Single row cylindrical roller bearings - N19... (K)/N10... (K) series

The spindle of machine tools has extremely high requirements for bearing rotation accuracy. High precision cylindrical roller bearings have high rigidity and load-bearing capacity, while achieving a good combination of high speed performance and small cross-sectional height.

The small cross-sectional height makes the wheelbase smaller during multi axis assembly. Cylindrical roller bearings are an ideal choice for floating bearings because they can compensate for length changes in mating components that are limited by heat.

There are various structures to choose from for high-precision cylindrical roller bearings used in machine tools. Size series 19 and 10 produce single row bearings, while size series 30 and 49 produce double row bearings. The aperture and outer diameter of single row and double row cylindrical roller bearings are identical within each diameter series range.
