...Abstract Abstract Occasional failures were experienced in spool-type valves used in a hydraulic system. When a valve would fail, the close-fitting rotary valve would seize, causing loss of flow control of the hydraulic oil. The rotating spool in the valve was made of 8620 steel and was gas...

.... The bearing had not seized, and there was no evidence of heat discoloration in the galled areas. The inner cone, made of modified 4720 steel and carburized for wear resistance, rode on an AISI type 630 (17-4 PH) stainless steel spacer. Consequently, it was desirable to determine whether the galled spots...

... observed on the races in Fig. 15 and 16 . Because of the position of the balls after the slip, bearing rotation became increasingly difficult. It is believed that at this time the bearing seized and spun on the inner housing; this is supported by the evidence of extreme heat exposure observed...

.... A freely rotating bore requires a good lubrication film, or seizing and galling may result. The bore used as a bearing outer race must be as hard as any standard bearing surface and is subject to all conditions of rolling contact, such as fatigue, pitting, spalling, and galling. The bore that is press fit...
