The INA NKX-XL series is a combined needle roller bearing that handles radial and axial loads in one compact unit. It fits where both directions must be supported but mounting space is tight. MR Industrial Accessories supplies this INA line to maintenance and purchasing teams across the United States and Latin America.

Reading the code is straightforward. NKX marks the combined needle roller bearing series; the number after it is the shaft diameter in millimeters; the -XL suffix indicates the manufacturer's current design. So NKX12-XL fits a 12 mm shaft, NKX20-XL a 20 mm shaft, and NKX35-XL a 35 mm shaft. Bore sizes in this series run from 12 to 40 mm.

Typical installations include machine tools, transmission equipment, pumps, compressors, lifting systems and industrial automation. They also appear in guide rollers and tensioner pulleys. Plants in food processing, petrochemical, textile and metallurgical sectors use them where mounting space is limited and combined loads call for a compact solution.

Selection depends on the radial and axial loads the bearing will carry, the rotation speed and the lubrication method. During mounting, shaft and housing must be aligned and held to the correct tolerances; misalignment reduces service life. Grease or oil can be used depending on the application, and sealing should match the environment. In dusty or humid conditions, extra protection is recommended.

Equivalent combined needle roller bearings from other manufacturers may replace the NKX-XL series when dimensions and load capacity match. Always confirm the complete code and tolerances before interchanging. MR Industrial Accessories supplies INA and can also suggest alternatives so you can compare what fits your equipment.
