ZSB

| Comparison of the 107H
and the small ball ZSB107J shows that the ZSB has more smaller balls which helps improve
bearing stiffness. |
Barden/FAG engineers developed the ZSB small ball angular contact shielded series spindle
bearings to allow machine tools to operate at higher running speeds (up to 20% more)
while maintaining optimum workpiece finish characteristics. The small ball feature of
the ZSB series allows a greater number of balls to be used, increasing bearing stiffness,
which leads to improved machining accuracy at higher speeds.
Barden's ZSB series offers optional
integral shields which reduce the chances of bearing failure through contamination
and prolong lubricant life when bearings are grease lubricated. Shields are available
as an option on all sizes.
The inner ring outside diameter land is removed from one side and the outer ring bore
diameter land is removed from the opposite side. This allows for optimum exposure and
flow through characteristics for air/oil lube systems, and increased storage areas for
shielded grease lubed bearings. Also available in HS(S) and HC(S) types.
