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.

SKF Square 4-Bolt Flanged Units FAQs

Can SKF square 4‑bolt flanged units be used in wash‑down or corrosive environments?

Yes. SKF offers stainless‑steel and hygienic flanged units with corrosion‑resistant housings, stainless inserts and enhanced sealing, designed for food, beverage and other wash‑down applications. Tell us about your cleaning regime and chemicals and we’ll recommend a suitable unit.

Do these units come pre‑lubricated?

Most SKF square 4‑bolt flanged units are supplied pre‑lubricated with grease and ready to install. Many also feature a grease nipple for relubrication during service. We can confirm lubrication details for any specific part number.

What shaft sizes do SKF square 4‑bolt flanged units cover?

SKF square 4‑bolt flanged units are available for a wide range of metric and inch shaft diameters. If you provide your shaft size and whether it is metric or imperial, we can quickly identify the appropriate SKF unit series.
