    The rolling bearing hungry lubricating materials, lubricants, greases and solid lubricants, and specific lubrication method according to the speed factor dn value.china bearing company

    The rolling bearing lubricant of choice mainly depends on the speed, load, temperature and other working conditions. Under normal circumstances, the viscosity of the lubricant should not be less than 13mm2 / s ~ 32mm2 / s (ball bearing oil viscosity is slightly lower roller bearing is slightly higher). Optional calcium grease grease lubricated bearings in the low-speed, operating temperature below 65 ° c, a higher temperature with sodium base grease and sodium or calcium grease; optional Lithium Grease in the complex high-speed or load conditions; humid environments can be used aluminum grease or barium grease, and should not use the water decomposition of sodium base grease.bearing manufacturer
