scaling of the running surface

scaling of the running surface

The first race surface and the second race surface define a raceway therebetween.

A raceway surface can be protected by low-cost means from early exfoliation caused by hydrogen embrittlement.

Each of the rolling elements rollingly engages the exterior pin surface and the roller interior surface.

A plurality of rolling elements is positioned between the exterior pin surface and the roller interior surface.

The surface of the shaft (5) used as the running surface (12) is arranged between two raceways (10) for rolling elements (14).

Any one of the inner ring raceway surface (2a), the outer ring raceway surface (3a), and the roller rolling surface (4a) of the tapered roller bearing (1) comprises a crowning.

The roll surface is formed to have a finite radius of curvature throughout the potential roll surface.

The center of the oscillation of the bearing race in the reception groove is positioned between the raceway rail-side rolling surface and the slider-side load rolling surface that are opposed to each other.

The area of these portions is substantially larger than the contact area between the rolling elements and the races of the bearing.

In the visual inspection of a tread surface, the area of the wall surface of the partition wall (8) is, preferably, 120% to 400% of the projection area of the tread surface of the tire.

Height in relation to the running surface

Each of the superhard bearing elements (106) may include a bearing surface (112) and a pair of side surfaces (106B) intersecting the bearing surface (112).

The bearing has a first bearing element (20) with a first surface (22) and a second bearing element (30) with a second surface (32).
