Assembly, Maintenance and Storage

Transport and Storage

Storage Conditions:

• Constant temperature: +5°C to +40°C
• Relative humidity: maximum 60%
• Avoid direct sunlight
• Recommended monitoring frequency: check 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.
• Chains must never be used, to avoid damaging the surfaces.

Unpacking

myonic bearings are packaged under air-conditioned, cleanest micro-dust room conditions. A clean environment is therefore a basic prerequisite for bearing function and service life. Keep 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 through the rolling elements.

Corrosion Protection: Hand perspiration leads to corrosion. Always wear gloves when handling the bearings.

Assembly Details

Cleaning and Surfaces:

• All adjacent parts must be clean and free of burrs.
• The 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 grease inside the bearing!

Dimensional Check:

• The dimensions and tolerances of the shaft and housing must be verified before starting assembly.

Screw Connection

Fastening screws should be tightened uniformly in a crisscross pattern using a torque wrench, in several steps, to avoid deformation of the rings.

Tightening Sequence

To ensure uniform preload distribution, the 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 the recommended torque values for class 10.9 screws:

Note: The torque values above apply to standard screws of strength class 10.9, with a friction coefficient of approximately μ ≈ 0.12 (lightly oiled). Refer to the specific product specifications for actual applications.

Maintenance

Maintenance mainly concerns relubrication. For detailed information on relubrication, please refer to the Lubrication and Corrosion Protection page.

Measuring Systems

The integrated measuring systems are inductive and are therefore insensitive to magnetism. However, the system must be protected against mechanical shocks to avoid damaging the read head or scale.
