Centerless Stone Lapping Machine

for machining of inner ring raceway and rib face for single and double-row taper roller bearings

Standard application range : OD 265 - 528 mm x Breadth 28 - 300 mm x Raceway taper angle Max 90°, Rib face angle 7.5° - 32°

HN-600TF

Main Features

  • Machining of inner and outer ring raceways and rib faces for large single- and double-row tapered and cylindrical roller bearings
  • As the machining range of the tooling is all limited and shared, the need for specialized tooling due to differences in workpiece size is reduced (excluding rib face machining)
  • One-cycle automatic machine
  • Outer diameter roller centerless support system
  • Each axis is servoed, allowing for easy setting of angle adjustment, etc.
