Split spherical roller bearings are principally used where the replacement of unsplit spherical roller bearings would require costly additional work, involving the removal of gears or couplings, the dismounting of drives or the dismantling of shaft power trains.
The use of split spherical roller bearings reduces the downtime of machinery and plant.
Split spherical roller bearings have a cylindrical bore. The inner ring, outer ring and cage with the roller set are split in half. The split bearing rings are held together by screws. The internal design of most split spherical roller bearings was carried over from our proven spherical roller bearing E1, the only difference is that some larger bearings have a rigid central rib on the inner ring. Split spherical roller bearings have the normal tolerances of unsplit radial bearings and the normal internal clearance of unsplit spherical roller bearings with a cylindrical bore.
Full Complement Cylindrical Roller Bearings These single and double row bearings have full complement rolling element sets. The rolling elements are guided by ribs on the bearing rings. Since they have the maximum possible number of rollers, full complement bearings have extremely high load carrying capacity and high rigidity. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage. The bearings are available as non-locating, semi-locating and locating bearings.
Full Complement Cylindrical Roller Bearings with snap ring grooves Due to the grooves in the outer rings, the bearing rings can be axially located using retaining rings. The bearings are therefore highly suitable for cable sheave bearing arrangements. Sealing rings on both sides of the bearings protect the running system reliably against contamination and moisture. Since it has the maximum possible number of rollers, the full complement design has extremely high load carrying capacity and high rigidity and is suitable for compact designs.
Needle Roller and Cage Assemblies Needle roller and cage assemblies are single or double row units comprising cages and needle rollers.
Since their radial section is no greater than the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with a very small radial design envelope to be achieved. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted.
Drawn Cup Needle Roller Bearings Drawn cup needle roller bearings with open ends and with closed end are units comprising thin-walled drawn outer rings and needle roller and cage assemblies. Drawn cup needle roller bearings with open ends are also available in full complement versions. The majority of the bearings are single row designs.
Drawn cup needle roller bearings with open ends and with closed end are available in open and sealed versions. Due to the thin-walled outer drawn cup and the absence of an inner ring, drawn cup needle roller bearings have an extremely low radial section height. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted. If shoulders, snap rings etc are not used for axial location, the housing bore can be produced easily and economically.
