Bearing housings

The housing holds the bearing and anchors it to the machine frame, so it sets how concentric and rigid the assembly is and how easy it is to mount and remove. There are two broad groups: split housings, which open so you can service the bearing with the shaft left in place, and one-piece housings such as pillow blocks and flange units. Selection begins with the bearing, then how it fits on the shaft and how the housing is bolted down.

Designations differ from brand to brand. In SN-type split pillow block housings you will see part numbers like SN506 (NTN), SNT 528 (Timken) or SNS3036-H-D (FAG); the number tells you the housing size. Link-Belt, Rexnord, Sealmaster and Dodge are listed by product line: Medium Duty 200 and Split Housings for Link-Belt, PT Select and ZMC2080MM for Rexnord, PN Gold and USRB5000 for Sealmaster, and SL and SCM for Dodge. SKF shows up as LHCA 150 / 20 and SHL 60/V21, and Browning as FBE920x 1 1/2SR. Only the full part number identifies the exact unit.

Before you pick one, pin down the bearing it will carry, the shaft diameter, how the bearing mounts (cylindrical or tapered bore), how the housing is anchored and the operating environment. Typical duties are conveyors, gearboxes, pumps, fans, mills, mixers and line shafts. If you need to reach the bearing without pulling the shaft, go with a split housing; where space is tight, a pillow block or flange unit makes installation simpler.
