Pumps & Compressors

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.
NSKHPS Angular Contact Ball Bearings
Designed for industrial machinery and applications in pumps and compressors: easy handling, long-life, low vibration and quiet running. >>

High Capacity - HR Series
Increased dynamic load rating with larger rolling elements to help improve machinery life performance. >>

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. >>

LNG Pump Bearings
LNG Pump bearings designed to cope with the applications tough operating conditions & extreme temperatures. >>
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.

EW Series Roller Bearings
Features high load carrying capability and high performance pressed steel cage. >>

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. >>

Cylindrical Roller Bearings with Outer Ring guided Brass Cage
Specially designed to meet the tough operating conditions found in oil-free screw compressors. >>
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.

Self-Lube® HLT Inserts
These inserts provide opportunities to reduce maintenance, downtime and replacement costs in operation at extreme temperatures. >>
