Abstract
A protective element for a sealing arrangement having at least one sealing ring has an annular bottom having an inner side and a radially outer side. A mantle portion is connected to the radially outer side. A cylindrical portion is connected to the radially inner side and has a central axis. The mantle portion and the cylindrical portion extend in opposite directions relative to the annular bottom. The cylindrical portion has a circumferential end face extending at least over a portion of the circumference at a slant relative to the central axis. Such a protective element prevents adhering of dust particles to the shaft and penetration of dust particles into the sealing arrangement.
