BR4C bronze base rolled bushing
BR4C bronze base rolled bushing is a thin wall bearing made of bronze material with uniform and orderly oil injection holes. After assembly, it is filled with lubricating grease and then used with end face seals. The bearing has the advantages of large oil storage, convenient installation and small design volume, and can replace the copper sleeve, which can greatly reduce the cost.
At present, the product has been used in conveyors, elevators, winders, leveling machines and other occasions with medium load and low speed.
