Specialized machined needle roller bearings, used for equipment miniaturisation and high load support.

The machined ring needle roller bearings are characterised by high rigidity and high precision. They are assemblies of a machined outer ring, containing needle rollers and a cage.

Thanks to the high rigidity of the outer ring, these bearings are suitable even for light alloy housings. The needle diameter is comparatively small, which allows for installation in places of high radial load, but low cross-sectional height. Therefore, a reduction in the size and weight of the produced equipment is possible. Two types are available – with an inner ring and without an inner ring, for when the shaft is used as the direct raceway surface.

JNS produces corrosion-resistant stainless needle roller bearings and inner rings. They are applied in medical, food, packaging, fibre and chemical equipment as well as in other places where high corrosion resistance is required. Since the outer ring, inner ring, and the rollers are made from Martensite stainless steel, high precision  in machining is achieved. The available sizes are the same as the JNS standard products. The stainless types are available in the same sizes as the standard types.
