The importance of grease in cast steel bearing seats

Necessity of grease in bearing seats of steel castings

The grease used in bearings must have the practical effect of rust prevention treatment, and the rust prevention oil does not have to dissolve water. The grease should have excellent adhesion and can create a floating oil on the surface of the stainless steel plate, which can be maintained even if the grease is filled with water.

Oil can become loose during the entire process of machining and manufacturing, causing leakage. When there are vibration applications, oil can be thrown from the bearing pedestal into the bearing. If the reliability of the oil mechanical equipment is insufficient, the oil will continue to be thrown out of the bearings, which will cause the soap structured mechanical equipment to collapse and the oil to be destroyed.

It is important to maintain the bearings and lubricants for the skeleton seal. No matter dirt or moisture inside the body, they cannot penetrate the bearings to prevent damage.

Proper installation and maintenance are key elements to fully utilize the long service life of bearings. At the same time, it is important to pay attention to the cleanliness of bearings, the accuracy of bearing selection, and suitable special tools for installation and maintenance. Bearing must avoid environmental pollution caused by pollutants and water, and be properly installed and lubricated. The design scheme of the bearing, the sealing condition of the skeleton, the type of lubricant, the lubrication cycle time, and even the unique maintenance all play a key role.

The water cooled heat dissipating bearing pedestal does not have to be mixed with compatibility related grease. If two incompatible greases are mixed, the consistency of the mortar will generally become loose, and it is likely that the grease will eventually be damaged due to its very easy outflow. If you never know the initial grease application for the bearing, you must first remove the old grease from the inside and outside of the bearing before you can add the grease.

Grease can be classified based on allowable operating temperatures, and the mortar consistency and lubricating ability of water cooled heat dissipating bearing seat grease are affected by operating temperatures. For bearings operating at a certain temperature, it is important to select a grease that has the appropriate mortar consistency and excellent lubrication effect at the same temperature. Grease is produced in different operating temperature ranges and can be divided into ultra-low temperature (LT), medium temperature (MT), and high temperature (HT). At the same time, a grease called EP (anti extrusion molding) or EM is added to improve the compressive strength of the lubricating film.

If you choose unreasonable grease, all countermeasures to avoid bearing damage are self opinionated. Choosing a grease with a base oil viscosity that provides adequate lubrication at operating temperatures is crucial for practical results. Viscosity is critically affected by temperature. It decreases as the temperature increases, and it rises when the temperature decreases. Therefore, it is necessary to understand the viscosity of the base oil at the operating temperature. Machinery and equipment manufacturers generally use certain types of grease, and most standard greases can be widely used.
