Graphite Plugged Oiles Bearing

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.
