Pumps are used in all kinds of industries around the world:
- chemicals
- papermaking
- irrigation
- foods
Compressors are used for a wide variety of applications:
- factory equipment
- air supply equipment for civil engineering and construction projects
- home and office air conditioning
- refrigerators and cold storage warehouses
This demonstrates just how essential pumps and compressors are to industry. NSK supplies bearings that support the most important mechanism of these pumps and compressors, that of “rotation.” In this way, the company lends support to every field of industry.
Pumps and compressors should:
- be environmentally friendly
- be highly reliable
- consume minimal energy
- have low maintenance costs
Needless to say, NSK aims for the most appropriate designs and enhanced product quality. The company supplies many types of bearings that offer long operating life, high load capacity and high reliability. The goal is low energy consumption for an environmentally friendly approach and low maintenance costs.
Always bearing in mind environmental issues, NSK will continue to concentrate its comprehensive strengths on the development for future generations of pump and compressor bearings that consume even less energy and that have longer working lives.

NSK Experience & Technology
Pump and compressor bearings must:
- generate low heat
- have a long operational life
- withstand extreme environmental conditions
- generate little noise
- have low vibration characteristics, and more.
NSK aims for customer satisfaction in all areas through our world-renowned design and development strengths, materials and production technologies, and expertise in tribology.
To that end, we have developed ELCOMP Series compressor bearings featuring superior oil and chemical resistance, double-row angular contact ball bearings, and NSKHPS (high-performance standard) angular contact ball bearings for increased pump reliability.
These developments make it possible to achieve a longer operational life, greater reliability, and machine downsizing. At NSK, we are proud to provide customers with the very latest in bearing technologies.

A high load capacity bearing for screw compressors that adopts a superiorly chemical-resistant polyphenylene sulphide (L-PPS) plastic cage.
A high load capacity bearing for screw compressors that adopts a superiorly chemical-resistant polyphenylene sulphide (L-PPS) plastic cage.
A high load capacity bearing for screw compressors that adopts a superiorly chemical-resistant polyphenylene sulphide (L-PPS) plastic cage.
Features:
- This bearing adopts an L-PPS plastic cage that features heat-resistant properties in addition to a cage strength that remains unaffected even when exposed to chemicals including compressor oil, refrigerants, or ammonia gas.
- Internal geometry of the bearing has been optimally designed to provide increased load carrying capacity.
- The newly designed internal geometry also increases axial load limits and load capacity.
- The ball guided cage design facilitates improved lubrication of the bearing interior.
