| How to Understand - |
|
Smallest dia through which
the given head has to pass |
|
Depth of clearance for Cover
plate (If there is no Bottom or Head clearance, extra special Anvil Design can
be provided) |
|
Length at which measurement is req. (Add
extension if required) |
|

The purpose of the Bush is to
protect the Anvils when sliding through deep holes. For normal applications
this bush is not required. When measuring deep holes user should ensure the
alignment of Gauge axis and Bore axis. For measuring deep holes Spherical
contact points are preferred because they allow certain amount of deviation in
Gauge axis without affecting accuracy. |
| RECOMMENDATION: |
Three point system is
recommended.
Two point system also available as an option. |
| For standard measuring
lengths |
See Table
|
| More than one extension can be
used. For extension lengths available |
See Table
