NJ422+HJ422 Cylindrical Roller Bearing
The NJ422+HJ422 bearing is a roller bearing with an inner diameter of 110 mm , an outer diameter of 680 mm, a width of 65 mm. It typically uses P0,P6,P5 grade precision tolerances and together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Bearing name: SKF NJ422+HJ422 bearing
Cylindrical roller bearings
In bearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.
Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools. Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings.
There are different types designated as NU, NJ, NUP, N, NF (for single-row cylindrical roller bearings), NNU, and NN (for double-row cylindrical roller bearings depending on the design or absence of side ribs). The outer and inner rings of all types are separable .
