| 6. The combination with a ball bearing of a lubricant distributing member of rigid oil-permeable material operatively associated with each ball, and soft, absorbtive members of large oil-carrying capacity in feeding relation to the distributing members. 9. The combination with a bearing having rolling, load-carrying members, of a lubricating device comprising a rigid, porous oil-conducting member of small saturation content in distributing contact with each load-carrying member and soft, highly-absorbent members of large oil-carrying capacity in feeding relation to the conducting members. 10. The combination with a bearing having rolling, load-carrying members, of a lubricating device comprising a hard porous member of small oil-absorbing capacity in oil-distributing relation to each load-carrying member, and a soft, porous member of large oil-absorbing capacity in oil-feeding relation to said hard member. | ||
