摘要： A spherical roller bearing having an outer ring providing at least one inner raceway, an inner ring providing a first and a second outer raceway, a plurality of roller elements arranged in a first and second roller row in-between the at least one inner raceway and the respective first and second outer raceway is provided. The bearing provides a cage for guiding the roller elements in the first and second roller row, the cage includes a plurality of cage pockets, wherein in each cage pocket one of the roller elements is disposed. The bearing further presents a specific pitch circle diameter (PCD), and the cage is essentially in-pitch roller centered in relation to the pitch circle diameter (PCD) when there is an axial force acting on the bearing. In addition, the present invention regards a bearing arrangement and a wind turbine bearing arrangement.

摘要： A roller bearing apparatus including inner and outer rings defining a pair of raceway spaces, a plurality of rollers arranged in oppositely axially inclined rows each occupying one of the raceway spaces, and a guide member. The guide member includes a ring between the roller rows and oppositely extending shortened prongs or stubs extending only a short distance between the rollers so as not to take up space that otherwise could be used for one or more additional rollers. The pocket bottoms are angled to skew the rollers to promote roller precession or indexing. Alternatively, the guide member can include a reduced number of larger prongs to replace one or more of the stubs.

摘要： A rotatable seal cage assembly for positioning between relatively movable members including a ring with inner and outer circumferential edges, which edges are joined by two flat side surfaces extending therebetween. An annular projecting surface extends from one of the ring side surfaces. A projection extends from the other side surface of the ring to be engaged by rotatable bearings to rotate the ring when relative rotation of the members occurs. Radially spaced seals are provided on each side of the annular projecting surface to seal between the rotatable seal cage assembly and each of the relatively movable members and inhibit damage to the radially spaced seals between the relatively movable members.

摘要： The bearing capacity of a rotary rock bit is increased by providing a bearing separator and sealing system which maintains the cylindrical roller bearings in proper alignment without interfering with the integrity of the seal. A spacer unit is positioned around the bearing pin of the rock bit between the cutter member and the bearing pin. The spacer unit includes an annular body with a plurality of separator elements cantilevered from said annular body extending toward the outer end of the bearing pin. The cylindrical rollers are alternately positioned between the separator elements. The annular body of the spacer unit is located in the cone mouth of the cutter member. A seal member is located in the cone mouth of the cutter member between the rock bit body and the annular body of the spacer unit.
