SKF FY1.1/2 TF/VA201 Flanschlager-Gehäuseeinheiten

As a housed bearing unit, this product combines a housing with a ready-to-mount bearing insert. The dynamic load rating of 30.7 kN characterises this bearing. The static load rating is 19 kN. Where a shaft attaches to a vertical wall or machine frame, the flanged form saves the pedestal — it mounts on the face. The unit combines bearing, housing and sealing into a pre-assembled position that is simply bolted down and locked onto the shaft.

The bearing sits with its spherical outer ring in a correspondingly machined housing bore and can align itself as it is tightened, which absorbs misalignment between the two bearing positions of a shaft — the reason this form dominates conveying, agricultural and processing equipment, where mounting is to sheet metal and welded frames. The flange transfers bearing loads into the structure on its face; that seating surface must be flat and stiff enough, because distortion of the bolting plane transfers straight into the bearing.

For design, what matters is the load direction, access for relubrication, and whether one of the shaft’s two positions has to remain axially free. The flinger in front throws off splash water and coarse contamination before it reaches the seal proper — a staged arrangement that markedly extends seal life in heavily contaminated surroundings.

The cast iron housing carries high loads and damps vibration; it is the usual choice for stationary machinery on a fixed foundation.
