Adaptor both for manually operated or power driven are not included.

Internal clamping sleeves with double taper are suited to internal clamping of pre-machined parts. Because these have tapers and slots at both ends, the clamping sleeve is able to open in various different ways and securely hold workpieces in the bore which have cylindrical faults.

Use:
for internal clamping

Advantages:

  • double clamping effect
  • return effect
  • clamps slightly tapered bores


Running concentricity (truth):
0,01

Hardness:
The internal clamping sleeves are made from special spring steel. They are hardened – depending on the design – to approx. HRc 48 up to HRc 56.

Taper of sleeve mandrel:
The taper of the sleeve mandrel should be 15’ (one-sided) flatter than the taper angles given in the tables. This frees the clamping sleeves on release.
