SKF FYK20 TF 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 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. Rings and rolling elements are made of through-hardened standard bearing steel.
