PURPOSE:To feed grease continuously while to discharge used grease reliably by fitting a flinger for pressure feeding used grease onto the rotary shaft while providing a grease storage chamber communicating with the grease supply path and the used grease storage chamber while having a float valve in the bearing box. CONSTITUTION:An annular flinger 16 for performing pumping as the shaft rotates is fitted over a rotary shaft 11 while adjoining to the inner ring of bearing 2. A used grease storage chamber 14a is provided radially in same axial direction with the flinger 16 in a bearing housing 14 constructing a bearing box 13. While a lubricant grease supply path 15a reaching from the outercircumference to the endface of bearing 2 and a tubular bottomed grease storage chamber 15b having one end communicating with said supply path 15a and the other end communicating with the used grease storage chamber 14a are provided on the bearing cover 15. A reciprocal float valve 18 is provided in said chamber 15b to prevent over packing of grease. |
