This type of Load Cell is composed of a singular part, which makes it easier to use. Inside this Load Cell are two piezo sensors, one measuring Fz and the other measuring Fx.
In this example of standard assembly, you can see on the front side of the 200N load cell a sticker which is the calibration unit of each axis force, fz and fx, necessary to read correct value based on those reference value.
The 100N suspension assembled on it is used to limit the vibration induced by the sample during testing. There are several variations of suspensions depending on the maximum load it can be effective on.

- Position yourself at the right frame of the MFT and place the back of the arm (the pivot base)against the frame, making sure the base of the arm is pressed against it.
Refer to the alignment guide on the side of the instrument to determine
the correct mounting holes.
the correct mounting holes.
The level of the friction arm depends on the configuration.
ex: For the block-on-ring configuration without heating chamber, use
positions 5 and 7.
positions 5 and 7.
- Attach the friction arm to the instrument using the 1.125-inch screws and washers to secure the arm. (1/4-20 x 1.000” BM310340-09). Hand-tighten initially; fully tighten with the 3/16” Allen Key after final adjustments.
Mount the Spring Assembly
- Use a 5/64" Allen wrench to mount the springs to the front and back of the Fx-1D arm.
- Ensure proper tension and secure the spring assembly.
Attach the Load Cell Cables
- Connect the Sensor Cable
- Connect the Fx Arm Cable to the Fz Load Cell
- Raise the Fz-1D Load Cel
Pin/Ball holder preparation
The ball holder along with the provided collet can also accommodate circular pins.
- Loosen the nut to free the ball.
- Insert the adjusting pin into the holder, then the ball.
Provided for standard test: Ball, .250" (1/4") (6.350mm) Dia
E52100 100Cr6 grade 25 Alloy Steel.
- Hold the holder vertically, so the ball is resting on the pin.
Using a 1/8" Allen key, fasten the screw inside the holder to slightly push the ball.
- Once the ball is retracted enough, fasten the nut to secure it.
For preliminary testing: The ball may be reused by rotating it to expose a unworn contact surface.
For final measurements: It is recommended to employ a new ball for each test to ensure accuracy and reproducibility.
For final measurements: It is recommended to employ a new ball for each test to ensure accuracy and reproducibility.
Extension holder
- Use the extension only in particular cases where the ball holder cannot reach the sample.
- Increasing the ball holder length can negatively affect test results, especially in reciprocating tests. Whenever possible, use the load cell extension block instead.
(to reduce the distance towards the sample)

Ball holder Spring Setup
Sleeve, insulator cap and the adaptor are placed on the top of the holder.

For more information
A suspension is used to limit the vibration induced by the sample during testing. There are several variations of suspensions depending on the maximum load it can be effective on. .
It is recommended to select a suspension system with the closest higher load rating to the expected load.
For example, if you realize a test at 150N, you would need to use the 200N suspension. By doing so, you will mitigate the vibrations the most.

Self-Adjusting Block holder preparation
The self-leveling block holder will ensure proper contact during the test.
- Firstly ,loosen the 2 tightening screws using /16” Allen key.
- Slide in the block sample into the block support
Avalaible ASTM Rtec Block Catalog
ASTM: D3704, G77, G176, D2714, D3704, D2509
- Level the block sufficiently into the holder.
- Tighten the securing screws on each side.
Installing the montage into the arm
- Unscrew the thumb screw/knob present on the front of the arm
You can now open the securing block and insert the holder.
- Insert the holer onto the arm and align the slot on the sleeve with the alignment pin on the arm.
The flange of the insulator sleeve must be positioned towards the top of the block holder
For the block holder: Make sure that the notch matches the extrusion of the block holder
For the block holder: Make sure that the notch matches the extrusion of the block holder
- Slide the sleeve into position and loosely secure it.
Level the arm
Use the built-in level on the 1D arm to ensure the arm is mounted horizontally.
- Manually press the arm so the ball holder contacts the sample, as the level must be evaluated when the pin/ball is in contact with the surface.
- Slightly loosen the tightening screw/knob.
- Adjust the arm position up or down until the level indicator shows proper alignment.
- Once the 1D arm and block holder aligned and level, tighten the sleeve
securely.
The collets must be fully inserted into the arm
- The ball holder and arm can remain suspended
Confirm the assembly is secure and aligned
Please verify this important aspect of the setup, as they can be easily forgotten or ignored, possibly affecting the quality of the testing and result.
