  • Application of compound calcium sulfonate grease

    Application of compound calcium sulfonate grease Compound calcium sulfonate grease is a new generation of general-purpose grease, which has almost all the advantages of high temperature grease, but also has the characteristics that other high temperature grease does not have. Especially in water resistance, extreme pressure and shear resistance, it far exceeds other types of grease, making it particularly suitable for steel water rolling, vibration, high temperature

  • What fillers are used in grease

    What are the filler greases, thick grease-like semi-solids. It is used in the friction part of the machine for lubrication and sealing. It is also used on metal surfaces to fill voids and prevent rust. It is mainly composed of mineral oil (or synthetic lubricating oil) and thickener. The main purpose of adding grease to the filler is to improve the lubricity of the grease and enhance the sealing and protection of the grease.

  • Three main factors that lead to high temperature grease loss

    Three main factors that lead to high temperature grease loss High temperature grease generally belongs to synthetic grease and contains high concentration of polytetrafluoroethylene lubricating particles. It has high temperature and pressure resistance and is suitable for high temperature and heavy load equipment. Bearings in high temperature, high load, chemically corrosive environments and components requiring lifetime lubrication, with good chemical inertness, durability and low volatility

  • What are the precautions for storage of grease?

    1. What are the precautions for storage of grease? 1. The package should be well sealed to avoid the intrusion of moisture, dust and oxidative deterioration of grease. 2. When handling and loading and unloading grease, it should be handled as lightly as possible. It is recommended to stand upright to avoid heavy fall and do not roll along the edge of the barrel. 3. Grease should be stored indoors as much as possible to avoid sunlight and rain, no indoor storage for the time being

  • Problems with grease

    Problems with grease use The low temperature performance of grease refers to the ability of the grease to maintain its performance at low temperatures. We know that grease is composed of a base oil plus a thickener and additives. Under low temperature conditions, the thickener of the grease will A certain change has occurred, but it has little effect on the use of grease; and the base oils that make up grease, not only have a large change in viscosity under low temperature conditions

  • Introduction to the correct use of grease

    Introduction to the correct use of grease 1. The amount of grease added should be appropriate. If the amount of grease is too large, the frictional torque will increase, the temperature will increase, and the amount of grease will increase. If the amount of grease is too small, it will not be reliable. Lubrication causes dry friction. In general, the appropriate amount of grease is 1/3 to 1/2 of the total void volume in the bearing. But depending on the situation, sometimes the bearing edge should be greased
