Locating and non-locating bearing positions
SNL housings can be used for both the locating and non-locating bearing positions.
For smaller sizes, the housings are machined standard for bearings in the non-locating position. Bearings in the locating position as well as CARB toroidal roller bearings must be secured in the housing on both sides with locating rings. Appropriate locating rings are listed in the product tables for bearings on an adapter sleeve (with standard seals), for bearings on an adapter sleeve (with oil seals) and for bearings on a cylindrical seat.
Housings from sizes 3076, 3168 and 3264 upwards are supplied in two designs:
- Housings with the suffix F have a bearing seat that matches the bearing width. These housings should be used for spherical roller bearings in the locating position and CARB toroidal roller bearings.
- Housings with the suffix L have a bearing seat that is wider than the bearing. These housings should be used for spherical roller bearings in the non-locating position. The possible axial displacement is at least 20 mm.
