Typical Applications
SKF square 4‑bolt flanged units are widely used wherever a shaft end or intermediate shaft needs to be supported on a flat surface, including:
- Conveyor head and tail pulleys
- Fans, blowers and ventilation systems
- Agricultural and food processing machinery
- Packaging, bottling and handling equipment
- Textile and printing machinery
- General industrial and OEM machinery
Their four‑bolt square footprint provides secure, rigid support for rotating shafts in both horizontal and vertical mounting positions.
What Are SKF Square 4‑Bolt Flanged Units?
SKF square 4‑bolt flanged units are complete mounted bearing assemblies that typically include:
- A self‑aligning insert bearing (often a deep groove ball bearing type)
- A square 4‑bolt flanged housing
- Integrated seals
- A locking device to secure the bearing on the shaft
The housing is bolted to a side wall, plate or machine frame, with the shaft passing through the bearing bore at 90° to the mounting surface. Because bearing and housing are matched and pre‑assembled by SKF, these units provide a reliable, easy‑to‑install solution with minimal engineering effort.
