What is a square flanged roller bearing unit?
An SKF square flanged roller bearing unit is a ready‑to‑mount assembly that combines:
- A high‑capacity roller bearing
- A square flange housing with four mounting holes
- Seals and lubrication
- A locking arrangement for the shaft
The square flange housing allows the unit to be bolted directly to a machine wall, side panel or bracket, making it ideal for applications where mounting from the side is preferred and space is restricted.
Applications for SKF square flanged roller bearing units
SKF square flanged roller bearing units are used wherever reliable side‑mounted shaft support is required, including:
- Conveyor systems – Side‑mounted shaft supports for rollers, drives and idlers
- Material handling equipment – Elevators, feeders and transfer systems
- Manufacturing machinery – Process lines, packaging machines and handling systems
- Agriculture & food processing – Side‑mounted shafts on conveyors and augers (with appropriate sealing and materials)
- General industrial equipment – Fans, blowers and compact drive arrangements

SKF Square Flanged Roller Bearing Units FAQs
When should I choose a square flanged unit instead of a pillow block?
Choose a square flanged roller bearing unit when the shaft needs to be supported from the side of a machine or panel, or where space is limited and a pillow block (plummer block) cannot be mounted on a base. Square flanges provide a compact, four‑bolt mounting solution that’s ideal for side‑mounted applications.
How do I identify my existing SKF square flanged roller bearing unit?
Look for the SKF part number on the housing or bearing insert. If it’s worn or unreadable, measure the shaft diameter, bolt hole centres and housing dimensions. Provide these details to Acorn and we can help identify a suitable SKF replacement or equivalent.
