On June 29, the authors explain for you: self-aligning roller bearing | 22226 bearing grease: the role of anti-friction, sound attenuation, protection, sealing, etc.
Anti-friction grease, should consider the scope of high and low temperature resistance, load and speed, etc. ;
Quieter grease, should consider the adhesion, temperature range, load and speed and so on;
Protective grease, consideration should be given to metal and non-metallic protective and compatibility;
Sealing grease, should consider the compatibility with packing material.
Lubrication part should also according to the product structure and environmental conditions of different to choose grease, self-aligning roller bearings combined basically has the following several indicators: 1.
Working temperature: the minimum working temperature should be higher than that of grease lubrication part low temperature limit, otherwise it will increase the resistance;
The highest temperature should be lower than the temperature of the grease line, otherwise you will lost due to loss of grease lubrication ability;
The highest of the grease suitable temperature should be lower than its drop point 20 ~ 30 ℃.
2.
Speed: the lubrication part of the higher the speed, the greater the shear stress of grease, and part of the high speed regulated temperature rise quickly and easily make grease is thinning and erosion, so should choose grease consistency is bigger.
3.
Bearing load: according to the load selection is one of the keys to ensure lubricating grease, lubricating points should be chosen for heavy load high viscosity of base oil, thickener and high grease;
If is under heavy load and impact load, should choose high extreme pressure and antiwear lubricating grease, such as grease containing molybdenum disulfide.
Self-aligning roller bearing | 22226 bearing grease the role: 1: the conditions of use: environmental conditions refers to the working environment and the surrounding medium lubrication points, such as air humidity, dust and corrosive medium, etc.
In humid environment or under the condition of water contact, can choose the grease of good water resistance.
Such as calcium base, lithium base;
Tough conditions, should be chosen with antirust grease, and unfavorable choose poor water resistance of sodium based fat;
Lubrication points in a strong chemical medium environment, should choose the fluorine element of resistance to chemical medium grease, etc. ;
More dust in the environment, can choose thick grease containing graphite;
To seal have special requirements, should choose sodium base grease.
2: the cost factor: when choosing grease, to consider when using economy, comprehensive analysis using this later whether to extend the grease lubrication cycle, charging times, fat consumption, bearing failure rate and maintenance cost of bearing comfortable and durable,
