>> TSUBAKI POWER - LOCK AS Series

Minimum hub diameter Dn

When Using One POWER-LOCK

Suggested outside hub diameter for two or more POWER-LOCK.
This table shows the minimum hub diameter Dn
Which can tolerate surface pressure P' based on :
B ≥ ( Z x Lt) + Lt Z : Number of POWER-LOCK (2 ≤ Z ≤4)
* The value, d/2 or more, is to be suggested as the guide length C.

Minimum Hub Diameter (Dn in mm) (Conversion)
