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|
※ 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.
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.
