Centerless Stone Lapping Machine

for machining of inner and outer ring raceway for single and double-row taper and cylindrical roller bearings

Standard application range :
- Outer ring : OD 250 - 600 mm x Breadth 20 - 410 mm x Raceway taper angle 0° - 90°
- Inner ring : OD 250 - 600 mm x Breadth 20 - 410 mm x Raceway taper angle 0° - 90°

HN-600E

Main Features

  • Machining of inner and outer ring raceways for large tapered and cylindrical roller bearings
  • Machining of raceways for single- and double-row bearings
  • One-cycle automatic machine
  • 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
  • Outer diameter roller centerless support system
  • Easy changeover

    • Work piece: Taper Roller Bearing Inner Ring
