Spherical roller grease method of choose and buy

Bearing, safe and durable. Self-aligning roller bearing electricity department author on June 29th for your explanation: spherical roller grease method, the choose and buy when using temperature range is a factor we should consider. The use of grease has a certain temperature range, different grease suitable temperature range. The composition of the grease is base oil, thickeners, additives and the use of grease temperature is related to the three components. At low temperatures, spherical roller bearing grease thickened, the hardness increases, the low temperature performance of the grease is directly related to base oil. As well as cooking oil, low temperature liquid temperature will reduce or even stop flow. When reaches a certain temperature, lubricating oil to stop flow, temperature, called pour point ( Pour point) , low pour point of lube oil can be used at low temperature. Mineral oil pour point is in commonly to ℃, but pour point than using a general requirement of low temperature. Low temperature ( Moment) Is an important index of low temperature performance, grease. Under low temperature, the grease will thicken, hardness increased, which hinder the bearing. Low temperature torque is at low temperature (grease C) Stop rolling bearing rotation. The low temperature torque by the starting torque of the grease and operation over a period of time after the torque by means of the average torque. Grease at low temperature, the lower the starting torque, start the power consumption is smaller; On the contrary, if grease at low temperature start, torque. May jam the phenomenon of bearing, in the extremely low temperatures, it is not suitable. Therefore, in the selection of grease temperature, lubrication points ( The highest and the lowest temperature) Must be taken into account, the use of the grease temperature range should include allowing the use of the grease temperature range. Indicators include: associated with temperature drop point, the maximum temperature and minimum temperature, lubricant base oil pour point, low torque and viscosity index base oil. Spherical roller grease method of choose and buy: for some kind of grease, the manufacturer will give a maximum temperature and minimum temperature, the user should remember that when selected, the user needs to consider the highest and lowest temperature lubrication part ( The lowest temperature is usually starts) 。 Bearing comfortable and durable, )
