SA - Intramark

Zárt fémházas rugós szimering

SA is reinforced metal cased radial lip seal. The supplementary metal inner ring provides a superior stiffness. This type is not recommended for use in heavy polluted environments. As the static sealing between housing and metallic shell is limited, low viscosity media can “creep“.

Material

NBR 70 SHORE A

carbon steel

spring steel

Media	Mineral oils, Greases
Temperature	-35°C / +100 °C
Pressure	≤0,5 bar
Speed	12 m/s

Product advantages

superior radial stiffness, especially for very large diameters
very good fitting stability avoiding pop-out of the seal
modern lip design provides low radial forces
cost effective for expensive elastomer materials
suitable for use in combination with axial seal (V-Ring)

Application

Transmission systems (e.g. gearboxes), pumps, electrical motors, machineary industry (e.g. tool machines) heavy engineering applications (e.g. mills in steel industry).

Seal housing tolerance

Ød	f8/h11
ØD	H8

Installation

Suitable tool should be used for installation. It is recommended that the installation housing is designed to provide the rotary shaft seal with axial support.
