A bearing lubrication system includes a bearing assembly comprising a duplex bearing including an outer ring, an inner ring positioned radially inward from the outer ring, and two sets of circumferentially distributed rolling elements between the inner and outer rings. The bearing assembly further includes a housing radially surrounding the duplex bearing and including a lubricant flow passage in fluid communication with a source of lubricant. A flow orifice is located downstream of the lubricant flow passage for jetting the lubricant into the duplex bearing. The flow orifice has an axial location between the two sets of rolling elements.

A gearbox including an angular contact ball bearing comprising a first row of balls provided with a plurality of balls, a second row of balls provided with another plurality of balls, at least one inner ring and at least one outer ring. According to the invention, in a degraded operating mode of the bearing, the first row of balls is configured to transmit at least one first axial force oriented along a first axis and at least one second axial force oriented along a second axis opposite the first axis, the second row of balls transmitting no axial force.

A fixed bearing for a steering gear includes a bearing sleeve, and ball bearing having an inner bearing shell and outer bearing shell. The inner shell is configured to hold a pinion shaft of the steering gear. The outer shell is held in the sleeve. Each shell respectively has at least one guide groove to hold and guide bearing balls, and a pivot ring with an outer ring and inner ring pivotably connected via at least one torsion web. The inner ring is connected to the sleeve. The outer ring is configured to mount the fixed bearing in a steering gear housing. At least one shell is formed from partial shells, each partial shell defining at least a portion of the respective guide groove. The multi-part design enables relatively large guide groove shoulders and a correspondingly relatively high ball bearing load-bearing capacity even under a relatively high tilting load during steering gear operation.

The present invention relates to a chain guide for a bicycle rear derailleur comprising a cage, a guide pulley rotatably mounted to the cage, a circular tension pulley rotatably mounted to the cage, and means for connecting the chain guide to a movable member of a rear derailleur so as to move the chain guide with respect to a bicycle cassette, wherein the guide pulley and the tension pulley are adapted to be engageable with a bicycle chain and wherein the tension pulley is rotatably mounted to the cage by mounting means and an interposed bearing, wherein the mounting means of the tension pulley are arranged so as to be spaced from the center of rotation of the tension pulley and wherein the mounting means are stationary in respect to the cage in the mounted state of the chain guide.

A rolling bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, at least one row of radial rolling elements radially interposed between raceways of the rings, and at least one row of axial rolling elements axially interposed between raceways of the rings. The rolling bearing further provides, axially on each side, at least one row of rolling elements radially interposed between raceways of the first and second rings.

A wheel bearing assembly is disclosed that a bearing ring defining a first splined portion, a joint element including a second splined portion configured to matingly engage with the first splined portion, and a first retention assembly arranged radially outward from the first and second splined portions. The first retention assembly is configured to axially retain the bearing ring with the joint element.

A rotary table bearing 1 includes an outer ring 10, an inner ring 20, and a plurality of rollers 30. The outer ring 10 includes a first body portion 11 and a first steel strip 12. The inner ring 20 includes a second body portion 21 and a second steel strip 22. The first body portion 11 includes a first flange portion 53 of an annular shape that contacts a first end face 31 which is an end face of the roller 30 in the axial direction. The second body portion 21 includes a second flange portion 54 of an annular shape that is located to contact a second end face 32 which is an end face of the roller 30 opposite to the first end face 31 in the axial direction. At least one of an inner circumferential surface of the inner ring 20 and an outer circumferential surface of the outer ring 10 has a gear 114 formed over an entire circumference thereof.
