Needle roller / angular contact ball bearings
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. FUSHI supplies these bearings without seals in the following
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.

NKIA series
Needle roller / angular contact ball bearings in the NKIA 59 series ( fig. 1 ) can accommodate axial loads in one direction and can, therefore, locate the shaft in one direction only. For short shafts and where changes in length as a result of thermal expansion are relatively minor, two bearings in the NKIA 59 series can be mounted back-to-back ( fig. 3 ).
NKIB series
Needle roller / angular contact ball bearings in the NKIB 59 series ( fig. 2 ) can locate a shaft in both directions. Depending on the bearing size, the axial clearance is between 0.08 and 0.25 mm. To facilitate mounting, the bearing has a two-piece inner ring. When mounting the inner ring, it is important that the two pieces are mounted immediately adjacent to each other without any gap between them.
