THB LSL series Cylindrical roller bearings with a disc cage (series LSL) or with spacers (series ZSL) are of a single row, self-retaining design and correspond to dimension series 23.

Cylindrical roller bearings NJ23..-E and spherical roller bearings 223..-E1 have the same design envelope as LSL1923 and ZSL1923.

LSL1923 and ZSL1923 features:

- semi-locating
- have two ribs on the outer ring and one rib on the inner ring
- have very high radial load carrying capacity
- can withstand high shock loads and vibrations                                                                          - low frictional torque and the low level of heat generation, high limiting speeds.
