The insert element may be configured to guide a rolling element retained in the bearing cage and/or be configured as a lubricant reservoir.

In a tapered roller bearing, a large-diameter-side annular portion includes large-diameter-side pocket surfaces opposed to the large end surfaces of the respective tapered rollers; and oil retaining recesses each having an opening spanning the inner peripheral surface of the large-diameter-side annular portion and each of the large-diameter-side pocket surfaces. Each oil retaining recess has an inner surface having a radially inwardly facing surface portion, the radially inwardly facing portion being an inclined surface radially inwardly inclined toward the corresponding tapered roller.

The present disclosure regards 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 disposed between the at least one inner raceway and the respective first and second outer raceway, the roller elements further providing axially inner ends. Moreover, the bearing includes a cage for one of guiding and retaining the roller elements in the first and second roller row, the cage including a plurality of cage pockets, wherein one of the roller elements is disposed within each cage pocket, and wherein the cage is roller centered by the axially inner ends.

A roller retainer cage for a roller thrust bearing, including a first cage half with an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, a second cage half including an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, wherein the first flange of the first cage half is disposed radially-outwardly of the first flange of the second cage half, the second flange of the first cage half is disposed radially-inwardly of the second flange of the second cage half, and the first cage half is comprised of a through-hardened metal.

A bearing cage is disclosed that includes a first ring and a second ring with a plurality of crossbars extending therebetween to define a plurality of rolling element pockets. The first ring and the second ring each include a plurality of radially outward protrusions, a plurality of reliefs, and a plurality of axially extending protrusions extending into the plurality of rolling element pockets. The plurality of crossbars each include a plurality of retention tabs configured to engage rolling elements in the plurality of rolling element pockets.

A roller retainer cage for a roller thrust bearing, including a first cage half with an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, a second cage half including an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, wherein the first flange of the first cage half is disposed radially-outwardly of the first flange of the second cage half, the second flange of the first cage half is disposed radially-inwardly of the second flange of the second cage half, and the first cage half is comprised of a through-hardened metal.

The present invention relates to a joint assembly for a driveshaft comprising, a yoke stub (1) with multiple channels (3) in the direction of extension; a tube sleeve (2) is having a recess (4) aligned corresponding channel (3) and telescopically engaged with a yoke stub (1). The driveshaft further comprises multiple rollers (14) spaced apart from each other in such a way that providing axial movement between the channel (3) and the corresponding recess (4) to transmit torque and a cage (12) extending between the rollers (14) to secure them together.

A roller retainer cage for a roller thrust bearing, including a first cage half with an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, a second cage half including an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, wherein the first flange of the first cage half is disposed radially-outwardly of the first flange of the second cage half, the second flange of the first cage half is disposed radially-inwardly of the second flange of the second cage half, and the first cage half is comprised of a through-hardened metal.

A rolling-element bearing cage includes a plurality of pockets each configured to receive a rolling element, and retaining elements associated with each of the plurality of pockets, each of the retaining elements being configured to secure the rolling elements against falling out of the pockets in a radially inward direction while permitting the rolling elements to be inserted into the pockets in a radially outward direction.
