This combined needle roller bearing carries radial and axial loads in a single unit, with a needle roller component paired with an axial ball component for single-direction axial support. Bore diameter is 30.0 mm, outside diameter 42.0 mm, height 30.0 mm, net mass 121.25 g, and the limiting speed reaches 4300 1/min. The cage is of standard design, and sealing is designated Z on one side. Combining two load-carrying elements in one housing reduces axial installation space compared to using separate bearings for radial and axial support. The Z sealing shields the internal raceway from contamination while retaining grease within the bearing, matching the grease lubrication method specified for this series. The single-direction axial component means it takes thrust load from one side only, so the mounting arrangement must be chosen accordingly. The standard cage design guides the needle rollers for stable operation up to the stated limiting speed.
