Four Row Tapered Roller Bearings
The four row taper roller bearing is a most commom radial roll bearing.A bearing with such structure has a high bearing capacity and can bear the combined load which is mainly consisted by the radial load.Its radial loading capacity is 2.5-3.5 times that of a single-row bearings. It can bear bith very high radial and axial loads. Compared to a four-row cylindrical roller bearings, it has a relatively low speed due to the restriction of its structure.The four-row tapered roller bearing can bear axial loads in double direction, so it can be used as a bodorectional thrust bearing.Boundary dimensionsBasic load ratingsDesignationsMassLimiting
