What kinds of air compressor bearings are there?
Air compressor single row cylindrical roller bearing n,? NJ，？ Anger? And then what? NUP can also use full roller or double-row cylindrical roller bearings with high radial load and small radial clearance to obtain accurate radial guidance.
Characteristics of air compressor bearings
Single row angular contact ball bearing for air compressor
Mainly used as thrust bearing, single installation or series installation? (series arrangement, can bear high thrust load), suitable for both radial load and high axial load in one direction. The pump for transporting ammonia medium will also adopt FP cage (pump), and the bearing with suffix "B" has a contact angle of 40, so that the bearing can bear higher axial load (pump) or a sealed bearing can be adopted. The newly developed double-row angular contact ball bearings with optimized geometric design for air compressor with stamping cage are mainly used as thrust bearings, which are installed separately or in series (series structure can bear high thrust load). Suitable for radial load and high thrust load in one direction, and also suitable for ammonia pump with FP cage. The model "B" with 40 contact angle can bear higher thrust load and is also suitable for sealing the newly developed stamping cage, and the geometry of the cage is optimized.
Self-aligning roller bearing of air compressor
Can be applied to pumps and can withstand high pressure. This kind of bearing can compensate the machining defects or misalignment of the shaft, and can bear both radial load and axial load, which is suitable for self-aligning under high load (up to? 2) Maintain dimensional stability at working temperature up to 200℃
Tapered roller bearing of air compressor
It has high axial and radial bearing capacity, and because of the small axial clearance, the bearing has accurate radial guiding ability. Mainly used for floating end bearings, rarely used as fixed end bearings, suitable for high-speed operation, and can also provide sealing design. Grease lubricated deep groove ball bearings are suitable for high N? x？ In the case of dm value, depending on the specific application, long-life lubrication is also possible, that is, lubrication is not needed.
Air compressor four-point contact ball bearing?
It is mainly used as a thrust bearing in the compressor, instead of bearing radial load, bearing larger axial load in two directions and bearing smaller radial load. Because the inner ring of the four-point contact ball bearing is a split design, this design can accommodate more rolling bodies, thus improving the radial bearing capacity of the bearing. Because these bearings are designed with split inner rings, machined cages make them more suitable for high-speed transportation. Because of the small axial clearance, the bearing has accurate radial guiding ability, and the compact bearing design does not need a separate positioning bearing.
Bearing is a very important part for air compressor. The quality of bearing directly affects the life of air compressor, so the selection of bearing for air compressor is very important. When choosing bearings, you must choose genuine bearings produced by regular manufacturers, and don't buy fake pumps for cheap. Due to the limitation of production cost and technology, counterfeit bearings are immature in many aspects and poor in quality. If this kind of bearing is used in air compressor, it will affect the service life of air compressor.
