Increasing use of silicon nitride rollers in recent years has led to the development of ASTM F2094/F2094M, Specification for Silicon Nitride Bearing Balls. It was developed by ASTM Subcommittee F34.01, which is under the jurisdiction of Committee F34 on Rolling Element Bearings./ o) O0 Q* u# Z* X5 G! z
Examples of where hybrid roller bearings are found include high-speed machine tool spindles and high-pressure turbopumps that move liquid hydrogen in a space shuttle. End users of bearings, bearing manufacturers and roller manufacturers will use the standard to procure finished bearings to ensure they're made with sufficient material. Bearing companies can use the new standard to acquire finished silicon nitride rollers from the manufacturers, who will use the standard to ensure that unfinished roller blanks meet the material capability they need. ( J1 k: H7 D! C* j) r& {ASTM F2730/F2730M complements ASTM F2094/F2094M, Specification for Silicon Nitride Bearing Balls, according to William Mandler, general manager of Enceratec Inc. and task group chairman for the group responsible for developing the standard. "ASTM F2730, like ASTM F2094, provides a specification for the material used to make the roller-three levels of capability are included, so the material can be specified for the severity of the intended application," Mandler says. "The specification also provides dimensional specifications for form and surface condition of the finished roller."作者: 伊凡 時間: 2011-6-2 14:40 本帖最后由 伊凡 于 2011-6-2 15:02 編輯 8 T+ s& l4 j% D- ?6 L$ {& ]

建立和完善陶瓷軸承的國家標準，對我們的成產企業非常的重要！9 U8 `! \8 d' V+ b
只有完善相應的標準，才能找到我們和國外的差距，明確目標，才能把握住方向， M0 L9 _6 |" R1 @' {1 u只是苦于我們國家已經沒有一個能夠有說服力的部門來牽頭去做這件事情，一般的企業又沒有這個能力.....
