Transport and Storage
Storage Conditions:
- Constant temperature: +5°C to +40°C
- Relative humidity: maximum 60%
- Avoid direct sunlight
- Recommended monitoring frequency: every 2 hours (for sensitive environments)
Handling:
- Large bearings must be stored and transported horizontally (lying flat).
- For heavy units, use eyebolts or textile straps for lifting.
- Never use chains to avoid surface damage.
Unpacking
myonic bearings are packaged under air-conditioned and cleanest micro-dust room conditions. Clean environmental conditions are therefore a basic prerequisite for bearing function and service life.
Please retain the original packaging until immediately before installation. Paired bearing sets must not be separated or mixed with other sets. Installation forces must never be transmitted via the rolling elements.
Corrosion Protection: Hand perspiration leads to corrosion. Always wear gloves when handling bearings.
Assembly Details
Cleaning and Surface:
- All adjacent parts must be clean and burr-free.
- Surface roughness of adjacent parts should be a maximum of 0.8 Ra.
- Only the outer surfaces of the bearing may be cleaned using lint-free cloths and organic cleaners or warm cleaning oil.
- Never wash out the lubricant inside the bearing!
Dimensional Verification:
- Shaft and housing dimensions and tolerances must be verified before starting installation.
Screw Connection
Fastening screws should be tightened evenly in a crisscross pattern using a torque wrench, in several steps to avoid ring deformation.
Tightening Sequence
To ensure uniform preload distribution, screws must be tightened in a specific crisscross sequence. The diagram below shows a typical tightening sequence:
Torque Values for Class 10.9 Screws
The following table lists recommended torque values for class 10.9 screws:
| Thread Size | M3 | M4 | M5 | M6 | M8 | M10 | M12 | M14 | M16 | M20 |
|---|---|---|---|---|---|---|---|---|---|---|
| Torque (Nm) | 1.4 | 3.3 | 6.5 | 11 | 27 | 54 | 93 | 148 | 230 | 450 |
Note: The above torque values apply to standard screws of strength class 10.9, friction coefficient approximately 0.12 (lightly oiled). Please refer to specific product specifications for actual applications.
Maintenance
Maintenance mainly relates to relubrication. For detailed information on relubrication, please refer to the Lubrication and Preservatives page.
Measuring Systems
Integrated measuring systems are inductive and therefore not magnetically sensitive. However, the system must be protected against mechanical shocks to avoid damage to the read head or scale.
