SKF FYTB20 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. A flanged bearing unit is a complete bearing position: housing, bearing and sealing are matched to one another and bolted to the structure as one assembly.

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