JDB 系列石墨镶嵌轴承

Graphite plugged oiles bearing is made of cast bronze alloy base material with special solid lubricants plugged. The base metal withstands high load and the graphite provide self-lubrication. This type of oiles bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. JDB graphite plugged oiles bearing provide a maintenance free bearing solution, particularly for high load, intermittent of oscillating motion.
