While the sheet metal material and punched holes in auto seat systems, and cold rolled steel sheet, have great size tolerance, the smallest possible gaps are needed in seat systems in order to minimize noise.
In order to resolve this kind of problem, auto seat design engineers are making increasingly use of EPB3 plastic plain bearings and PCB plastic clip bearings made by CSB.
EPB3 plastic plain bearings are made from composite materials consisting of superior engineering plastic reinforced with high-strength fibers to provide a substrate with high compressive strength. A special solid lubricant is implanted in the plastic substrate among the fibers to meet the need for long-term oil-free lubrication. The outstanding strength and abrasion resistance of EPB3 plastic plain bearings can satisfy the high strength and abrasion resistance needs of auto seat adjustment mechanisms, and can undergo electrophoresis processing at 180°C without any problem.
PCB plastic clip bearings are made from EPB3M plastic sleeve material and have an open-type double-flange design. The inner and outer diameter can be freely adjusted depending on the actual size of the punched holes in the sheet metal material, which can greatly reduce sheet metal fabrication costs. The open-type design makes installation very convenient; the bearings can be installed directly by hand without any other auxiliary equipment, which further reduces manufacturing costs. The double-flange design uses abrasion-resistant material to separate the two sides of the sheet metal and other adjoining surfaces, which reduces noise when seats are adjusted. In addition, the double-flange design can ensure that the bearings will not be lost during the shipment of semi-finished products or in a subsequent electrophoresis process.
