Abstract

A roller bearing outer race of a hydraulic unit having a body having a first part and a second part. The first part comprising a central section having an exterior curved portion, an exterior angled portion, and a circular inner portion, wherein a central aperture defining a first axis passes through the circular inner portion of the central section, a first arm extending from a first side of the central section, and a second arm extending from a second side of the central section. A race within the circular inner portion of the central section, the race defined by a first race wall and a second race wall and wherein a thickness of the first arm and the second arm is about 0.450 inches (1.143 cm) and a radial distance of an exterior surface of the exterior curved portion from the first axis is about 0.657 inches (1.669 cm).

First claim

What is claimed is:

1. A roller bearing outer race of a hydraulic unit, comprising:
a body having a first part and a second part, the first part comprising:
a central section having an exterior curved portion, an exterior angled portion, and a circular inner portion and a central aperture defining a first axis passes through the circular inner portion of the central section;
a first arm extending from a first side of the central section; and
a second arm extending from a second side of the central section; and

a race within the circular inner portion of the central section, the race defined by a first race wall and a second race wall;
wherein a thickness of the first arm and the second arm is about 0.450 inches (1.143 cm) and a radial distance of an exterior surface of the exterior curved portion from the first axis is about 0.657 inches (1.669 cm); and
wherein the second part is attached to the second arm on a side of the second arm opposite the central section and defines a bar extending in a direction perpendicular to the first axis.

2. The roller bearing outer race of claim 1 , wherein the variability of the thickness of the first arm and the second arm is +/−0.010 inches (0.025 cm).

3. The roller bearing outer race of claim 1 , wherein the variability of the radial distance of the exterior surface is +/−0.015 inches (0.038 cm).

4. The roller bearing outer race of claim 1 , wherein the race has an axial thickness, in the direction of the first axis, of about 0.211 inches (0.536 cm) with a variability of about +/−0.003 inches (0.008 cm).

5. The roller bearing outer race of claim 1 , wherein the first race wall has an axial thickness, in the direction of the first axis, of about 0.080 inches (0.203 cm) with a variability of about +/−0.003 inches (0.008 cm).

6. The roller bearing outer race of claim 1 , wherein the diameter of the race is about 1.060 inches (2.692 cm) with a variability of about 0.003 inches (0.008 cm).

7. The roller bearing outer race of claim 1 , wherein at least one of the first arm and the second arm have an aperture extending therethrough with a second axis that is perpendicular to the first axis.

8. The roller bearing outer race of claim 1 , wherein the bar has a thickness in the axial direction of the first axis that is thinner than the thickness of the body.

9. The roller bearing outer race of claim 1 , wherein the bar extends a distance of about 1.438 inches (3.653 cm) with a variability of about +/−0.015 inches (0.038 cm).

10. The roller bearing outer race of claim 1 , wherein the first arm extends a distance of about 1.047 inches (2.659 cm) with a variability of about +/−0.015 inches (0.038 cm) from the first axis.

11. The roller bearing outer race of claim 1 , wherein the second arm extends a distance of about 1.039 inches (2.639 cm) with a variability of about +/−0.015 inches (0.038 cm).
