Gamma-Rings
For the external sealing of rotating shafts

Gamma-Rings serve as pre-sealing for the outer sealing of rotating shafts against contamination, granules, dust, oil, grease, liquids etc. and com bine the function of a contactless centrifugal gasket as a gap seal as well as an axially fitting rubber sleeve gasket. The sleeve consisting of different rubber qualities is produced with a corresponding radial pre-stressing integrated into the housing. The device built in that way is then attached to the shaft with a press fit, so that the rubber lip rests on the counter surface.

Our Gamma rings are available as sealing rings in various housing materials such as anodised sheet steel, nickel-plated sheet steel or stainless steel. The different elastomers create a multitude of possible combinations for these seals.

Advantages of the gamma rings

protection of the sealing lip against mechanical impact
low mounting width
good centrifugal effect
low requirements with regards to the counter surface (surface hardness, tolerance of thrust surface)
straightforward mounting
no additional retaining fixture necessary
improved longevity for bushings and shaft seals

Applications of the Gamma-Rings

Gamma-Rings are mainly used in combination with shaft seals. They are used as modular upstream sealing element to seal against dirt, dust, oil and water splashes from the outside.

Fields of application of the gamma rings

Gamma-Rings have been successfully used for many years in drive engineering and in mechanical engineering, e.g. with electric motors, transmissions, pumps, motor saws, drive shafts, wheel hubs and axles, in agricultural machinery, construction machinery, machine tools, rolling bushing housings and washing machines.

Designation	Pressure	Temperatur Range	CIRCUMFERENTIAL SPEED
NBR	Construed for pressure-free operation	-40°C +120°C	<_ 12 m/s
FPM	Construed for pressure-free operation	-20°C +200°C	10 m/s

The above mentioned parameters are maximum values and must not be placed simultaneously side by side as they are dependent on the other operating parameters.
