generally consist of inner ring ,outer ring, stamping body and cage.It is rely on press and sheet, strip, pipe and profiles, such as external force, to produce plastic deformation or separation, to obtain the required shape and size of the workpiece Stamping of billet is mainly hot rolling and cold rolling steel plate and steel belt. Stamping flange bearing is combines the flange and bearing, is mainly used for various heavy carrying capacity cart wheel, conveyor roller, walking wheels, higher quality requirements, such as industrial and transportation equipment. Stamping wheel can avoid wear and increase the bearing capacity of the bearing.
The difference between stamping bearings and sliding bearings: First of all, from the structure on the surface, stamping bearings is support by stamping body rotation axis of rotation. Thus contact area is a point, the more strength pressing body, the more times you contact point. Sliding bearing is to support the axis of rotation by a smooth surface, thus contact area is a plane. Followed by the movement in a different way, bearing exercise is stamping. Sliding bearing is sliding movement way, and thus the friction form is not completely. the same stamping bearings use convenient maintenance, reliable operation, good starting performance, bearing capacity is higher under the moderate speed.
Installation method: mill hollow shaft installed ram bearing the old-fashioned way is to turn hollow shaft is suitable for the inner diameter of the bearing, Bearing thermal device, bearing parts, bearing outer ring of top cover, top set by front-rear spiral cone bolted on the hollow shaft, to pressure. In the process of grinding operation, front-rear screw barrel, fixed bolt looseness, often caused the roof and the hollow shaft of the displacement, the dust will be empty axis and the gaps between the top cover into the bearing box, make dirty grease, lead to bad lubrication, bearing damage is often happened, to avoid the above situation, the design of a new type of installation method. New installation method: at the site of the mill hollow shaft installed ram bearing diameter add thick, hollow shaft is the cooling of the thin oil and conduct hollow shaft to the bearing temperature drop to 60 degrees below the normal range.
