The drive train includes a first cover mounted to the housing and being configured to seal a rear side of the front bearing, wherein the first cover is mounted to the housing by an auxiliary support which connects the first cover to the housing, a second cover mounted to the housing and being configured to seal a front side of the rear bearing, a third cover mounted to the housing and being configured to seal the rear bearing.

A rolling bearing capable of achieving reduction in torque is provided. The rolling bearing includes an inner ring and an outer ring disposed coaxially with each other, a rolling element disposed between the inner ring and the outer ring, a seal member configured to cover an area between the inner ring and the outer ring from an outside in an axial direction, and filled grease disposed between the rolling element and the seal member. The filled grease includes a first ring-like part which extends to form a circumferential shape centering on a common axis of the inner ring and the outer ring, and which has contact with one of the inner ring and the outer ring, and a second ring-like part which extends to form a circumferential shape centering on the common axis, which is connected to the first ring-like part at an outer side in the axial direction, and which has contact with the seal member.

A deep groove ball bearing includes an outer ring, an inner ring, a cage, and steel balls. The cage is provided between the outer ring and the inner ring. Pockets are formed in the cage, and the steel balls are placed in the pockets. The cage is split into an upper cage body and a lower cage body. Pocket grooves are formed alternately in each of the upper cage body and the lower cage body. A connecting portion is provided between adjacent pocket grooves in the upper cage body. A positioning portion is provided between adjacent pocket grooves in the lower cage body. An insertion piece and an insertion groove are provided between the connecting portion and the positioning portion. The insertion piece and the insertion groove are configured to be fixed with each other to form a fixed connection between the upper cage body and the lower cage body.

A method of manufacturing a slotted entry bearing assembly includes inserting an inner race into a central space of an outer race. The outer race is configured to receive the inner race through at least one slot. Once the inner race is fully inserted into the outer race, it is rotated approximately ninety degrees within the center space, effectively locking the inner race within the outer race. After the inner race is rotated ninety degrees, a molded seal is molded between the inner race and the at least one slot. The molded seal adheres to the at least one slot and is made of a polymeric material. The molding process used to mold the molded seal may be compression molding.

A rolling-element bearing includes a first bearing ring, a second bearing ring, and a seal unit formed in a multiple-piece manner, the seal unit including an at least part-ring shaped main element which is freely rotatable with respect to the first bearing ring and the second bearing ring and at least one seal lip. In addition, the main element and the seal lip are exchangeably connectable to each other.

The disclosure relates to a rolling bearing for a medical or cosmetic instrument having a bearing inner ring revolving around an axis of rotation and a stationary bearing outer ring, which concentrically encloses the bearing inner ring; wherein in the radial direction to the axis of rotation, a bearing gap is formed between the bearing inner ring and the bearing outer ring and a plurality of rolling bodies is arranged in succession in the circumferential direction in the bearing gap, via which the bearing inner ring is mounted in the bearing outer ring; wherein the rolling bodies are arranged rolling on the bearing inner ring and the bearing outer ring and have a rolling body height in the radial direction; and the bearing gap is covered in the axial direction by a cover disk, which is fastened on the bearing outer ring or on a housing accommodating the bearing outer ring or is integrally formed with the housing or the bearing outer ring, and which jointly with the bearing inner ring forms a radial gap extending in the axial direction with a gap length, which gap has a gap height in the radial direction.

The rolling bearing according to the invention disclosure is characterized in that the gap length is at least 25% of the rolling body height.

A bearing, in particular to a self-aligning roller bearing, with a fastener of a sealing disc, which fastener increases the load-bearing strength. The bearing includes a bearing ring with an annular sealing disc which is connected to one of the two bearing ring end surfaces by a fastener which have a shank and a head, which has an enlarged diameter with respect to the shank, and the respective shanks reach through the bores which are made in the respective end surface. Here, the annular surfaces have a cylindrical contour, with the result that the other annular surface provides a raceway, wherein the raceway has a spherical contour, and the bore center axis of each bore in the bearing ring and in the sealing disc has an engaged profile which converges onto the cylindrical contour of the one annular surface.
