MATERIAL: Spring band steel C75 or similar grades, or chromium nickel steel 1.4310. The double-wound retaining rings DSB, DSW and DMS, Fig. 7, 8, 9, are valuable additions to the regular, single -wound retaining rings.

ADVANTAGES:

  • Roundness of the closed ring over 360 ensures strong contact with the groove bottom and continuous support around the circumference.
  • Reliably retained in the groove, even under high axial load.
  • Well balanced during rotation.
  • Absolutely free from material defects.
  • DMS double-wound rings with locking feature to resist centrifugal forces can be used at shaft speeds that are beyond the range of DSW rings. Diameter range for DMS: 45-310mm.
Double wound laminar locking rings FK7, are supplied to order with single-sided or double-sided removal recesses, as shown in Fig. 3
APPLICATION EXAMPLES:
These retaining rings are used whenever parts need to be fixed axially, for example, in transmissions, on agricultural machinery and construction equipment, in shipbuilding and engineering, aerospace and automotive applications and for winches, pulleys, wheels, roller bearings, vertical drive shafts, etc.
