Abstreifereinheit für ein Linearwälzlagerelement

摘要

In a linear bearing component (1) which is borne on the running surface (4) of a guide rail (5) and has a wiper (7) on at least one of its frontal sides, one end of which bears on the running surface (4) to retain lubricant in the bearing component (1), there is at least one dosing valve (13) for lubricant is arranged according to the invention on or in the bearing component (1) with its inlet side connected to an intake line and on its outlet side connected to the bearing region (2) or the running surfaces (4). This construction produces a compact stripping unit which prevents soiling from entering the roller bearing and makes it possible to supply defined minimum quantities of lubricant to the running surfaces (4) and the rolling bearing regions (2) in the bearing component (1) without leakage losses.
