Description

This combined needle roller bearing carries both radial and single-direction axial loads within one housing seat, reducing the axial space needed compared to a separate bearing arrangement. Bore diameter is 50.0 mm, outside diameter 62.0 mm, height 35.0 mm, and net mass 288.35 g. The design follows DIN 5429, includes an end cap, and the limiting speed is 3300 1/min. The Z sealing shields the roller and ball complement from contact contamination while retaining grease lubrication inside the unit. A standard cage guides the needle rollers, and the single-direction axial component means the bearing supports axial load acting from one side only, so the mounting arrangement must account for this when combined with a separate bearing carrying axial load from the opposite direction.
