Rolling-contact bearing design for "Increased degree of protection" (option)
Improved sealing of the bearing units to prevent dust and water from getting in can be achieved
by positioning a grease chamber ahead of the actual bearing unit. Although the same grease
is used in both cases for reasons of convenience, a distinction is made here between
"lubricating grease" and "sealing grease" because of their different functions.
Layout
The spent lubricating grease collects in the space between the bearing housing and the outer
bearing cap. The latter also forms the sealing grease chamber with the labyrinth sealing ring
(optional). The second lubricating nipple containing the grease duct for pressing in the sealing
grease is also located in the outer bearing cap. The chamber is sealed off from the space
where the lubricating grease collects by a V-ring or a V-ring and felt ring combination which
prevents the sealing grease in the chamber from penetrating into the lubricating grease
collecting space. During operation, the sealing grease in the chamber slowly runs out via the
labyrinth and seals it, additionally removing dust from inside and around the outside of the
labyrinth ring.
