Solid Self-Lubricating Bearing

JDB-1 Solid Self-Lubricating Bearing

JDB-1 Solid Self-Lubricating Bearing, at high force brass substrate. Mosaic graphite or MoS2 solid lubricant is a high-performance solid lubricant. It broke through the general bearing lubrication film to rely on limitations. During use, heat through friction with the shaft friction of solid lubrication, forming oil, lubrication powder coexist excellent condition, both to protect the shaft is not worn, and the solid lubricant properties eternal. Its hardness copper sleeve than twice as high wear resistance is also twice as high.
The product has been used in metallurgy continuous casting machine, the train bracket, rolling equipment, mining machinery, shipbuilding.
