SKF Needle Roller Bearing NK 12/16, 12 mm ID, 19 mm OD, 16 mm Width, Steel Cage, 30000 rpm Speed NK 12/16

The SKF NK 12/16 needle roller bearing is a high-performance rotary bearing designed for demanding industrial environments. Featuring a 12 mm inside diameter and 19 mm outside diameter with a 16 mm race width, this needle bearing offers an ultra-compact solution for fast rotating shafts operating at speeds up to 30,000 rpm.

This bearing's steel roller construction combined with a sheet steel cage provides excellent wear resistance and friction-free operation even under heavy static loads up to 12 kN and dynamic loads of 9.13 kN. The design includes two internal flanges for easy guidance into annular grooves and lubrication holes to facilitate regular maintenance and regreasing, consequently enhancing bearing life and reliability.

The NK 12/16 bearing handles axial displacement in both directions, making it versatile for machines with shifting axial loads. Its compact profile reduces the cross-sectional height, ideal for machinery with constrained space requirements. It is recommended for shafts with hardened and ground raceways accounting for long-term durability and smooth performance.

Common applications include automotive engineering components, construction equipment, and heavy plant building machinery requiring robust yet compact bearing solutions. The bearing's hardened steel rollers resist corrosion and wear under continuous use.

The design facilitates high-speed operations up to 30,000 rpm without compromising stability. Its lightweight construction (16 grams) minimizes stress on linked mechanical joints. Lubrication points ensure easy maintenance and prolong lifespan.

Two internal flanges allow smooth fitting into precise groove placements. Capable of supporting substantial static and dynamic loads for reliable mechanical performance. Its compactness suits machines with tight spatial constraints without losing robustness.

This bearing is made in Slovakia and follows SKF’s high-quality manufacturing standards. It comes unlubricated, allowing users to apply lubrication that best fits their specific operational conditions.
