Bearing Housing Selection — Quick Reference (ISO 113 / DIN 504)
Bearing housings mount + protect bearings — fixed mounting point locating the bearing relative to shaft + machine frame. Selection turns on housing style (pillow / flange / take-up), material (cast iron vs pressed steel), insert series, and shaft orientation.
| Housing Style | Mounting Orientation | Best For |
|---|---|---|
| Pillow Block (P / UCP) | Horizontal shaft, vertical-load mounting | Conveyors, fans, general shaft support — workshop default |
| 2-Bolt Flange (FL / UCFL) | Bolted through machine wall | Vertical or horizontal shaft through wall/plate |
| 4-Bolt Flange (F / UCF) | Bolted through machine wall — heavier load | Heavier-duty wall mount |
| 3-Bolt Flange (FB / UCFB) | Bolted through wall — compact | Light-duty wall-mount applications |
| Take-Up (T / UCT) | Slotted housing — sliding adjustment along frame | Conveyor belt tensioning + adjustment |
| Cartridge (C / UCC) | Round insert through bored housing | Custom machine frames with pre-bored housings |
| Hanger (H / UCHA) | Suspended below mounting surface | Overhead shaft support — conveyors, packaging |
| Cast Iron Construction | Heavy + structural strength | Standard industrial — most workshop applications |
| Pressed Steel Construction | Lighter weight + economical | Light-duty + agricultural + farm machinery |
Insert match: Housing accepts a specific bearing insert series — UC200/UC300/UCP200/UCFL200 etc. Match shaft diameter to insert bore (e.g. UCP205 = 25mm shaft). Inserts include their own seal — typically grease-fitted (5,000-10,000 hours service typical). Critical: Take-up housings + slotted-flange housings allow for thermal expansion + assembly tolerance — fixed pillow blocks lock the shaft position. Match housing style to required adjustment. Brands: FYH, NACHI, NSK, Koyo. Companion: all bearings, ball bearings, deep groove bearings, bearing housing guide.
Bearing Housings
Bearing housings mount and protect bearings in industrial machinery, providing a fixed or adjustable mounting point that locates the bearing relative to the shaft and machine frame. They are used across conveyors, fans, pumps, agricultural equipment, and general factory machinery wherever a shaft must be supported at a fixed point on the structure. AIMS Industrial supplies a wide range of bearing housings in cast iron and pressed steel, matched to the major bearing insert series.
Types of Bearing Housings
Bearing housings come in several configurations to suit different shaft orientations and mounting requirements.
- Pillow block (plummer block) housings: Two-bolt or four-bolt base mounting. The most common type — shaft runs parallel to the mounting surface. Suits horizontal shaft applications including conveyor rollers, fans, and pumps.
- Flanged housings: Bolt face-to-face onto a structure or plate. Suited to vertical shafts or where base mounting is not practical. Two, three, and four-bolt flange patterns are available to suit different mounting configurations.
- Take-up housings: Adjustable in the mounting slot to allow belt or chain tension adjustment. Common on conveyor drives and belt-driven machinery where periodic tensioning is required.
- Cartridge housings: Compact, sealed housing for space-constrained applications. Common in agricultural equipment and light to medium industrial machinery.
Cast Iron vs Pressed Steel
Cast iron housings are the industrial standard for most applications — good rigidity, good vibration damping, and long service life under load. Pressed steel housings are lighter and lower cost, suited to agricultural and light-duty industrial applications where cast iron weight is a disadvantage. For heavy-duty, continuous-operation applications, cast iron is the correct choice.
Brands Supplied by AIMS
AIMS Industrial supplies bearing housings from FYH (a premium Japanese manufacturer) and AMI, both widely specified in Australian industry. FYH is the preferred brand at AIMS for quality insert bearing units and matched housings. If you are replacing an existing housing, we can cross-reference from the housing code stamped on the unit to identify the correct replacement.
Matching Housings to Bearing Inserts
Bearing housings and inserts are paired by series — a UC200-series insert fits a UC200-series housing, for example. Always match the bearing insert designation to the correct housing series when ordering. Mixing series causes incorrect fit and premature bearing failure. AIMS can assist with identifying the correct housing for your insert if you have the bearing part number available.
