ZEN TF208-BLACK Flanschlagergehäuse

As a bearing housing, this housing accepts a separately selected bearing insert. All available technical details are listed in the specification table. A housing is half a bearing position: only with the matching insert does it become a bearing arrangement, and not every pairing is permissible. The loads of the insert pass into the structure through the flange face.

The housing bore is machined spherical so the insert’s convex outer ring can align itself as it is tightened; bore form and size must therefore match. Selection is accordingly driven by the bolt pattern, the flange form and the shaft diameter of the intended insert. The seating face of the structure must be flat and stiff enough, because distortion of the bolting plane preloads the bearing position and shortens its life.

Lubrication path and sealing belong to the insert, not to the housing — so for relubrication it is the accessibility of the fitted bearing that matters, not that of the housing. The plastic housing is corrosion-proof and light; it suits wet, chemically loaded or hygienically demanding surroundings at moderate load.
