Type K rings with lugs: DIN 983 (shaft) and DIN 984 (bore)
DIN 983 (shaft) and DIN 984 (bore) define retaining rings with lugs, known as type K. The lugs, spread around the circumference, support the component. They are used mainly to secure bearings, with protection against radial deformation, and fit DIN 471 and DIN 472 grooves.
For shaftsDIN 983, AK series, DIN 471 groove
For boresDIN 984, JK series, DIN 472 groove

How to specify
- Shaft or bore. DIN 983 for shafts (AK) and DIN 984 for bores (JK).
- Nominal diameter (d1). Of the shaft or bore; the groove is the same as DIN 471 or DIN 472.
- Load. Check the permissible axial load in the datasheet.
