Announcement of torque transmission change on stainless coupling, “XBWS”・“XBSS”

We deeply thank you for your using NBK website.
We would like to announce that torque transmission on stainless coupling, “XBWS”・“XBSS” will be changed. NBK employs high strength stainless bolt “YUS-550” for assembling.
However, this bolt will be no longer in production. Hence, we are afraid but we have no choice to switch assembly bolt from “YUS-550” to “SUS-XM7”. As a result, it will cause to change tensile strength rank and coupling transmission torque. Moreover, Part No. Will be amended due to the change of coupling mechanical property.

We are sorry for any inconvenience this may cause you and appreciate your cooperation and understanding.
