SKF FYTBK20 TR Flanschlager-Gehäuseeinheiten

As a housed bearing unit, this product combines a housing with a ready-to-mount bearing insert. The dynamic load rating of 12.7 kN characterises this bearing. The static load rating is 6.55 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 multi-stage seal places several lips in series and is intended for surroundings where dust, moisture and splash water are continuously present. The plastic housing is corrosion-proof and light; it suits wet, chemically loaded or hygienically demanding surroundings at moderate load.
