Pumps & Compressors
Pumps are used in all kinds of industries around the world–from petrochemicals and papermaking to irrigation and food processing.
Applications for compressors also vary widely, including factory equipment, air supply equipment for civil engineering and construction projects, HVAC systems for homes and offices, refrigerators, freezers, and more.
NSK bearings support the most critical components in pumps and compressors: their rotating parts. Pumps and compressors must be environmentally friendly, highly reliable, energy-efficient, and low maintenance.
With optimized designs and unparalleled quality, NSK bearings offer long operating life, high load capacity, and high reliability with a focus on the environment and cost savings through reduced energy consumption.
NSK continues to hone its comprehensive strengths in developing next-gen bearings for pumps and compressors that use even less energy with longer life.
Pump and compressor bearings must:
- generate low heat
- have a long operational life
- withstand extreme environmental conditions
- make little noise
- have low vibration characteristics, and more.
NSK aims to serve your needs through our world-renowned design and development strengths, materials and production technologies, and expertise in tribology.
Our ELCOMP Series compressor bearings feature superior oil and chemical resistance, while our double-row angular contact ball bearings and NSKHPS (high-performance standard) angular contact ball bearings help increase pump reliability.
NSK developments make it possible to achieve a longer operational life, greater reliability, and machine downsizing. At NSK, we are proud to provide pumps and compressors with the very latest in bearing technologies.
High Load Capacity Ball Bearings for Screw Compressors
Polyphenylene sulfide (L-PPS) plastic cages provide exceptional chemical stability in bearings specialized for screw compressors.
Features
- L-PPS plastic cages ensure heat resistance and cage strength unaffected by compressor oils, refrigerants, or ammonia gas
- Increased load capacity thanks to an optimized internal design
- Higher axial load limits
- Improved internal lubrication from the ball-guided cage
High Load Capacity Cylindrical Roller Bearings
High-capacity rollers guided by polyphenylene sulfide (L-PPS) plastic cages resistant to chemicals ensure stable operation under high loads.
Features
- L-PPS plastic cages ensure heat resistance and cage strength unaffected by compressor oils, refrigerants, or ammonia gas
- Increased load capacity thanks to an optimized internal design
- Improved internal lubrication from the roller-guided cage.
