Four row taper roller bearing- Catalog 1/5

Product introduction ：The invention relates to a four-row tapered roller...

Product details：

The invention relates to a four-row tapered roller bearing for machine mountings, with an inner ring of two-part design axially and on outer ring of single- or multi-part design axially, with an inner and/or an outer tapered-roller row, being supported in each case by an inner ring part. In order, firstly, to confer a large supporting width on the bearing and, secondly, to ensure as optimum as possible and as uniform as possible a loading of the rolling bodies in the form of the tapered rollers, the tapered-roller rows are arranged in an O-arrangement, and the roller axles or the respectively adjacent outer and inner tapered rollers of the two respectively adjacent outer and inner tapered-roller rows are arranged at an inclination in such a manner that those lines of influence of the tapered rollers which characterize the pressure angles intersect in the region of the axis of rotation of the tapered roller bearing. In addition to other advantages, this bearing can be produced more cost-effectively and, with regard to production quality, more reliably than known four-row tapered roller bearings.
