| 摘要 |
A synthetic resinous bearing having hydrophobic properties which continuously expel collected waste ink from an ink transfer roller of a printing press. The bearing consists of a molded sleeve of synthetic resinous material such as sintered Teflon or molded nylon which has been impregnated with a compatiable lubricant such as molybdenum disulfide or the like. The bearing includes longitudinally oriented grooves on an inner surface thereof which are not wetted by the flow of waste ink and contaminants, and which provide for continuous discharge of the same during operation of the associated printing press.
