Upper Y axis and radius holder - SPN

The ball holder along with the provided collet can also accommodate circular pins.

1. Loosen the nut to free the ball.

2. 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.

3. 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.

4. 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.

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.

6. Extension

For additional information or to place an order, please contact Rtec Support (contact information provided at the end of this manual).

1. Use four 1/4” button head screws to secure the assembly to the load cell
   and tighten using a 5/32” Allen wrench.
   Then Insert the slip sleeve into the sensor mount.

2. Place the ball holder into the slip sleeve.

3. Mount the Ball Holder onto the suspension in the same manner as onto
   the load cell using a 9/64” Allen wrench.




⚠️
It is recommended to install the ball holder as far as possible into the suspension while making sure that it does not hit the load cell when the suspension is fully compressed.

• Install the load cell on the fast-exchange attachment by fastening the 4 captive screws using a 5/32" Allen wrench.

• The narrow side of the fast exchange plate’s should point to the left of the front load cell as this side will fit into the back of the sliding support.

• The front of the load cell is the face showing the Rtec logo and the unit calibration sticker.

(Optional) With Extension block:

(Optional) You can also use an extension block to reduce the distance between the load cell and the lower setup.

1. Mount the block extension on the exchange plate with 4 4 x 10-32 x 1.250” long screws using 5/32 Allen wrench.

2. Then the adaptor plate mounted on the extension block with 4 x 10-32 x .625” long screws using 5/32 Allen wrench.

3. Install the load cell on the fast-exchange attachment by fastening the 4 captive screws using a 5/32" Allen wrench.

• The narrow side of the fast exchange plate’s should point to the left of the front load cell as this side will fit into the back of the sliding support.

• The front of the load cell is the face showing the Rtec logo and the unit calibration sticker.

 

 

1. Slide in the load cell into the Z stage rack.

Make sure the 4 screws above the rack are removed.
Slide the load cell with its front facing you and the connector on the right.

2. Fasten the 4 securing screws by hands.

3. Connect the ribbon cable. The connector only fit one way.
