Mounting

SNLN 30 housings must be mounted properly using the appropriate tools and state of the art mechanical mounting methods. All the associated components must also meet certain basic requirements (→ Specifications for shafts and housing support surfaces).
Mounting instructions for each housing are provided with the seal pack, except for housings from size 3024 to 3032 with seals in the TSN 2(00) series. For these housing/seal combinations, mounting instructions need to be ordered separately. For information about mounting rolling bearings, refer to the SKF bearing maintenance handbook or skf.com/mount.

Torque specifications

Cap bolts should be tightened to the torque values listed in the product tables for bearings on an adapter sleeve and for bearings on a cylindrical seat. For information about attachment bolts, refer to Attachment bolt recommendations.

Pinning or supporting the housing

Some load conditions may require the housing to be pinned to its support surface or a stop to accommodate loads acting parallel to the housing support surface (→ Additional housing support).
Recommendations for the position and size of the holes to accommodate dowel pins are provided in the product tables for bearings on an adapter sleeve and for bearings on a cylindrical seat. Dimples cast into the housing base mark the recommended positions.
