Felt shaft seal design
- Thread starter womble
- Start date
Have a look in the SKF bearing catalogue they have a section on SNH plummer block housings where they discuss the felt seals they fit.
Summary:
Can be used for peripheral speeds up to 4 m/s, for speeds greater than this the seal will form a gap and becomes a non-contact seal.Surface roughness should not exceed 3.2 um. For peripheral speeds in excess of 4 m/s a groung finish is recommended.
To protect your shaft from damage you may consider fitting a ground ring. i.e. a sleeve on which the seal can run. The sleeve can be replaced at a much lesser cost than the shaft.
