Incremental Measuring Head Distance Plate Recommendation
Recommendation Distance Plates for Incremental Measuring Heads
If you want to mount the incremental measuring head directly onto the bearing outer ring, a distance plate is required. To enable the measuring head to measure at the correct position, the distance plate must be used to adjust two distances: DP-L and DP-H.
DP-H: Distance plate height (vertical direction) | DP-L: Distance plate length offset (horizontal direction)
| Bearing Model | DP-H [mm] | DP-L [mm] |
|---|---|---|
| AXRY 150 | 5 | 4.56 |
| AXRY 180 | 5 | 4.62 |
| AXRY 200 | 5 | 4.60 |
| AXRY 260 | 7 | 4.07 |
| AXRY 325 | 7 | 4.10 |
| AXRY 395 | 7 | 2.29 |
| AXRY 460 | 9 | 2.65 |
| AXRY 580 | 14 | 4.53 |
| AXRY 650 | 20 | 2.63 |
Installation Notes
- The bearing outer ring has M4 threads with 51mm spacing
- The distance plate secures the measuring head via M3 threads with 16mm spacing
- The distance plate must be provided by the customer
Notes
Important Reminders
- Data listed in this table are reference values; final specifications are subject to the official myonic product catalog
- MI system bearings are based on the NGX series, H2 (shaft side height) is increased by 10mm measuring ring
- The measuring head can be integrated into the surrounding structure or mounted directly on the outer ring using a distance plate
- Contact myonic application engineering team for special configurations or customized designs
