13、 from IHS-,-,-A-A-59626C 3 3.2 Materials. 3.2.1 Rings. The bearing ring material shall be chromium-alloy steel 52100 (UNS G52986) as specified in ASTM International (ASTM) A295/A295M, “Standard Specification for High-Carbon Anti-Friction Bearing Steel“. The finished rings shall not exceed the associ
14、ated billet material inclusion rating also specified in ASTM A295/A295M. Ring hardness shall be at least 58 HRC as defined in ASTM E18, “Standard Test Methods for Rockwell Hardness of Metallic Materials“. The grain size of the ring material shall be determined in accordance with ASTM E112, “Standard
15、 Methods for Determining Average Grain Size“. 3.2.2 Balls. The bearing ball material shall be chromium-alloy steel 52100 (UNS G52986) as specified in ASTM A295/A295M. The finished balls shall not exceed the associated billet material inclusion rating, which is also specified in ASTM A295/A295M. Ball
16、s shall be through-hardened no less than 60 HRC and no more than 67 HRC as defined in ASTM E18. The grain size of the ball material shall be determined in accordance with ASTM E112. 3.2.3 Cage. The bearing cage material shall be impervious to deterioration from any lubricant, preservative, solvent,
17、or other chemical substance expected to contact the bearing during normal use or storage. Similarly, the material shall not cause any chemical deterioration of any other bearing component. Metallic cage materials shall operate from -40 F to 250 F (-40 C to 121 C). Non-metallic cage materials shall o
18、perate from -20 F to 250 F (-30 C to 121 C). Unless otherwise specified in the acquisition order, the cage material shall be one of the optional coded types listed in table II (see 7.3(c).

19、n 6/6 or equal) T Machined non-metallic (phenolic) Y Pressed brass X Other (specify in acquisition order) 1No significant changes from FF-B-171/22. 3.2.4 Shields and seals. Unless otherwise specified in the acquisition order, the shield and seal configuration for the bearing shall be one of the code
20、d options listed in table III (see 7.3(d). The acquisition order shall state which side of the outer ring (heavy shoulder or counterbore side) the shield or seal is to be located (see 7.3(e).

21、 4 TABLE III. Shield and seal configurations. Code 1Configuration option A Open X Other (specify in acquisition order) 1No significant changes from FF-B-171/22. 3.2.4.1 If a single shield or seal is required, the shield or seal material shall be as recommended by the manufacturer, unless otherwise s
22、pecified in the acquisition order (see 7.3(f). The material shall be impervious to deterioration from any lubricant, preservative, solvent, or other chemical substance expected to contact the bearing during normal use or storage. Similarly, the material shall not cause any chemical deterioration of
23、any other bearing component. The shield or seal material shall remain functionally effective at a minimum temperature range of -20 F to 250 F (-30 C to 121 C) for non-metallic and -40 F to 250 F (-40 C to 121 C) for metallic materials. 3.3 Precision tolerance. The bearing precision tolerance level s
24、hall conform to Annular Bearing Engineers Committee (ABEC) class ABEC-1, ABEC-3, ABEC-5, or ABEC-7 as defined in ABMA Standard 20. The tolerance class shall be one of the coded options listed in table IV (see 7.3(g). TABLE IV. Precision tolerance requirements. Code Tolerance class B ABEC-1 F ABEC-3
