The needle roller bearing uses very thin, long rollers in relation to their diameter —the needles— instead of balls or standard cylindrical rollers. That lets it carry a high radial load in a much smaller space than any other type of bearing, which is why it is chosen.

The SKF NA series comes with complete inner and outer rings, unlike other needle designs that have only a cage with needles or an outer ring. The designation combines the series number with the coded inner and outer diameters; suffixes such as RS indicate a seal on one or both sides.

It is used in gearboxes, gear pumps, steering mechanisms, guide rollers and any point in a machine where little radial space is available but the load is significant. It is common in compact equipment where a ball bearing or a cylindrical roller bearing of the same capacity does not fit.

Mounting is more demanding than with a ball bearing: since it cannot absorb misalignment, the shaft and the housing must be well aligned and have the correct fit tolerance, because a misaligned needle roller bearing is destroyed quickly.

Across manufacturers there are equivalent needle series with the same inner diameter, outer diameter and width dimensions, although the variety of designs —with or without an inner ring, with or without a seal— is greater than in other bearing types. It is best to confirm the exact design before ordering the replacement.

Send us the full part number or the three dimensions (inner diameter, outer diameter and width) by WhatsApp and we will confirm the available equivalent. MR Accesorios Industriales has the SKF NA series listed.
