Abstract

　転がり軸受から分離した形で取り扱いが可能な転がり軸受のグリース溜り部品と、このグリース溜り部品を組み込んだグリース溜り付き転がり軸受を提供する。このグリース溜り部品６は、内輪１、外輪２、およびこれら内外輪１，２の軌道面１ａ，２ａ間に介在した複数の転動体３を有する転がり軸受５に対して、軌道輪である内輪１および外輪２のうち、回転しない固定側軌道輪２に隣接して配置される。グリース溜り部品６は、内部がグリース溜り１２となる環状の容器部１０と、この容器部１０から突出して前記固定側軌道輪２の軌道面２ａが形成された周面に沿って前記軌道面２ａの近傍まで挿入される環状の軸受内挿入部１１とを有する。この軸受内挿入部１１は、内部がグリース７の流路１４となり、先端１１ａに円周方向に延びるスリット状のグリース基油滲み出し口１５を有する。このグリース基油滲み出し口１５は、取り外し自在な封止部材１８で封止する。
