1: ntn bearing quenching oil Optional:1. Ordinary quenching oil (oil temperature at 60 ℃ for quenching)Ordinary quenching oil is mainly applied to better hardenability alloy, such as small size bearing steel, mold steel part quenching. The past, only with different grades of domestic mechanical oil as quenching oil. The early 20th century 80, in order to improve the performance of oil cooling, thermal oxidation stability and rust resistance, mechanical oil added to the reminder of cold,

1: ntn bearing deposit:1.ntn bearing the correct storage method is to ntn bearings placed in horizontal position, bearing ring should be supported throughout the side. If the bearing to the location of the vertical display, due to the relatively small thickness of bearing ring,bearing rings and rolling bodies may lead to bearing the weight of the permanent deformation.2. Stockroom of the relative humidity of not more than 60%, little change in temperature,
