Material hardness shall be no less than Rockwell hardness number of 58 on Rockwell C scale (HRC) and no m

20、ore than 64 HRC as defined in ASTM E18, “Standard Test Methods for Rockwell Hardness of Metallic Materials“. 3.2.2 Cage. The bearing cage material shall be impervious to deterioration from any lubricant, preservative, solvent, or other chemical substance expected to contact the bearing during normal

21、 use or storage. Similarly, the material shall not cause any chemical deterioration of any other bearing component. The cages shall be made from carbon steel (one piece stamped). Materials shall operate from -65 to 230 F (-53.9 to 110 C). 3.3 Tolerance class. The tolerance limits for bearings shall

22、conform to tolerance class 4 as tabulated in ABMA Standard 19.2. Allowable tolerances for bearing components and assembled bearings are listed in tables II through V. TABLE II.

The bearing dynamic load rating shall conform to the requirements specified in table I for each bearing size code. The listed ratings conform to the

26、 requirements specified in ABMA Standard 11, “Load Ratings and Fatigue Life for Roller Bearings“. 3.5 Lubrication. The bearings shall be furnished without lubrication. 3.6 Contact angle. All bearings are normal angle bearings having a contact angle between 10 and 19 degrees. The contact angle is the

27、 angle between the line of action of the roller load and a plane perpendicular to the bearing axis.
