What Are SKF Triangular 3‑Bolt Units?
SKF triangular 3‑bolt units (often called 3‑bolt flange bearing units or 3‑bolt flanged housings) consist of:
- A triangular flanged housing with three equally spaced mounting holes
- A factory-fitted insert bearing, typically self-aligning and sealed
The three-bolt triangular design allows secure, stable mounting onto:
- Machine frames and side plates
- Conveyor structures
- Sheet metal panels and brackets
- Bulkheads and fabricated assemblies
Their slim profile and neat bolt pattern make SKF triangular units a popular choice for OEMs and maintenance teams working with tight layouts.

SKF triangular 3‑bolt units are used in many sectors, including:
- Conveyors and material handling equipment
- Packaging, labelling and printing machinery
- Agricultural and food-processing equipment
- Textile and light manufacturing machinery
- General automation and OEM equipment
They are particularly useful where you need front-face mounting on panels or frames and a compact, secure bolt pattern.
