SNL and SE plummer (pillow) block 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. For information about mounting rolling bearings, refer to the SKF bearing maintenance handbook or skf.com/mount.
The grease fitting kit provided with SE housings contains torque values for the cap bolts and data for initial grease fills.
Torque specificationsCap 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 housingSome 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. To simplify mounting and make alignment more accurate, lines indicating the centre of the bearing seat and housing bore axis are cast into the housing base (fig. 1).
