Material hardness shall be no less than Rockwell hardness number of 58 on Rockwell C scale (HRC) and no more than 6
20、4 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 use or st
21、orage. 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 conform to
22、 tolerance class 4 as tabulated in ABMA Standard 19.2. Allowable tolerances for bearing components and assembled bearings are listed in tables II through VI. TABLE II. Cone bore tolerance.

26、c load rating. 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 requirements specified in ABMA Standard 11, “Load Ratings and Fatigue Life for Roller Bearings“. 3.5 Effective load center. Dimension (a
27、) in figure 1 locates a point on the cone axis, which is the center of pressure of all resisting forces set up by the rollers. All moments should be calculated from this point when determining bearing loading and shaft stresses. A plus value of (a) indicates that the center is outside the cone backf

The bearings shall be furnished without lubrication. 3.7 Steep angle. A steep angle bearing has a contact angle between 22 and 31 degrees. The contact angle is the ang
29、le between the line of action of the roller load and a plane perpendicular to the bearing axis. 4. REGULATORY REQUIREMENTS 4.1 Recovered materials. The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Ac
30、quisition Regulation (FAR). 4.2 Foreign acquisition restrictions.
