Advantages
♦ Good demulsifying capability, easy separation of water and oil, protecting bearing, good water adaptability
♦ Good thermal oxidation stability, long service life
♦ Excellent carrying performance, preventing bearing from wear, fewer roller changes
♦ Good filterability, preventing blocking of filter
♦ Good anti-rust, preventing rust of metal parts
♦ Superior anti-foaming performance, ensuring normal oil supply and development of good oil film
♦ Good sealing compatibility, compatible with sealing material of applicable mineral oil
Applications
♦ Suitable for lubrication of oil-film bearings and gears of finishing rolling and pre-finishing rolling of high-speed wire mill, wire mill, plate mill and cold sheet mill
♦ Suitable for lubrication of roughing continuous mill, medium continuous mill and back-up roll bearing of mill
♦ Service temperature range: -5ºC ~120ºC, and 150 ºC for a short time
