(H- /half-moon/half-shaft rings)
Please visit traceparts.com/els/seeger for 3D-CAD models or simply click here:
H-style (half-moon) rings for shafts are the only radially installed locking rings designed in accordance with the Seeger principle of the curved beam of equal strength. The envelopment angle is relatively large due to its resulting high elasticity. The shoulder height of these rings is not as large as in the DIN 6799 versions. These crescent rings are manufactured for shaft diameters up to 55 mm.
