The utility model has the advantages that: by adopting the structure, the upper end surface of the upper bearing cover and the lower end surface of the lower bearing cover are arranged in an intersecting manner, and the central axis of the upper bearing cover and the central axis of the lower bearing cover are also arranged in an intersecting manner, so that when the lower bearing cover is vertically placed, the upper bearing cover and the vertical direction keep a certain inclination angle, the axial bearing capacity of the bearing is ensured, the radial (lateral) bearing capacity of the bearing is greatly enhanced, and the integral bearing capacity of the bearing is effectively improved. Meanwhile, the bearing lower cover is provided with a reinforced support structure, so that the bearing capacity of the bearing can be further improved.

The utility model discloses can further set up to strengthen bearing structure and include that the cross-section is the reinforcing ring of L shape, the laminating of the horizontal end of L shape reinforcing ring is fixed and is served radially of bearing lower cover, and the laminating of the vertical end of L shape reinforcing ring is fixed and is served in the axial of bearing lower cover, through setting up strengthening support structure, can show the bearing capacity who improves the bearing lower cover.

The utility model discloses still can further set up to still be provided with sealing device between bearing upper cover and the bearing lower cover, sealing device includes inner seal circle and external seal circle, and inner seal circle and external seal circle set up respectively in the roll body, outside both sides, and inner seal circle and external seal circle all include spacing the spacing collar of fixing on the bearing lower cover, extend on the spacing collar have with the bearing upper cover constitute sealed complex sealing lip limit, still be connected with the radial connection strip between the spacing collar of inner seal circle and the spacing collar of external seal circle, just the radial connection strip inlays to be established in the bearing lower cover, wherein go back the circumference equipartition on the spacing collar of external seal circle and have a plurality of along the post of inserting in the axial embedding bearing lower cover, just the cross-section of post of inserting is the type of calligraphy.

By arranging the sealing device, the sealing performance of the bearing can be effectively improved; meanwhile, the inner sealing ring and the outer sealing ring can be connected into a whole by arranging the radial connecting strip, so that the sealing device is more stable and reliable on the whole; and insert the post through setting up, just the cross-section of inserting the post is type for the better combination of external seal circle and bearing lower cover is in the same place, and further spacing and radial further spacing of radial connecting strip through the axial of inserting the post moreover, make between the internal and external seal circle and with the bearing lower cover between can form firm reliable spacing cooperation, avoid the pine to take off.
