Bearing Design – Shapes and Geometries
Embedded round flange bushing
Heavy duty oil-free bearing with embedded solid lubricant base of the high-strength brass alloy.
Available without lubrication
It exhibits an excellent wear resistance in difficult locations of oil film configuration
It has excellent chemical resistance and corrosion resistance.
Embedded Round Flange Bushing is suitable for various circumstances Including high or low load, high or low temperature, with oil or oil lubrication, or even In water.
With its matrix made of high-strength brass, Its hardness doubles that of normal bronze bushings, and the wear performance improves to a large degree, so it is applicable for continued pitching machines, and conveyors of the metallurgy industry. It could also be used in plastic injection machines, in the automatic switch of high-tension electricity, in the luffing and supporting parts of construction machines, hydraulic gate supporter, pulley, drive wheels of water control projects, and also for drying tunnel of paper machines, auto dies, sliding parts for ships unmooring, etc.
