1400 Series: Basic
Suitable for a wide range of typical external applications. Provides a rigid, load-bearing shoulder on a shaft.

1401 Series: Bowed
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 flattened. Contact Application Support for details.

1402 Series: Beveled, Chamfered
Provides rigid end play take-up. Used to take up any tolerances in an assembly but, unlike to 1401, will not flex when in place.  The chamfered end expands into the mating groove where the ring "rides down and forward" to contact the retained part.  Contact Application Support for details.

1408 Series: Inverted
Reduces clearance diameter. Designed to give low shoulder height and used in applications where the relatively larger 1400 lugs may not be acceptable.  The fitted profile is "tidier." Smaller sizes in particular are also better dynamically balanced than standard 1400 types.

1460 Series: Reinforced
Design based upon 1400 series but with increased thickness (and increased depth in the case of the N1460 series) for added strength when shock loads are present and also to resist conical deformation when, for example, large abutment radii are present.

2100 Series: Increased Abutment
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 distribution.
