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.

Numerous sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables.

Bearings of X-life quality have, for example, lower roughness R_a and higher geometrical accuracy of the raceways than comparable designs that are not X-life. As a result, for example, they have higher load carrying capacity and longer life for the same dimensioning. In certain applications, this means that a smaller bearing arrangement can be designed.

In the case of bearings of TB design, the axial load carrying capacity was significantly improved through the use of new calculation and manufacturing methods.

Optimum contact conditions between the roller and rib are ensured by means of a special curvature of the roller end faces. As a result, the axial contact pressures on the rib are significantly minimised and a lubricant film capable of supporting higher loads is formed. Under normal operating conditions, wear and fatigue at the rib contact running and roller end faces is completely eliminated.

In addition, axial frictional torque is reduced by up to 50%. The bearing temperature during operation is therefore significantly lower.

By agreement, series SL1850 is available starting from a bore diameter d = 180 mm in the form of the TB design .

Bearings SL0248 (designation to DIN 5 412-9: NNCL 48..V) and SL0249 (designation to DIN 5 412-9: NNCL 49..V) are non-locating bearings and can support radial forces only.

The bearings are held together in handling and transport by a transport and mounting retaining device on the outer ring. This retaining device remains in the bearing and must not be subjected to axial load.

The outer ring without ribs can be axially displaced in both directions in relation to the inner ring. The inner ring has ribs on both sides.

The cylindrical roller bearings are of an open design.

Oil or grease lubrication is possible. For lubrication, the outer ring has a lubrication groove and lubrication holes.

The semi-locating bearings are available as SL1850 (dimension series 50). They can support not only high radial forces but also axial forces in one direction and can therefore guide shafts axially in one direction. They act as non-locating bearings in the opposite direction.

The bearings are held together in handling and transport by a transport and mounting retaining device on the outer ring. This retaining device remains in the bearing and must not be subjected to axial load.

The inner ring can be axially displaced in one direction by the dimension “s” stated in the dimension table.

The cylindrical roller bearings are supplied in an open design.

Oil or grease lubrication is possible. The bearings can be lubricated via the end faces as well as via a lubrication groove and lubrication holes in the outer ring.

Bearings SL0148 (designation to DIN 5 412-9: NNC 48..V) and SL0149 (designation to DIN 5 412-9: NNC 49..V) are locating bearings. These bearings can support axial forces from both directions as well as radial forces.

The outer ring has ribs on both sides, is axially split and held together by retaining rings. The inner ring has an additional central rib. The retaining rings must not be subjected to axial load.

Cable sheave bearings (cylindrical roller bearings with snap ring grooves) are locating bearings. These bearings are very rigid and can support moderate axial forces in both directions as well as high radial forces. They consist of solid outer and inner rings with ribs, rib-guided cylindrical rollers and sealing rings.

The outer rings have snap ring grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and held together by a rolled-in steel strip.

Cylindrical roller bearings with snap ring grooves are available as a light series SL04..-PP and in the dimension series 50 as SL0450..-PP.

In the case of cable sheave bearings, the running system is protected against contamination and moisture by sealing rings on both sides.

Open locating bearings can be lubricated with oil or grease. For lubrication, the outer ring has a lubrication groove and lubrication holes.

Cable sheave bearings are greased using a lithium complex soap grease to GA08 and can be lubricated via the outer or inner ring. Arcanol LOAD150 is suitable for relubrication.

Open full complement cylindrical roller bearings are suitable for operating temperatures from –30 °C to +120 °C.

Cylindrical roller bearings with snap ring grooves are suitable for operating temperatures from –20 °C to +80 °C, restricted by the grease and seal material.
