  • COMPONENT

ADVANTAGE

The advantage of TJR spindle bearing

Company A Company B
Radial-axial preloading bearing Taper roller bearing Cross roller bearing
Can bear heavy cutting in the horizontal and verticaldirections Can bear less heavy cutting Can only bear light cutting
  • Dynamic load: High
  • Superior to the others in static rigidity; high durability for heavy cutting
  • Dynamic load: Medium
  • Only for Light cutting
  • Superior to cross roller bearing in rigidity; but not enough durability for heavy cutting
  • Dynamic load: Low
  • Only for Light cutting

EXPLANATION

※ Cutting Force + Weight of Workpiece + Weight of 3-jaw Chuck + Weight of Flange Disk = Total Weight

  • Radial-axial bearings deliver less deformation δ and sustain heavy work pieces.
  • Normal bearings create more deformation δ and sustain light work pieces.

COMPONENT

Radial-axial bearings have an axial component and a raidal component. The axial component comprises an axial cylindrical roller and cage assembly, an outer ring, L-section ring and shaft locating washer and is axially preloaded after fitting. The radial component is a full complement preloaded cylindrical roller set. The outer ring, L-section ring and shaft locating washer have fixing holes. The unit is located by means of retaining screws for transport and safe handling.
