A bearing seal is suitable for sealing a space between a first rotating body and a second rotating body of a bearing. The first radial end of the bearing seal is arranged on the first rotating body and forms a contact seal with the first rotating body, the second radial end of the bearing seal is arranged close to the second rotating body and forms a non-contact seal with respect to the second rotating body. A plurality of lubricant storage cavities arranged on the inner surface of the bearing seal facing the rolling elements of the bearing. A bearing providing the bearing seal as described above.

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 linear guide with lubrication device includes: a elongate rail; a slide module slidably mounted on the elongate rail and including a slide block and two recirculation members, which are respectively mounted to two end faces of the slide block and include a plurality of recirculation passages, in which at least one of the recirculation members includes a lubricant reservoir and a fixing through hole formed therein such that the lubricant reservoir, the recirculation passage, and the fixing through hole are in communication with each other and the lubricant reservoir receives lubricant filled therein; an application member received in the fixing through hole; a transferring member covering the application member and the transferring member absorbing and transferring lubricant to the application member. Rolling bodies, when moving through the recirculation passage, may contact the application member to have lubricant applied thereto.

The invention relates mainly to a starter (11) for a motor vehicle combustion engine, comprising: an electric motor (15), a drive pinion (60), a pinion body (61) on which said drive pinion (60) is mounted, a drive shaft (12) able to transmit a torque derived from the electric motor (15) to the drive pinion (60) via the pinion body, the pinion body (61) being mounted with the ability to slide axially with respect to the said drive shaft (12), and in which, with there being a chamber (86) delimited notably by one end of the drive shaft (12) and one end of the pinion body (61) opposite the end of the drive shaft (12), the chamber (86) is vented via a through-opening (85) made in an annular wall of the drive shaft (12) or of the pinion body (61).

The bearing provides an outer ring, an inner ring, at least one seal to one of the rings and cooperating with the other ring, and at least one sealing flange. The sealing flange includes a fixing portion to fix the flange to the other ring, an end portion and a connecting portion to connect the fixing portion and end portion. The end portion of the flange is curved and disposed axially facing the connecting portion. The curved end portion and connecting portion define an annular space that open radially towards the other ring. The curved end portion is mounted axially in contact against an outer lateral face of the seal.

Greasable idler pulleys and related kits and methods are disclosed. The greasable idler pulley has a rotating body, a bearing, to enable the rotating body to rotate with respect to a shaft, and grease fitting defined through the rotating body. The rotating body may have a bearing seal cap having an orifice and a rotator. The grease fitting may be in fluid communication with the bearing through the orifice in the bearing seal cap. Kits are also contemplated, such as a kit for retrofitting a non-regreasable idler pulley including a rotator to a regreasable idler pulley. Methods may include methods of producing a regreasable idler pulley from a non-regreasable idler pulley.

A sealing arrangement for a wheel bearing includes a carrier element connectable to a first bearing part of the wheel bearing, a resilient sealing element, and a counterflow plate connectable to a second bearing part of the wheel bearing. The resilient sealing element includes a resilient main body arranged on the carrier element, first and second axial sealing lips extending away from the resilient main body, and a radial sealing lip extending away from the resilient main body. The counterflow plate is arranged with one side facing the carrier element such that the first and second axial sealing lips, and the radial sealing lip, are in sliding contact with the counterflow plate. The first axial sealing lip, second axial sealing lip, and radial sealing lip rest against the counterflow plate with respective contact pressures.

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.
