SAE |价值投资网 J22442 (ISO 6149-2) Issued DEC91
—This part of SAE J2244 specifies dimensions, performance requirements, and test procedures for
metric adjustable and nonadjustable heavy-duty (S series) stud ends and O-rings.
Stud ends in accordance with this part of SAE J2244 may be used at working pressures up to 63 MPa for
nonadjustable stud ends and 40 MPa for adjustable stud ends. The permissible working pressure depends
upon materials, design, working conditions, application, etc.
For threaded ports and stud ends for use in new designs in hydraulic fluid power applications, only SAE J2244
shall be used. Threaded ports and stud ends in accordance with ISO 1179, ISO 9974, and SAE J1926 (ISO
11926) shall not be used for new designs in hydraulic fluid power applications.
Conformance to the dimensional information |中国金控集团 in this standard does not guarantee rated performance. Each
manufacturer shall perform testing according to the specification contained in this standard to ensure that
components made to this standard comply with the performance ratings.

现在，卖出去的就是这种炮弹，相比以前的100多毫米的穿深，性能几乎提升了一半以上，完全有能力击穿酋长坦克的正面主装甲，就是因为有了这种穿甲弹，所以，才会有这次69坦克一挑三的光荣战绩。 第六百零八章 不想当将军的士兵 他的心中，已经开始有了无数的波澜了，如果真的能够有一百台发动机的订单，MTU公司开发的这种396柴油机，成本就能全部收回来了，以后就都是净利润了！ “这个，我们当然是支持的，只是，要低息，甚至是无息贷款，这个我也做不了主啊。”高天德说道：“毕竟，银行不是我一个人开的啊。银行的职能，就是通过存款和贷款的利息差来获得收益的，这恐怕有难度啊。” “所以呢？” “走吧，去办公室里谈这些问题。”秦振华笑呵呵地带着几个人，走进了办公室，当关上门的时候，秦振华的脸上的表情，才变得严肃起来：“各位，我们不能把坦克卖给们。” 可以看到，东方大国的市场是很大的，以后还有很大的潜力的！看着MTU公司的生意做的红红火火，而己方的奔驰重卡，反而推广不开，马克思也是相当的恼火，他可是总裁，总裁亲自过来，那是给足了面子的！ 他们的外汇储备是不多，但是，他们的石油数量是相当多的，所以，以货易货的话，就能轻松地解决掉外汇储备不够的问题了。 虽然塞子小，但是，它厚啊！同时外缘角度很大，打中的话跳弹几率相当高，防护性也不错。 米娅已经这么说了，就算是坐实了秦振华的言论了，舒尔茨有些为难地看了看马克思，而马克思的脑子里也在急速地思考着。 既然是自行式的，当然就不能在原地不动，这样也有作弊的嫌疑。 “同时，我任命你为这个项目的负责人，研发资金，从厂里专门的研发资金里面出，你需要的人手，可以向厂里打报告。”秦振华说道：“怎么样，有信心没有？”
