Simmerings, A-type sealing rings for sealing shafts

Dear Customers,
due to the May 1st and 3rd holidays and the related company May trip, our company will be closed on Friday, May 2nd.
We kindly ask you to place your orders well in advance and invite you to shop again on Monday, May 5.

Simmerings, i.e. type A sealing rings, are one of the most popular rotary seals used for radial sealing of shafts. They are made of rubber and stiffened with a metal insert or enclosed with a metal cover. They can work in grease, oil, fuel or water at pressures up to 0.1 MPa in the temperature range from -30 to +110 °C. The outer cylindrical surface of sheet steel or elastomer seals the ring statically in the seat.

Simmerings have an elastomer sealing lip pressed with radial force towards the shaft surface, in some versions there is a dust-proof lip protecting against dust and other solid impurities. Sealing rings have a wide variety of designs and are made of various materials to ensure their reliability in various operating conditions. There are the following types of simmerings:

Type A - base type
Type AD - a type with an external cylindrical corrugated surface
AE type
Type AF - type with increased lateral compensation
Type AH - type used at low rotational speeds
Type AO - type used for overpressure up to 0.3MPa
Type AOD - type with an external cylindrical corrugated surface and an additional sealing lip
Type AOF - type with increased lateral compensation and additional sealing lip
Type AOH - type used for overpressure up to 0.3MPa and low rotational speeds.
