WZZG NKIA5909 ( 1 PC ) Complex Bearings 45*68*30mmNeedle Roller Angular Contact Ball Bearing NATA5909 NATA 5974909
WZZG Angular contact combination needle roller bearings NKIA5909
WZZG needle roller / angular contact ball bearings combine a radial needle roller bearing with an angular contact ball bearing. The radial loads are accommodated exclusively by the needle roller bearing and the axial loads exclusively by the angular contact ball bearing.
These low cross section bearings can operate at high speeds and accommodate heavy radial and light axial loads.WZZG supplies these bearings without seals in the following two series:
NKIA series, bearings can accommodate axial loads in one direction
NKIB series, bearings can accommodate axial loads in both directions
Bearings in both series are separable i.e. the inner ring can be mounted separately from the outer ring, rolling element and cage assemblies. However, the inner rings in the NKIB series are not interchangeable with those from another seemingly identical bearing. Therefore, the bearings must be kept together as supplied.
Depending on the application, needle roller / angular contact ball bearings can be grease or oil lubricated. In the case of grease lubrication, both the needle roller and angular contact ball bearing should be filled with the same lubricant prior to mounting.
