For equipment that runs under continuous radial load, the RKB NUB series cylindrical roller bearing is a dependable option. Its cylindrical rolling elements make line contact with the raceways, spreading force across a broad area. This gives the bearing high rigidity and helps it cope with demanding duty cycles in gearboxes, mills and other process machinery.

Reading an NUB part number is straightforward once you know the pattern. The letters indicate the bearing family and its design traits; the digits that follow point to a size or a specific variant. A reference like NUB 18/1000 is a large-diameter size, while NUB 312961 and NUB 313638 are catalogue numbers tied to particular applications. Because each numeric combination can correspond to a different internal design, always quote the complete code when you request a quote.

These bearings appear in steel, cement, mining, and food and beverage plants. They are common in gearboxes, conveyors, mills, presses and material handling systems. Their capacity for high radial loads and resistance to fatigue suit them to non-stop operation, where keeping unplanned downtime to a minimum is a priority.

Selection comes down to a few key inputs: radial load, rotational speed and the surrounding environment. Decide whether the bearing needs to be open, shielded or sealed, based on dust, moisture or particles. The lubricant must match the operating temperature. During mounting, align shaft and housing carefully to avoid extra stress; poor fitting can shorten service life and hurt equipment performance.

Cylindrical roller bearings from different makers often share standard dimensions, but their commercial designations differ. When replacing a bearing from another brand, compare the principal dimensions and load conditions first. Give us the exact part number or the dimensions, and we can point you to a compatible alternative or quote the reference you need.
