Thickened by complex metal soap, SINOPEC Roll Bearing Grease is made from deeply refined mineral oil with extreme pressure additives, rust and oxidation inhibitors through special technical process. According to GB/T 7631.8-90(ISO6743/9-1987), it can be classified as follow:L-XBDEB00,L-XBDEB0,L-XBFEB1,L-XBFEB1-2,L-XBFEB2,L-XBFEB2-3,L-XBFEB3.
Features & Benefits
· Excellent water resistant, anti-rust property. Ensure equipment’s lubrication and protection under condition of exposure to water.
· Excellent high temperature performance. The grease can remain on spot at friction pairs under high temperature. It provide continuous lubricity to bearings and friction pairs so effectively extend service life under high temperature condition.
· Good EP and anti-wear properties. Satisfy lubricating requirements for bearings of heavy load or impact load equipment.
· Excellent oxidation resistant performance. Ensure longer service life during application process.
· Good mechanical stability provide satisfactory consistency even under high speed shear.
· Do not contain any heavy metal, nitrite and other chemical that will do harm to human’s health and pollute environment.
Technical specification
· Meets the following performance specification: Q/SH303 287—2004.
Application
· It is suitable for roll bearings of roughing mill, finishing mill in mini-medium rolling mill and vertical edging mill; it is also used for bearings of light plate mill and plate turnover machine.
· Application temperature range:-20ºC to 180ºC.
