In March 2020, in-line bushings of 2-276900 in a quantity of 10 pieces were manufactured and shipped to PJSC DNIPROSPEZSTAHL-BAG.
The liner of the fluid friction bearing of the rolling roll support has an inner surface with two oil supply pockets, which is elliptical, with the major axis of the ellipse parallel to the oil supply pockets.
The insert sleeve, like the pin sleeve, is the main part of the fluid friction bearing (hydrodynamic support of the rolling roll), designed to absorb radial load.
The insert bush is a thin-walled cylinder with a collar or other element with which it is fixed in the bearing pillow. To supply lubrication to the friction zone, the inner surface of the liner is equipped with oil pockets.
