What is the bearing measurement range (minimum to maximum)?
A/ The following gives the standard bearing measurement ranges:
- ADM-101 Anderon meter drive unit for small-diameter bearings: 681X to 6906
- ADM-512 Anderon meter drive unit for medium-diameter bearings: 693 to 6309
- ADM-7010 Anderon meter drive unit for large-diameter bearings: 608 to 6024
We also provide products for other measurement ranges. Please contact our company.
How can I set a standard for determining the acceptability (pass/fail) of bearings for a nonspecific application?
While it's not possible to set a pass/fail standard for bearings for which no application is specified, you can set a standard by determining the relationship between the product using the bearing and bearing quality. To do this, obtain measurements from bearings using an Anderon meter and divide the bearings into groups based on the Anderon value and the presence/absence of scratches. Then, install them into products and evaluate the acceptability (pass/fail) of the products by bearing group. Compare the pass/fail results of bearing groups and products to set a pass/fail standard for the bearings.
What's the advantage of using a pusher?
The test bearing becomes "integrated" with the Anderon meter during measurement to form a single vibrating system. Any change in a component element alters the Anderon vibration of the bearing. The pusher and bearing retainer are important component elements. It’s possible to press against the test bearing with a hand, without using a pusher, during measurements, but the results can vary depending on how you press against the bearing, and the measurements may be non-reproducible.
Why are there three bands (L, M, and H)?
The Anderometer was the precursor of the Anderon meters. When the Anderometer was manufactured in the United States in the 1940s, the band was divided into L, M, and H (low, medium, high). This has remained unchanged.
An essay introducing the Anderometer at the time concluded that dividing the band into three to five segments was the optimal approach. The frequency component of Anderon vibration is distributed over the entire band. The preference for 3-band instruments is likely based on a balance between analytical performance and practical considerations.
How much axial pressing force can be applied?
The following axial pressing force can be applied:
- ADM-101 Anderon meter drive unit for small-diameter bearings: Up to 50 N
- ADM-512 Anderon meter drive unit for medium-diameter bearings: Up to 100 N
- ADM-701 Anderon meter drive unit for large-diameter bearings: Up to 1,500 N
