Cover seal with a grooved elastomer outer coating and a partly-coated metal stiffening ring.
Product group: VK
01 = elastomer outer surface
02 = semi-shoulder design
03 = elastomerer outer surface grooved
Seal material: NBR 70, NBR 70
Seal material: FKM 80
Stiffening ring: non-alloy steel according to DIN EN 10139
Areas of application
Cover seals serve the secure sealing of openings for shaft or axle apertures. They are often used in transmissions and for bearing blocks.
NBR: Good chemical resistance to many mineral oils and lubricants. Medium ageing resistance.
Operational application limits
Pressure (MPa/bar): 0,05/0,5
With higher pressures the cover seal should be secured by e.g. a circlip.
NBR: Temperature -30°C to +100°C
It is important to ensure correct installation. It is preferable to use a hydraulic or mechanical press device to press the sealing cap into the housing bore-hole. This grips the sealing cap on a broad area of its outer side so that the pressure is applied as closely as possible to the outside diameter. Please note that the press device should be held at its highest setting for a while. This will reduce the recoil or slanted positioning of the sealing cap to a minimum.
Generally speaking, elastomers are suitable for storage. They remain almost unchanged in their properties for years, provided that certain minimum requirements regarding storage conditions are observed. These are described in DIN 7716 and ISO 2230.
The seals must be stored stress-free, i.e. without tension, pressure or other forms of deformation.
