NOTE:

Radial shaft seal may only be supported with a "support sleeve".

If the radial shaft seal (1) is stored for longer than six months without the support sleeve (2), its operational reliability can no longer be guaranteed and it must not be reused.

IMPORTANT:

The sealing lip of the radial shaft seal is highly sensitive and must not be kinked under any circumstances.

Do not touch the sealing lip with your fingers.
