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.

NKIS 50

The NKIS 50 is a single‑row, machined‑ring needle roller bearing with inner ring, designed for applications where radial space is tight but high radial load capacity and stability are required. Its dense complement of fine rollers guided by a steel cage — combined with a sturdy outer ring with flanges — delivers excellent stiffness, smooth rotation, and even load distribution under heavy-duty or continuous operation. Because the bearing comes complete with its own inner ring, it's a suitable choice in situations where the shaft surface isn’t hardened or ground to function as a raceway, ensuring proper bearing seating, easier installation, and long service life when properly lubricated.
