Description
This combined needle roller bearing carries radial loads through its needle roller set and axial loads in a single direction via the integrated axial ball bearing component, built to DIN 5429. Bore diameter is 30.0 mm, outside diameter 42.0 mm, height 30.0 mm, net mass 144.16 g, and the limiting speed reaches 5000.0 1/min. The bearing uses a standard cage and features a Z-type shield along with an end cap enclosing the assembly. The combined design allows radial and one-directional axial loads to be supported within a single, compact envelope, saving axial space compared to separate bearing arrangements. The shielded construction retains grease lubrication and reduces contamination ingress, making the unit suited for installations where the shaft position is fixed in one axial direction and where reduced maintenance access is expected. Grease lubrication is specified as the intended lubrication method for this configuration.
