Operating limitations of high speed jet lubricated ball bearings [PDF]
A parametric study was performed with 120-mm bore angular-contact ball bearings having a nominal contact angle of 20 degrees. The bearings had either an inner- or an outer-race land riding cage, and lubrication was by recirculating oil jets which had ...

Operating characteristics of 120-millimeter-bore ball bearings at 3 million DN [PDF]
A parametric study was performed with split inner-race 120-mm-bore angular-contact ball bearings at a speed of 25,000 rpm (3 million DN) at initial contact angles of 20 deg and 24 deg.

Bearing tester data compilation, analysis and reporting and bearing math modeling, volume 1 [PDF]
Thermal and mechanical models of high speed angular contact ball bearings operating in LOX and LN2 were developed and verified with limited test data in an effort to further understand the parameters that determine or effect the SSME turbopump bearing ...

Construction of rugged, ultrastable optical assemblies with optical component alignment at the few microradian level [PDF]
A method for constructing quasimonolithic, precision-aligned optical assemblies is presented. Hydroxide-catalysis bonding is used, adapted to allow optimization of component fine alignment prior to the bond setting.

Interference-Fit Life Factors for Ball Bearings [PDF]
The effect of hoop stresses on the rolling-element fatigue life of angular-contact and deep-groove ball bearings was determined for common inner-ring interference fits at the ABEC-5 tolerance level.

Bearing endurance tests in vacuum for sputtered molybdenum disulfide films [PDF]
Angular-contact, 440C stainless steel, ball bearings with sputtered MoS2 films 0.0000006 x 10-7m (6000 A) thick were evaluated in a vacuum bearing chamber (1750 rpm, 137.9-N- (31-lbf-) thrust load) for endurance.

The ball bearing as a rheological test device [PDF]
An angular-contact ball bearing provides an easily obtainable, precise mechanical system for rheological tests on thin films under high pressure. The test conditions are by definition similar to those found in practice.
