What grease recommended when assembling new XR ball screws

What lithium grease is recommended when assembling new XR x and Y ball screws? AI shows NLGI 2. I am unfamiliar with this rating, as I haven’t used lithium for many years. Thanks.

I think that’s just a plain #2 you would find anywhere.

I use lucas white lithium grease its NLGI 2. no complaints so far with it a tubes fairly cheap.

Thanks Jake, picking it up today.
