Nabtesco RV series high-precision gearbox

6.4 Exhaust and Sealing

During installation, it is necessary to exhaust the internal air through the exhaust hole (or oil injection hole) on the housing, otherwise the oil seal may leak due to air resistance. O-ring or sealant (such as Loctite 5699 RTV silicone) should be used to match the end face, and copper containing materials are prohibited (copper will react with lubricant additives).
