What does it mean if a DFS60 has a number as hollow shaft size (e.g. DFS60x-T5xx...)?

What is it?

This is a DFS60 with a plastic hollow shaft. The benefit of this version was that it had a isolated shaft and the maximum rotating speed was higher (up to 12000 rpm).

The disadvantage was that the plastic hollow shaft was not very stable. Therefore we decided to phase it out.

Can we still order it?

Versions that still have a part number, can still be ordered but we do not create new part numbers and we do not promote them anymore.

Replacement?

If you need a DFS60 with isolated shaft, than you can use a PEEK sleeve. (Higher rotation speeds are not very often needed).

More information?

The sizes of the hollow shaft were:

  • "T3": through hollow shaft 3/8"
  • "T4": through hollow shaft 10 mm
  • "T5": through hollow shaft 12 mm
  • "T6": through hollow shaft 1/2"
  • "T7": through hollow shaft 14 mm
  • "T8": through hollow shaft 15 mm

The old datasheet can be found attached.
