The steps in the ausformed ball processing are shown figure 3. The heat treatment specifications used for the balls from reference groups I and IT are shown in table I. 4

Tabular Alumina Balls BASF T-162 Tabular Alumina Balls® are sintered alpha alumina with very high-purity. The alumina is form of pure aluminum oxide which has been fired at such high temperatures (well over 1900°C) that practically all porosity and shrinkage is removed. It is essentially 100 percent alpha alumina (corundum).

As the actual inclination angle is beneath 8° (Fig. 4) the tool design is capable to use both deep rolling ball diameters as well as all grinding wheel specifications and feed rates. In a further study at the IFW under similar conditions but an infeed of a e = 0.5 mm, grinding normal forces were determined up to > 600 N .

ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

Consider an ABEC 3 single row, radial ball bearing having 10 balls of 1/16" diameter, 0.330" inner race diameter and 0.452" outer race diameter in a single shield configuration. This means that for a load of P =143 lbs. the rating life of …
