Air compressor single row cylindrical roller bearings N, NJ, NU, and NUP can also use full complement or double row cylindrical roller bearings. The high radial load can achieve precise radial guidance with small radial clearance.
Air compressor single row angular contact ball bearings
Mainly used as thrust bearings, installed single or in tandem (in tandem arrangement, they can withstand high thrust loads), suitable for situations where there are both radial loads and high axial loads in one direction, for use in conveying Ammonia medium pumps will also use FP cages (pumps), bearings with a "B" suffix have a contact angle of 40°, such bearings can withstand higher axial loads (pumps), and can also be used with seals bearings.
Newly developed stamped cage double row angular contact ball bearings for overhead compressors with optimized geometric design are mainly used as thrust bearings, mounted individually or in tandem (in tandem configuration they can withstand high thrust loads). Suitable for radial loads and high thrust loads in one direction, also suitable for ammonia pumps with FP cage. Type "B" with a 40° contact angle for higher thrust loads is also suitable for sealing newly developed stamped cages with optimized cage geometry.
Air compressor spherical roller bearings
Can be applied to pumps and can withstand very high pressure, this kind of bearing can compensate for machining defects or misalignment of the shaft, can bear radial and axial loads at the same time, and is suitable for very high loads Self-aligning (up to 2°), dimensionally stable at operating temperatures up to 200°C.
Air compressor tapered roller bearings
It has high axial and radial load carrying capacity, and the bearing has precise radial guiding ability due to the small axial clearance.
Air compressor deep groove ball bearing
It is mainly used for non-locating bearings, and rarely used as fixed bearings. It is suitable for high-speed operation and can also provide a sealed design.
Grease-lubricated deep groove ball bearings are suitable for applications with higher n x dm values, depending on the application, long-life lubrication is also possible, ie without relubrication.
Air compressor four point contact ball bearing
It is mainly used as a thrust bearing in compressors, not to bear radial loads, to bear large axial loads in two directions and to bear small radial loads. Since the inner ring of the four-point contact ball bearing is a split design, this design enables it to accommodate more rolling elements, thereby improving the bearing's radial load capacity.
Because this kind of bearing is a split inner ring design: the machined cage makes them more suitable for high-speed transfer conditions. Due to the small axial clearance, the bearing has precise radial guidance, and the compact bearing design- No separate locating bearing is required.
