NKI 1516

The NKI 1516 is a machined‑ring needle roller bearing with inner ring, providing a hardened raceway independent of the shaft — which means it can be used even if the shaft is not specially treated. It offers excellent radial load capacity while maintaining a compact cross‑section, making it ideal for gearboxes, small motors, and industrial machinery requiring low-profile bearings. The needle‑roller and cage assembly ensures smooth rotation, good rigidity, and reduced friction under load

NKI 2530

The NKI 2530 belongs to the same series of needle roller bearings with inner ring; it is designed for heavier‑duty applications where larger shaft diameter is needed while still offering compact radial space usage. It is suitable for larger industrial gearboxes, conveyors, heavy machinery shafts, and other systems where strong radial load support and compact bearing profile are required.
