ZARN Series Lathe Spindle Bearings

ZARN Series Lathe Spindle Bearings

ZARN Series Lathe Spindle Bearings Components:

 

ZARN Series Lathe Spindle Bearings including a thickened outer ring, needle roller cage assembly, needle roller inner ring, two thrust cylindrical roller cage assemblies and two inference shaft rings.
Thefore, ZARN bearing is equivalent to a combined bearing of one set of needle roller bearings and two sets of thrust cylindrical roller bearings.
Moreover, the centers of the two thrust cylindrical roller bearings coincide with the centers of the needle roller bearings.

Lathe Spindle Bearings Features:

1. Double direction needle roller/axial cylindrical roller bearings.
2. High speed. Limiting speed can reach 3000-8500rpm for oil lubrication.
3. High precicion. The axial runout accuracy of ZARN series bearings can reach 1μm
4. The bearing can withstand greater radial/axial load and has higher radial/axial rigidity
5. Compact structure and small size
6. Wide practicability, easy to install
