Combination needle roller bearings with or without inner rings

The combination of a radial needle roller bearing and a thrust bearing component is a unidirectional or bidirectional bearing

Combination needle roller bearings without inner rings

Set a hardened and ground shaft as the raceway

Combination needle roller bearings with inner rings

Used in applications where the shaft cannot be used as a rolling bearing raceway

NKIA series

The axial load cannot exceed 25% of the radial load

The axial static load safety factor So should be greater than 1.5

Two sets of bearings must be installed opposite each other to support axial loads with alternating directions

NKIB series

The axial load cannot exceed 25% of the radial load

The axial static load safety factor So should be greater than 1.5

The bearing allows for axial movement of 0.08~0.25mm

Narrow inner ring components have larger apertures. If K6 level shaft tolerance is used, the result is a press fit

The two inner ring components must be axially clamped together

NX, NX Z. NKX, NKX Z. NKXR, NKXR Z series

For combination needle roller bearings without inner rings, the shaft must be designed to be used as a rolling bearing raceway, or an IR or LR series inner ring must be used
