conditions: environmental conditions refer to the work environment and the surrounding medium lubrication points, such as air humidity, dust and corrosive medium. In contact with water or damp environment condition, can choose the grease of water resistance. Such as calcium, lithium base; harsh conditions, should be used with grease and rust, but should not use sodium base grease water resistance is poor; ferris wheel bearing in the lubrication points with strong chemical medium environment, should be chemical resistant selection of fluorine element grease; in the environment with more dust, grease containing graphite thick optional; to seal with special requirements, should use sodium base grease.
5 cost factors: in the selection of grease, but also consider the economic use, comprehensive analysis using this grease is extending the lubrication cycle, charging times, fat consumption, bearing failure rate and repair cost.
Use the matters needing attention
Rolling bearings Slewing drives make precision parts, and therefore requested the use of the corresponding support cautious attitude, not only changing bearing high performance, if used improperly, can not achieve the expected performance, so, use of the bearing that should pay attention to the following items:
Keep the bearings and the surrounding environment clean. Even the eyes can not see the smile dirt into the bearing, also increase the bearing wear, vibration and noise.
Use the installation carefully, do not allow powerful punch, bearing does not allow direct percussion bearing with a hammer, not allowed to pass through the rolling pressure.
Use tools appropriate, accurate, as far as possible the use of special tools, the use of fabric and fiber or something to avoid.
