The metal polymer plain bearing structure is fully homogeneous so all the properties – abrasion , resistance , self-lubrication, low coefficient of friction , resistance to vibration and shock loading – are consistent throughout the entire bearing bushing wall thickness.
VIIPLUS supplies Self-lubricating bearings and provide customer with bearing system designs that meet or exceed their specification.
Metal Backed Bearings :
Sleeve bushing and bearings can be produced into a metallic housing. Use of a self-lubricating Ptfe lining in a metallic housing produces a stiffer bearing that requires significantly less running clearance than other non-metallic bearings. Originally developed to meet the needs of the nuclear power industry, this design is now specified in many other applications.
Metric Journal bearings, split seam bronze backing, works excellent in any pivot or linkage application. For construction and farm equipment, this product is typically used in kingpins, rock shafts, differentials, hinges, pedals and many other pivot points.
