【 Jiaxing bearing factory. The performance of the bearing grease and choice

Jiaxing bearing group sales co. , LTD is bearing factory in jiaxing at the center of the province set up a spot directly, inventory sufficient, specializing in HRB bearing brand, service users, professional engineer to solve technical problems for the user, today to introduce about the performance of bearing grease and a matter of choice. In order to ensure the rolling bearing is an effective and reliable operation, it must have sufficient lubrication, in order to prevent the rolling element and raceway and direct metal to metal contact between cage. Lubricant to prevent wear and at the same time protect the bearing surfaces from corrosion. Under different circumstances, therefore, choose the right lubricants and lubrication method, with the correct maintenance is also important. Is suitable for the rolling bearing grease and lubricating oil has a lot of different kinds, and suitable for extremely high temperature solid lubrication of work conditions. The choice of lubricant mainly depends on the bearing working conditions. Let's focus on the introduction of bearing grease, grease is by mineral oil and thickener. Thickener is usually metallic soap, but there are other such as soap polyurea thickener, such as used in the working conditions of high some, such as high working temperature. 1, viscosity of lubricant base oil viscosity in the formation of oil film to separate the bearing inner contact surface, the importance of and its influence on bearing life. In a given bearing grease, its highest speed is depends on the base of the grease oil viscosity. The allowed speed of the grease is also influenced by the shear strength, and shear strength depends on the thickener. 2, grease consistency in accordance with the standards of NLGI set by grease into different level of consistency. Application in bearing grease in its provisions within the temperature range of work after a period of time, the consistency of the grease can't have too big changes. Join because of high temperature grease and become too soft, might leak out beyond bearing. Or because of the low temperature grease and become too hard, and may affect the bearing rotation. 3, the influence of the temperature of grease grease can use temperature range, mainly depends on the base oil, thickener and additive. 4, grease, corrosion resistance and the waterproof performance of grease has certain rust resistance, in order to protect the bearing by corrosion, and should not be outside the configuration when water enters was rushed out of the bearing. The water resistance of the grease is completely depend on the type of thickening agent, compound lithium base, compound calcium base, etc. The rust resistance of the grease is mainly depends on the kind of antirust additive. 5, the compatibility of the grease if you need to convert another grease, we must consider whether the phase, than without adverse effects. If the incompatible mixed together, grease consistency might happen very big change, grease are more likely to be huge loss because of this, the final result in bearing damage. With the same grease base oil, thickener and similar general can mix and there would be no bad reaction.
