Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23. The bearings have solid outer rings with two ribs, while the inner rings have one rib. The inner ring can be removed and this gives easier fitting of the bearings. Disc cages or spacers prevent the cylindrical rollers coming into contact with each other during rolling.
X-life
Many sizes are supplied in X-life design. These bearings are indicated in the dimension tables.
Bearings of X-life quality have a lower roughness Ra and superior geometrical accuracy of the raceways than comparable designs that are not X-life. As a result, the load carrying capacity and life of these bearings is higher while maintaining the same dimensions. In certain applications, a smaller design of bearing arrangement can therefore be used if necessary.
