The motor OEM's have a lot of sneaky ways to isolate the core vibration so it doesn't get to the bearing housings where we measure vibration (There might be some benefit in reliability to protecting the bearings from that vib source, but based on conversations with OEM's it's done more to keep the customers from complaining about the 2*LF that shows on their housing vibration measurements).
