3. Application
Engineering Machinery Dry Sliding Bearing Grease Lubricated POM Bushings are widely applied in engineering machinery, port machinery ,hydraulic machinery etc.
4. Advantages
This series of sliding bearing recommended for applications involving intermittent operation or boundary lubrication with good load capacity and anti-wear. It is machinable for the thicker of POM.The bearing surface carries a [attern of circular indents which should be filled with grease on assembly initially,the cyclical greasing can greatly extension the bearing service life.
