Produktdata

Operational application limits

De operasjonelle bruksgrensene som teperatur, omkretshastighet og trykk bestemmes av de valgte roterende akseltetningen. Som regel dekker WSH R driftsparametrene for alle standard roterende akseltetninger.

Teknisk informasjon

Glideflaten for akseltetningen er et viktig maskinelement i det roterende tetningssystemet. Det må derfor oppfylle en rekke tekniske krav for å oppnå god tetningseffekt og lang levetid.

Applications

WSH R shaft repair sleeves are used to repair grooved or worn rotary shaft seal sliding surfaces, e.g. in drive technology. They offer a cost effective alternative to replacement or the laborious reworking of the worn shaft as they are simply pulled over the worn sliding surface.

Deep grooves can result in the original rotary shaft seal dimension having to be replaced with a rotary shaft seal with a smaller inner diameter because the original diameter has been significantly reduced by the reworking of the shaft. This problem with the grooved shaft in the sliding surface area can be solved quickly and easily using the WSH R, without having to dismantle and rework the shaft or use a rotary shaft seal of a different size.

Naturally, WSH R can also be used as original equipment for machines, aggregates or plants to avoid the complex, costly and in some cases also difficult processing of the sliding surface on the shaft.
