Stamping Bearing SB-HA

Stamping Bearing SB-HA
ISUTAMI SB-HA stamping bearing, also known as SB-HA pressed bearing. SB-HA series stamping bearing is mainly composed of inner ring, outer ring, stamping bearing body and cage. It is pressed by external force to obtain the required shape and size. Workpiece stamping billets are mainly hot rolled and cold rolled steel sheets pr strips. The cage and the steel balls are made of bearing steel.

The inner ring of SB-HA series stamping bearing is cylindrical (A) or hexagonal (HA), the inner ring diameter (d) range is 0.317''-0.594'', and the outer ring diameter (D) range is 0.813''-1.26''. The length of outer ring (B) ranges from 0.13'' to 0.25''. The total length (E) ranges from 0.23'' to 0.35''. This series of bearings have convex on one side of the cage, and the convex length (C) ranges from 0.23'' to 0.35''.

Stamping Bearing SB-HA Features

SB-HA series stamping bearings are mainly used in various heavy-duty bearing wheels, conveyor rollers, various industrial and transportation equipment with high quality requirements. The installation method: The normal way of installing the bearing is rotating the hollow shaft to be suitable for the inner diameter of the bearing, and the bearing heat preservation device, bearing component, outer ring of bearing, and the top part is fixed on the hollow shaft by the front and rear spiral setting taper bolts. During the grinding operation, the front and rear screw barrels as well as the fixed bolts loosen, which often causes the displacement of the top plate and the hollow shaft. The dust inserts the gap between the empty shaft and the top cover,then comes into the bearing box, making the grease dirty, resulting in poor lubrication, which often occurs. In order to avoid the above situation, a new type of installation method was designed to prevent bearing damage. New installation method: The diameter of the plunger bearing is thickened on the field of the hollow shaft. The hollow shaft is with the cooled thin oil and introduced to reduce the bearing temperature to 60 degrees below the normal range.
