Needle Axial Cylinder Roller KOYO NAXR15

The JTEKT-KOYO NAXR15 needle-axial cylindrical roller bearing, with an outer diameter of 28 mm and a width of 23 mm, accommodates radial and one-way axial loads in confined spaces.

The NAXR15 needle-axial cylindrical roller bearing combines a radial needle cage with an axial cylindrical roller section to form a ready-to-install bearing unit. This combination allows high radial loads to be supported whilst simultaneously providing axial guidance of the shaft in one direction. Its use is recommended where designs are particularly space-saving, where conventional bearing combinations require too much installation space, and where misalignment needs to be avoided.

What is the NAXR15 needle-axial cylindrical roller bearing suitable for?

It is primarily used in gearboxes, machine tools, swivel drives and lifting equipment where combined loads occur within limited radial installation space. By separating the radial and axial roller guidance, the unit transmits transverse forces without affecting the axial raceway. The assembly is frequently integrated into compact industrial gearboxes or pumps to ensure that bearing arrangements are slim and rigid.

What operating conditions does the naxr15 with a sheet steel cage cover?

The integrated sheet steel cage maintains the rolling elements of both bearing parts at a precise distance and reliably withstands dynamic loads. Manufactured from standard rolling-element bearing steel, the unit is designed for an operating temperature range of –20 to +120 °C. In terms of design and installation, this means it is widely suitable for stationary and mobile machinery, provided that the selected lubricant remains stable within this temperature range.
