Live Centers


BRUCKNER High-Performance Live Centers with spring-loaded centerpoint

  • The Principle - The spring loading compensates for workpiece thermal expansion and variation of workpiece length.  The bearings of the live center and the machine are thus protected

Type LR

 Type LD Type LRE, LDE

Spring loaded for workpiece thermal expansion - WITH pressure indicating colored rings

Spring loaded for workpiece thermal expansion - WITHOUT pressure indicating rings

Female centerpoint, spring loaded center, with or without pressure indicating rings. Available with 7 standard types of interchangeable tips 


BRUCKNER High-Performance Live Centers
  • Head Bearings:  The Design - When loaded, every center's taper shank deflects at the point where the Morse Taper emerges from the tailstock.  BRUCKNER mounts all the bearings in the head.  Thus the unit centerpoint/bearings is placed in front of the deflection diameter.  Therefore the taper shank bending stress is not transmitted to the centerpoint.  Result: No premature wear of individual bearings due to running on their edges.

BRUCKNER High-Performance Live Centers for Heavy Duty Machining
  • Heavy Workpieces - The live center is an important element in the force system of the heavy-duty machine tool.  It plays a decisive role in the final machining result.  The BRUCKNER design is especially suited for the high requirements of heavy-duty machining.  The maximum admissible load depends on the taper diameter.  Therefore we offer a choice of two different series: Load carried only on the taper, or load carried on the taper with additional tailstock-sleeve support.
Type M, MG, AM, AMG Type MR, MRG Type MZ, MZR

Centerpoint 60º, 75º, or 90º - available with threaded body for a draw-off nut (version A)
Centerpoint 60º, 75º, 90º - with tailstock sleeve support ring
Spring loaded with pressure indicator on body - Centerpoint 60º, 75º, 90º


BRUCKNER High-Performance Bullnose Live Centers
  • Robust and Precise - Our bullnose live centers have a sturdy cylindrical roller bearing where the load is heaviest.  Combined with large axial and radial deep-groove ball bearings this design allows high loads together with high concentricity and long life.  For circular grinding operations BRUCKNER bullnose live centers are market leaders.  This work requires bullnose centers with stability reserves for good grinding results.
Type ZA, ZAG

Great for circular grinding operations - available with or without thread for draw-off nut
