Product introduction Main parameter Details Picture

　　This type of bearing is a special bearing, is specially designed for the steel rolling mill press down mechanism, bearing no cage full of rollers, allowing a very low speed, axial load capacity is very large, in order to meet the requirements of the steel rolling mill press down mechanism work, the top ring of this type of bearing is processed into convex spherical TTSX000 type (4297/000 type) or concave spherical TTSV000 type (4397/000 type), to ensure its Aligning performance, with other matching shaped end contact uniform, in the press down mechanism relative to the bearing axis when a certain tilt can ensure that the shaft bearing force uniform.

　　This kind of bearing is made after strict matching, rollers and other parts interchangeability is poor, each set of bearings should be used independently, and the rollers between the set and the set cannot be mixed when installed.
