CONSIDER EXTRA-THIN TYPES OF ELASTIC STOP ® NUTS
FOR BEARING RETAINING APPLICATIONS
THESE ARE THE BENEFITS AND ECONOMIES ACHIEVED BY USING
REGULAR ELASTIC STOP NUTS FOR BEARING RETAINING APPLICATIONS:
1. Lower total manufacturing costs result from tooling
and machining standard SAE threads on shaft in
place of special extra-fine bearing locknut threads.
2. Lower manufacturing costs result from elimination of
cross-drilling of shaft for cotter pin holes or milling a
slot in shaft for a tab washer.
3. Easier assembly; a stop nut can be clamped-up as
tightly as you specify, in a single operation. Selflocking
nut does not require re-adjustment to permit
cotter pin location.

4. Nylon insert’s non-destructive locking grip does not
gall or in any way distort costly shaft threads.
5. Removal and reuse is a simple matter of wrenching
off-on.
6. There is no safety device for the workman or maintenance
worker to forget. The ESNA ® “safety” device
is built in.
7. The unavoidable “play” in a cotter-pinned adjustment
accelerates wearing of the gears, bearings or other
fastened members. Service life is extended and
bearing wear is minimized as a result of the constant
clamping action maintained by the nylon insert.
An ESNA bearing-type nut applied to the output shaft
on a heavy -duty truck transmission. It replaced a
castle nut and cotter pin fastening.
