High Speed Graphite copper sleeve JDB 4*6*8 Drilling rig bushing

High Speed Graphite copper sleeve JDB 4*6*8 Drilling rig bushing

The JDB4*6*8 bushing answers a simple maintenance problem: pivot points that are hard to reach. Because the solid lubricant is embedded in the brass wall rather than supplied from outside, the bearing keeps working in dusty, wet or high-temperature positions where a grease line would soon clog or dry out.
