IMPORTANT: The sealing lip of the radial shaft seal is highly sensitive and must not be kinked. Do not touch the sealing lip with your fingers.

NOTE: Support sleeve (2) is included in scope of delivery. 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. The support sleeve (2) remains in the radial shaft seal and is used as a slip sleeve in the installation described later.
