysis software (including Rtec software).
- .BIN: Older file format, can be opened with Rtec analysis software.
Then, you have the choice between saving the data as a singular file or as part of a project.
- Specific file: You can click on “Open File Location”, the file resulting from the test will be stored in the selected folder.
- Project: You can save a file as part of a project.
First, click on “ Project Folder” to select the storage location of the project.
Then, in “Sample Name [Subfolder]”, it is possible to create a subfolder where all the tests of a specific sample are stored.
Finally, in “File name: Run-XXX-“, you can change the increment for every specific test of a sample.
Part 2: Data Acquisition Parameters
The maximum sampling rate of the system is 10kHz. Default value is 1kHz.
You have the possibility of changing the Sampling Rate (Hz) and number of data points averaged.
- Sampling rate: It corresponds to the amount of data points taken in each second. The higher it is, the bigger the resulting file will be.
- Averaging: This number is used for the moving average filter. It corresponds to the number of data points averaged for each point recorded in the final file. The higher this number, the less the variations will be seen in the results.
It is recommended to take a sampling rate between 10x and 100x the primary motion frequency (f0) of the system:
- Rotary/Upper Rotary/BOR:
- Reciprocating/VoiceCoil:
- For example, for a test at 1000 RPM, f0=16.67 Hz. Thus, it would be recommended to set the sampling rate to:
- For basic shape visualization: 10*16.67 = 167Hz.
- For balance between vibrations and shape: 30*16.67 = 500Hz
- For vibration and outliers focused analysis: 100*16.67 = 1667Hz
When such calculation is not appropriate, we recommend to use a sampling rate of 1-10kHz.
We recommend to set the average number of points between 1 and 5 for reciprocating motions. For other motions, a setting between 5 and 10 is more appropriate.

4Ball alignement
- Do a coarse approach manually using the jogbox.
- While doing it, you can visually ensure that the upper holder reach the ball without colding with the inner ring of the nut.
You can move the 4-ball container by hand to observe the degree of X–Y movement allowed by the self-centering platform.
The self-adjusting platform will guarantee the fine alignment on the initial approach and during the test.
If the ball holder reaches or contacts the inner edge of the nut, even within the self-displacement range of the plaftorm, the homing position is misaligned. In this case, please proceed to the homing correction step.
Setting a new X Y Position as Home
The homing must have been done. The ball holder is manually aligned to the lower drive’s center.
- Go to the Configuration Window.

Rotary Test
Simple rotary test

- Sensor.Reset Fz: 1
- Sensor.Reset Fx: 1
- Y.Position: Your test radius value
- X.Position: 0
- Disengage Z: ✅
- (Optional) rename it : Reset Sensor & Position
X axis Position must be at 0 for rotary tests
Most Rtec-Instruments load cells are designed to measure friction along the X-axis (Fx).
Because of this, it’s important to always set Y to a nominal value and X = 0. This ensures that all friction forces appear only along the X-axis, where the sensor can detect them.
If you adjust the radius along X, the friction force will shift to the Y direction (Fy). In that case, the load cell will not be able to measure it correctly, and it could even cause damage to the sensor.

Rtec Instruments ASTM G99 Test Protocol
This procedure is based on the ASTM G99 Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus.
The full standard is available from ASTM International (www.astm.org). This document is not a substitute for the official ASTM G99 standard.
The full standard is available from ASTM International (www.astm.org). This document is not a substitute for the official ASTM G99 standard.
Summary of Standard
This test method covers a laboratory procedure for determining the wear of materials during sliding using a pin-on-disk apparatus.
Materials are tested in pairs under nominally non-abrasive conditions. For the pin-on-disk wear test, two specimens are required.
One, a pin or ball that is positioned perpendicular to the other, usually a flat circular disk. The tester causes stationary pin/ball to press against the rotating disk at a known force and speed. During the test COF, friction, wear etc. parameters are measured and reported.
