FSNL split pillow block housings

The FSNL is part of the SKF split pillow block housing range: a cast iron housing that separates into two halves. You open it to install or remove the bearing without taking down the shaft or the drive, which matters on equipment that needs frequent maintenance. Shaft diameter, the bearing it holds and the way it attaches to the structure drive the selection.

In SKF part numbers such as FSNL 218, FSNL 511-609 or FSNL 516-613, the FSNL prefix names the series and the number is the housing size, not the shaft diameter. When there are two numbers, as in 511-609, each one is a bearing size; both bearings share the same outside diameter and fit the same housing. For a replacement, give us the complete part number and the bearing mounted in it.

Conveyors, fans, pumps, mixers and continuous-process machines use these housings. Since the halves come apart, you can replace the bearing or check lubrication without moving the shaft, so downtime stays short. End covers and locating rings are added to suit the sealing and axial location the application calls for.

We carry SKF in this line. For a quote, send us by WhatsApp the part number marked on the housing. If you can't read it, give us the shaft diameter, the bearing it holds and a photo or sketch of the base, and we'll quote the right part number along with the accessories the assembly needs.
