Machine Tool Bearings
Made in Germany, ultra-precision rotary bearings
The preferred solution for rotary tables and direct drive systems
myonic Machine Tool Bearings — Synonymous with Ultra-Precision
myonic products are used in rotary table systems, rotary axes, and linear drive units. All bearings are manufactured in fully air-conditioned precision production facilities in Leutkirch, Germany.
From initial sketches to design calculations, prototype manufacturing, assembly, and series production, myonic provides comprehensive technical support. Numerous world-renowned machine tool manufacturers trust in myonic product quality.
Engineering Highlights
myonic continually pushes the boundaries of rotary bearing technology
Cost Optimization / Space Saving
Many applications still use oversized or over-specified bearings. myonic offers cost-optimized alternatives — reducing costs without sacrificing quality while minimizing space requirements and improving rigidity in compact structures like milling heads.
Ultra-Precision Runout Accuracy
When standard catalog accuracy is no longer sufficient, myonic offers significantly tightened radial and axial runout tolerances — providing solutions at the very edge of measurable limits.
High Rigidity Bearing Solutions
When standard bearings cannot meet rigidity requirements, myonic provides custom solutions — such as reinforced inner/outer ring designs or radially preloaded floating bearings to effectively increase rigidity at a single bearing point.
Modular Integration Design
Integrating bearings into surrounding structures for compact, space-saving designs. One or two axial raceways can be integrated into customer structures, protecting proprietary technology while saving costs.
Six Bearing Series
From axial-radial bearings to crossed roller rings, covering all precision rotary application needs
Two-directional, bolt-on, ready-to-install precision bearing unit for high-rigidity applications such as rotary tables or milling heads. Handles axial, radial, and tilting moment loads with zero clearance.
Two-directional, bolt-on precision bearing unit combining high rigidity with high speed, ideal for mill-turn tables or vertical lathes. Handles all-directional loads with zero clearance.
Classic design with optimized friction torque — startup and running torque are nearly identical, fully meeting the demands of modern high-dynamic direct-drive machine axes. Compatible with angle measuring systems.
Two-directional, bolt-on precision bearing with two rows of cylindrical rollers at 45° contact angle in O-arrangement. Rollers are loaded through axial filling slots with uninterrupted raceways for precise, smooth operation. Often used as an alternative to axial-radial bearings for rotary axes.
Consisting of inner and outer rings, cylindrical rollers, and spacers. Rollers are arranged in alternating cross pattern in 90° offset raceways, uniformly absorbing loads and moments from all directions. Provides relatively high axial, radial, and tilting rigidity in an extremely compact form.
Designed for long shafts or high tilting moment applications. Achieves clearance-free operation through radial preload while compensating for length expansion. Can integrate gear mating surfaces, seals, tooth profiles, and other additional functions.
Typical Application Areas
From machine tools to semiconductors, the core of precision rotary systems
Indexing Heads / Rotary Tables
Rotary and swivel tables in 5-axis machining centers, handling heavy cutting torques while maintaining high rotational accuracy and positioning repeatability.
Milling Heads
Swivel axes of universal milling heads, requiring high-rigidity rotation in compact spaces. AXCR crossed roller rings are the preferred choice.
Semiconductor Equipment
Wafer rotation platforms and measurement equipment with zero-clearance ultra-high precision requirements, compatible with angle measuring systems for closed-loop control.
Industrial Robotics / Automation
Robot wrist joints and rotary axes, high-rigidity designs handling compound loads in confined spaces with precise position repeatability.
