Cylindrical roller bearing SL series with single seal or double seals are double row sealed bearings. One row of rollers and outer ring can be assembled as one non-separatable part. Cylindrical rollers are guided by the rib of inner ring. Outer ring has a solid rib, two locating slots on the outer surface with a lock ring which easily locate the bearing axially. The bearing housing width is usually smaller than that of the bearing to reduce required room in the axial direction. As locating bearings, this type of bearing can accommodate axial load in both directions with bigger width, it can also accommodate upsetting momet.
Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.


Full complement cylindrical roller bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.
The bearings have solid outer and inner rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Double row full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings. The bearings do not permit any skewing between the inner and outer ring.

1. The cylindrical roller bearing is the combination of 2 machined and polished grooved raceways(inner&outer rings), guilding a number of appropriate cylindricalrollers as the rolling elements, with a cage or full complement.

2. This type bearings are designed to carry heavy radial loads at high speed.

3. Series: NU, NJ, NUPG,N, NN, NNU, NCF, NJG, NNCL, NNCF and so on

4. Types: Single Row Caged CRB,Double Row Caged CRB, Multi-row Caged CRB, Singel Row Full Complement CRB,Double Row Full Complement CRB, Multi-row Full Complement CRB, and so on

5. Cylindrical roller bearings with cage have high radialload carrying capacity, operating at high speed. Full compliment cylindricalroller bearings can accommodate even higher radial loads, but at low and moderate speed.
