KS B 1337
A small E-shaped retaining ring pushed laterally into a narrow groove. Used on small shafts (Ø1.5–12 mm) and can be installed without specialized tools.
Practical Notes
- For small shafts (Ø1.5–12mm), pushed laterally into groove. Can be installed without specialized tools.
- Lower retention than C-type — use C-type where axial loads are significant.
