BRUCKNER LIVE CENTERS
S, SG, SKOP, AND SKOPG TYPE
 

 

Types S, SG, SKOP, SKOPG

Common Technical Features:
  • Housing - Drop-forged (tensile strength of the high-quality material used:  approx. 1,000 N/mm2
  • Taper Shank without Bore - Therefore it is not weakened.  Thus high moments of deflection can be obtained without any permanent bend to the large taper diameter.
  • High Concentricity accuracy - Guaranteed by the test report.
  • Large-dimensioned precision roller bearings, free from clearance - for taking up the radial and axial forces.  No bearings in the taper shank.
  • Seal Ring - Protects the bearings from dirt and coolant.
Type S, SG centerpoint 60°

Technical Features:
  • Concentricity Runout
    - Type S  max. .005 mm (.0002")
    - Type SG  max. .003 mm (.0001")
  • Two Series
    - slim design for light-duty work
    - with stronger bearings for normal high duty service
  • With thread for draw-off nut
  • For circular grinding operations we recommend the use of our supplementary seal (see below)
Applications:
  • Type S:  for copy-turning, NC-turning, roughing, finishing, fine-turning
  • Type SG:  for turning and grinding operations demanding high accuracy
