Cylindrical roller bearing LFC2234120 For woodworking machinery

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.

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. AST’s cylindrical roller bearings come in the following series with various cage designs and Metric dimensions:

All types of bearings Cylindrical roller bearings Reference Series models:

BEARING TYPE:

NU Series - Are single row cylindrical roller bearings and have two fixed ribs on the                    outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NU Series bearings have no virtually thrust capacity.

N Series - Bearings of N design are single row cylindrical roller bearing and have two  fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the N Series bearings have virtually no thrust capacity.

NJ Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and a fixed rib on the inner ring which can guide the shaft in a single direction (axially).

NUP Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and, on the inner ring, a fixed rib and a support washer. This way they can be used as locating bearings, guiding the shaft axially in both directions.

NN Series - Bearings of NN design are double row cylindrical roller bearing and have three fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the NN Series bearings have no virtually thrust capacity.
