Materials and Manufacture5.1 Before lining, the brass backs shall be bored and thoroughly tinned in accordance with the best standard practice. Afterli

16、ning, the ends of the bearings shall be made smooth by scraping, filing, or machining. They shall not be ground or rubbed withabrasive materials.5.2 The purchaser reserves the right to inspect the brass backs after boring and previous to tinning and lining.5.3 Unless otherwise specified, bearings wi

17、ll be furnished with linings 14 in. (6.35 mm) in thickness.5.4 The bearings shall be sound and free of blowholes, dross, and mechanical defects. All bearing surfaces, including ends,before and after lining, shall be smooth finished and free from sand.6. Chemical Composition of Backing6.1 The backing

18、 metal shall conform to the requirements for named elements shown in Table 1 for Copper Alloy UNS No.C94100.6.2 These specification limits do not preclude the presence of other elements. Limits may be established for unnamed elementsby agreement between manufacturer or supplier and purchaser. Copper

19、 or zinc may be given as remainder and may be taken asthe difference between the sum of all elements analyzed and 100 %. When all named elements in Table 1 are analyzed, their sumshall be 98.7 % minimum.6.3 It is recognized that residual elements may be present in cast copper-base alloys. Analysis s

20、hall be made for residualelements only when specified in the purchase order (Specification B824).6.4 Sampling will be in accordance with the requirements of Practice E255.7.

Examination of Fracture8.1 The finished bearing representing a lot for acceptance shall be broken, either longitudinally or transversely, or both, in orderto ascertain the uniformity of th

25、e grain of the metal. When this fracture shows separation, imperfect mixing of component parts,or dross or dirt spots, the lot shall be rejected.9. Dimensions and Permissible Variations9.1 The purchaser shall furnish drawings showing the dimensions of the bearings ordered and permissible variations

26、therefrom,and the bearings shall conform to these drawings within such permissible variations.9.2 The thickness at the center of the brass and of the complete bearing shall not vary more than 132 in. (0.794 mm) over orunder the normal thickness shown on the drawing. The thickness of the lining shall

27、 not vary more than 132 in. over or under thenormal thickness shown on the drawing.10. Casting Repair10.1 The castings shall not be repair welded.11. Sampling11.1 Bearings shall be divided into lots of 300, or fraction thereof, and one bearing shall be taken from each lot for the purposeof fracture

28、testing and product marking.12. Test Methods12.1 Chemical analysis of the lining shall be made in accordance with Methods E57.13. Product Marking13.1 The name or initials of the manufacturer, the initials of the purchaser, size of journal bearing, pattern number, and year castshall be legibly cast w

29、ith raised figures on a depressed surface of each bearing, as shown on the drawings. When a serial numberis specified, each lot of 300 bearings, or fraction thereof, shall bear the same serial number, commencing with the numeral oneat the beginning of the year and continuing consecutively until the

30、end of the year, at each manufacturers plant.14.
