This topic went round and round on the VAF facebook page, thanks to the OP wanting to use a needle to inject grease into a sealed bearing - when, in fact, it was this type of bearing with an integrated/bonded outer seal.
I think/hope we finally convinced him not to use the injection needle to re-pack his bearings.
