Internal retaining rings are inserted with the aid of
pliers to pass down a shaft bore and then released to
spring outwards into a groove. A tapered section ensures
even pressure when fitted.
The nominal size refers to the bore through
which the retaining ring is designed to pass.
• Inch Series: N1300-0025 (0.250" bore)
• European Metric DIN series: D1300-0250 (25mm bore)

Suitable for a wide range of typical internal applications.
Acts as a rigid shoulder within a bore.
Provides resilient end play take-up, acting
like a spring to fill the gap in any
tolerances in an assembly to "take up the
slack". Reverts to a rigid retainer if the
applied load is such that the ring is
Provides rigid end play take-up.
Used to take up any tolerances in
an assembly but, unlike to 1301,
will not flex when in place.
The chamfered end expands into the mating
groove where the ring "rides down
and forward" to contact the
High clearance diameter. Designed to
give low shoulder height and used in
applications where the relatively
larger 1300 lugs may not be acceptable.
Smaller sizes in particular are also
better dynamically balanced than
standard 1300 types.
Design based upon 1300 series but with
increased thickness for added strength
when shock loads are present. Also used
where high static loads are combined
with radiused or chamfered abutment (due
to its increased resistance to conical
deformation. Contact contact
Additional lugs provide
additional abutment area. Used to maintain
full contact with retained parts
having large chamfers or radii which would
otherwise contact the ring only at the lug
and "beam." This ensures more even load
