Overview

INA NKX17-Z-XL Needle Roller / Axial Ball Bearing combines a radial needle roller bearing with an axial ball bearing function. It is suitable for gearboxes, clutches, and compact drives that must support radial load and one-direction axial load within limited radial space.

A radial needle roller section and an axial ball-and-cage assembly are integrated into one unit. Cover or washer configurations can be selected according to lubrication retention and mounting requirements.

Key features

Supports radial and axial loads in one unit
Compact radial design
Saves space around gears and clutches
Reduces the number of assembly components

Typical applications

Gearbox shafts
Clutches and transmissions
Small electric drives
Rotating sections of automation equipment

Selection guidance

Check radial-to-axial load ratio, axial load direction, washer configuration, lubrication, and mounting space.
