A needle roller bearing uses very thin, long rollers in relation to their diameter —the needles— instead of balls or standard cylindrical rollers. This allows it to support a high radial load with a much smaller available space than any other type of bearing, which is the reason it is chosen.
The SKF NK series needle roller bearing is a compact radial bearing without an inner ring, designed to withstand high radial loads in reduced spaces. It is mounted directly on a hardened and ground shaft, which allows reducing the size of the assembly. It is a common solution in applications where the outer diameter is limited and high load capacity is needed. MR Accesorios Industriales supplies this series in sizes that combine bore diameter and width, such as NK 12/12 or NK 16/20.
The SKF HK series needle roller bearing is a caged needle roller bearing with a machined outer ring and no inner ring. It is used when radial space is limited and high load capacity is needed in a reduced diameter. It is common in transmissions, pumps, power tools and production machinery. MR Accesorios Industriales carries this line as a brand and advises you so that you choose the part number that corresponds to your equipment.
