Features
Cylindrical roller bearings with snap ring grooves are full complement, double row units comprising solid outer and inner rings with ribs, rib-guided cylindrical rollers and sealing rings.
The outer rings have 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.The bearings are available as a light series SL04..-PP and in the dimension series 50 as SL0450..-PP.
Locating bearings
Cylindrical roller bearings with snap ring grooves are locating bearings. These bearings are very rigid and can support axial forces in both directions as well as high radial forces.
Due to their full complement design, they have the maximum possible number of rolling elements and therefore the maximum basic dynamic and static load ratings. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage.
Sealing/lubricant
Sealing rings on both sides protect the running system against contamination and moisture.The cylindrical roller bearings are greased with a lithium complex soap grease to GA08 and can be relubricated via the outer and inner ring.
