Machine tool bearings

myonic can also do big!

myonic products are used in rotary table systems and rotary axes as well as in linear drive units.
myonic bearings are manufactured exclusively in Germany. Only ultra-precision machine tools are used in our fully air-conditioned production facility.

Combined with modern processes, rolling element bearings of the highest quality are produced.
Our development engineers and test benches are located in the immediate vicinity of production. Short distances increase flexibility and the speed required to quickly implement perfect solutions for our customers.

Innovations & Concepts

Cost-optimised bearing solutions

Increasing cost pressure requires a consistent review of all potential savings.

In many applications, bearing solutions are still used that are oversized or are not required in terms of their accuracy.

myonic offers cost-optimised alternatives – without compromising on production quality or process reliability.

Ultra-restricted Running accuracies

myonic bearings stand for the highest quality and precision.

The dimensional and running accuracies correspond to the known catalogue values and can be restricted further if required.

For applications in which even this accuracy is not sufficient, myonic offers the option of specifying significantly tighter radial and axial run-out tolerances. run-out tolerances.

If your requirements go to the limits of what is technically feasible, we deliver solutions with red If your requirements go to the limits of what is technically feasible, we deliver solutions with tolerances on the edge of what can be measured – for maximum precision without compromise. on the edge of what can be measucompromise.

Bearings for increased rigidity requirements

If the requirements for rigidity are not met by standard bearings…

…on the market, myonic offers customised solutions that meet the highest
demands.

For example, a bearing with a reinforced inner and outer ring can be used to increase rigidity at just one bearing point.

Alternatively, our radially preloaded, bolt-on floating bearing is a simple and highly effective solution for increasing rigidity.

Modular integration into the design

The integration of the bearing into the surrounding structure offers many advantages.

In addition to a compact, spacesaving design, costs can also be saved by eliminating unnecessary components. The solution from myonic for integrating your components into the bearing system provides the ideal modular system for this.

You have the freedom to integrate one or both axial raceways into your design – or to use the bearing purely as a radial non-locating bearing. This allows you to protect your expertise and save installation space and costs at the same time.

Space-saving
solutions

Installation space is a valuable commodity – especially in compact designs such as milling heads.

It is therefore crucial to minimise interference contours and make optimum use of the available installation space.
With our new bearing concept, we offer maximum rigidity with reduced space requirements.

Where previously lower-performance bearing solutions were used, the myonic concept significantly increases rigidity – without taking up additional
installation space.

Axial-radial bearings / Rotary table bearing

AXRY-NGX

Next-Generation Axial-Radial Bearings, maximum rigidity

AXRY-NGX bearings are double direction, screw-on precision bearing units ready for installation and intended for highly rigid applications, for example for rotary tables or milling heads.

The bearing absorbs axial and radial forces and tilting moments backlash-free.

AXRY NGX bearings offer optimum speed, rigidity and life time in the available space. The bearings are greased as standard with a special grease according to DIN 51825-KPH-C1N-30.

Other greases or ungreased bearings are available on request.

AXRY-NGS

Next-Generation Axial-Radial Bearings, maximum speed

AXRY-NGS bearings are double-direction, screw-on precision bearing units ready for installation and intended for highly rigid and at the same time high-speed applications, for example for Mill-turn tables or vertical lathes.

AXRY-EX

Axial-Radial Bearings for rigid applications

myonic AXRY-EX axial-radial bearings are double-direction, screw-on precision bearing units ready for installation and intended for rigid applications, for example for rotary tables or milling heads.
The bearing absorbs axial and radial forces on both sides as well as tilting moments backlash-free. AXRY-EX bearings are suitable for lifetime grease lubrication, and are designed for maximum rigidity.

The friction torques of the bearing have been optimised, and the starting torque and running torque are almost identical.
In this way, myonic-AXRY-EX bearings fulfil all the requirements for modern highly dynamic and direct-driven machine axes. AXRY-EX bearings will be replaced by the new generation AXRY-NGX in the future. For high speed applications we recommend AXRY-NGS bearings.

Accuracy / designs

For the EX bearings, all variations, such as limitation of the axial and radial runout, height tolerances H1/H2 and the design with supported L-section ring AC are available without limitations.

Measuring system

AXRY-EX bearings can be equipped with inductive angle measurement systems. These are available in incremental and absolute design (as single or multi-head systems in very different accuracies). Mounting this system onto the bearing facilitates maximum accuracies through the exploitation of the precision on the bearing ring with minimal concentricity errors to the shaft (table). See more in the chapter Measuring systems.

Axial-Radial Bearings with angle measuring systems

AXRY bearings can be equipped with inductive angle measuring systems. These are available in incremental or absolute versions, as single or multi-head systems in various accuracies.

By mounting the measuring ring directly on the bearing ring, concentricity errors with respect to the shaft (table) are minimised and thus highest accuracies of a few angular seconds are realised.

myonic only supplies the “mechanical part”, i.e. the bearing including the mounted measuring ring and thread in the outer ring for axial or radial scanning head mounting.

Angular contact roller bearing

AXDR

Double row angular contact roller bearings

AXDR Double row angular contact roller bearings are double-direction, screw-on precision bearing units ready for installation for applications with high rigidity requirements such as rotary tables or milling heads.

The bearing absorbs both axial and radial torques and tilting moments backlash-free.
AXDR bearings feature two raceways with tilted cylindrical rollers laid out in an O-arrangement. The pressure angle of 45° is ideal in order to absorb all the forces occurring in machine tools.

Bearing structure

AXDR bearings consist of 2 rings:
■ Inner ring
■ Outer ring
The rollers are introduced via special axial filling openings in the bearing; these are sealed with a plug.
In contrast to radial filling holes, the raceway is not interrupted. This leads to accurate and smooth running of the bearings.
AXDR are filled with full complement (bearing type VX).

Applications

Due to the high design strength,
AXDR bearings are not sensitive to the surrounding construction; the bearings can be installed more easily.
AXDR Double row angular contact roller bearings are frequently used as an alternative to axial-radial bearings in rotary axes and swivel axes.

Cross roller bearings

AXCR

Cross roller bearings for compact bearing types

AXCR cross roller bearings consist of an inner and outer ring, cylindrical rollers and spacers. Due to their compact size, these bearing types are frequently used as swivel bearings.

Typical applications are milling heads, swivel axes or robots, but also industrial applications with increased accuracy requirements.
In cross roller bearings, the cylindrical rollers are arranged cross-wise in a raceway offset by 90° so that loads and torques can be evenly absorbed in all directions.
Cross roller bearings offer relatively high axial and radial rigidities and tilting rigidity in highly compact constructions.

Special bearings

XC

Floating bearings and special bearings

For long axes or axes with high applications of pressure through tilting moments, a counter bearing can substantially increase the performance capacity.

The bearings are preloaded via the radial part and therefore run backlash-free, but can balance out length expansions.

Integration

Further functions can be integrated into these bearing types:
■ Fit seats for additional parts such as toothed wheels or measuring flanges
■ Counter faces for shaft sealing rings
■ Seals
■ Toothings
