What oil to use for lubricating control system bearings and components.

Checked my Ventus maintenance manual:
"The Ventus" should be lubricated with acid free grease and oil customary in trade"
"ball bearing with sealed grease filling do not require service"-are these the bearing with a felt enclosure

Bearings with a felt covering are definitely not sealed, nor even shielded. On my
Schleicher gliders, I stick the straw (one a can of LPS2) underneath the felt and
give the bearing a show every few years.
