15、T NUMBER (E.G., MS14104A-3). REQUIREMENTS: 1. MATERIAL: BALL, 440C (AMS5630, AMS5880, OR AMS5618) OR PH13-8Mo AMS5629 H1000 (SEE NOTE 8 FOR P/N EXAMPLE AND DESIGNATION). RACE, 17-4PH (AMS5643). LINER, PTFE SHALL BE INCLUDED IN THE LINER. 2. SURFACE TEXTURE: BALL DIA Ra 8 MAX; BALL FACES, BALL BORE A
16、ND RACE DIA Ra 32 MAX; ALL OTHER METALLIC SURFACES Ra 125 MAX. LINER SURFACES ARE EXEMPT FROM SURFACE TEXTURE MEASUREMENTS. 3. HARDNESS: BALL, 440C HRC 55-62 OR PH13-8Mo HRC 43 MIN; RACE HRC 28 MIN/HRC 37 MAX BEFORE SWAGING. 4. SURFACE FINISH: RACE: PLATING, WHEN SPECIFIED, SHALL BE ZINC-NICKEL PLAT
17、ING PER AMS2417, TYPE 2, OR CADMIUM PLATING PER AMS-QQ-P-416, TYPE II, CLASS 2, WITH A THICKNESS RANGE OF 0.0003 TO 0.0006 INCHES. PLATE ON THE OUTSIDE DIAMETER SURFACE AND ON THE CHAMFER.
