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, the inner rings are designed with one rib. The inner ring is removable and thus allows easier mounting of the bearings. The disc cages or spacers prevent the cylindrical rollers from coming into contact with each other during rolling.
Various sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables.
Bearings of X-life quality have lower roughness Ra and superior geometrical accuracy of the raceways than comparable designs that are not X-life. As a result, these bearings 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.
