Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
HZK cylindrical roller bearings are available in a variety of cage types suitable for different scenarios, including EM brass cages, ETVP black nylon cages, FAG process products, ECML integral cages, and E steel cages.
There are different types designated NU, NJ, NUP, N, NF for single-row bearings, and NNU, NN for double-row bearings depending on the design or absence of side ribs. HZK’s cylindrical roller bearings come in the following series with various cage designs and Metric dimensions.
