Bearings

Always bearing good ideas in mind

Being unseen components in the overall structure of a technical product, bearings often go under appreciated. Their crucial importance can’t be stressed enough, though, as they guarantee the smooth execution of a process – whether it’s measuring, metering or moving. Bearings from OSKAR MOSER are known for their precision and long service life. Having produced millions of reliable sapphire bearings for electricity meters, OSKAR MOSER have established an international reputation and a high profile.

Our bearings are used in many different applications today, from machine building to medical technology to measuring devices for the energy of the future: green hydrogen.

Fixed bearings

Fixed bearings are subjected to both movement and loads. This image shows a CAD visualisation of a new fixed bearing with high-quality components from OSKAR MOSER. A fixed bearing is a bearing which can accept both radial and axial forces. It fixes the position of the shaft or component in the axial direction, preventing movement along the axis.

Our fixed bearings are used in a host of different applications, including:

Machine building (shaft and axis bearings)
Precision mechanics (precision instruments like clocks and measuring devices)

Floating bearings / air nozzles

Floating bearings serve the purpose of accepting radial forces. They’re often used in machines and systems to enable rotational movements while still ensuring high stability. Areas of use include motors, pumps, fans, compressors, generators and other rotating machines.

Air bearings and air nozzles are machine elements – they separate two sub-components which move against one another with a thin film of air, thereby guaranteeing nearly frictionless movement. A differentiation is made between dynamic bearings, which create a cushion of air through the movement itself, and static bearings, where compressed air is fed in. These types of systems are used in precision machines, such as measuring machines (measuring devices, gas meters, LFEs and mass flow meters), processing machines and in aerospace & medical technology.

Bearing screws

Bearing screws with rubies or sapphires are special screws which secure jewel bearings (usually synthetic rubies or sapphires) in mechanical clock mechanisms or precision instruments. Bearing screws ensure the stable and secure attachment of the jewel bearings and reduce friction and wear in moving components.

Their advantages include:

Minimal friction
High wear resistance
Resistance to corrosion
An increase in the service life of mechanical systems

Areas of use include:

The clock industry, precision mechanics and measuring technology (theodolites, micrometers and scales)
Optical devices (microscopes, telescopes and other optical devices)
Aerospace (high-precision instruments, sensors and gyroscopic systems)
