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.
The machine components used in this sector – such as pumps, compressors, electric motors, blowers and ventilators – are particularly susceptible to change. These components contain bearings which have to work reliably and precisely, even in challenging conditions.
Our Application Engineers are in touch with the research and development teams at OEMs and have the expertise to work with you on developing solutions that effectively cut costs and boost productivity.
Pump applications place a great deal of strain on bearings, meaning that the materials used for bearings and bearing cages have to withstand tough conditions.
The bearings have to support axial, radial or combined loads, run equally reliably at low and high speeds (1,500 rpm to 3,000 rpm) and handle different lubrication conditions with ease.

Double Row Angular Contact Ball Bearings
The sealing system of double row angular contact ball bearings prevents the ingress of dirt and ensures an optimum service life. >>
Submersible Pumps
The double-row angular contact ball bearing must withstand axial and radial loads, while the deep groove ball bearing is only subject to light radial loads.
It is important to avoid creep (relative motion) between the outside diameter and housing of the top bearing.
LNG Pumps
Liquefied natural gas (LNG) pumps are used to load/unload cryogenic liquids in tanks.
The bearings used here must be able to withstand a liquid gas temperature of −162°C and are partly lubricated by the pumping medium.
Creep-Free Bearings
Tensioned O-rings mounted in the bearing outer ring improve creep prevention under rotating loads. The product offers easy assemble and the possibility of reusable housings. >>

Roots Blowers
Roots blowers are rotary piston blowers which are often used to transport gas. The gas is carried from the intake side to the exhaust between the lobes of the rotors and the outer wall and compressed by the backflow.
This can generate some vibrations, which bearings must be capable of withstanding.
Oil-Injected and Oil-Free Compressors
Two screws are used to compress gases. The gas enters on the inlet side and flows through the threads while the screws rotate. As the compression space becomes smaller, the gas is compressed.
This process requires bearings that can withstand high radial and axial loads and enable precise shaft positioning.

Conveyor Belts
In the petrochemical industry, conveyor belt systems are often used to transport raw materials.
This places high demands on the bearings’ resistance to factors such as temperatures and contamination.
Ventilators
Ventilators are needed for a wide range of cooling processes.
In most cases, these involve high speeds and temperatures that can reach up to 200°C.
Electric Motors
Electric drives for pumps, compressors, blowers and conveyor belt systems have to withstand high operating temperatures and high speeds.
