FEY Labyrinth Sealing Rings

Protect components in dirty and abrasive environments up to 700oC

greasing - application examples

Option 1

Grease relief bores, arranged vertically to the groove base, four of each groove circumferentially distributed at 90o. The bore diameter depends on the groove width. The grease pressed by the bearings can flow in next to the rings or can flow out upwards under the rings. 

Option 2

Grease relief bores, arranged horizontally to the groove base, four of each groove circumferentially distributed at 90o. The bore diameter should be between 3 and 5mm. The grease pressed by the bearings can flow out upwards under the rings (groove base diameter) and next to the rings.

Option 3

This greasing option is a combination of 1 & 2 above. A ‘grease chamber’ is placed between the 2 sealing ring sets, this will act as a grease reservoir in the groove and therefore optimise the sealing effect.
