Overview

Technical Parameter

 

JDB-5 steel based embedded bearings are reinforced products with high compressive performance. They can discharge lubricating particles during operation, creating a diaphragm between the shaft and sleeve, which has the advantage of being less resistant to biting than single oil lubrication. They are particularly suitable for supporting parts of lifting machinery.
