Closures are critical components that protect the bearing interior from contaminant ingress. myonic offers a variety of sealing solutions, from basic dust shields to the advanced Filmoseal technology, to meet different application requirements.
myonic Standard Closures - Type "V, Z, X"
The standard shields are stamped from stainless steel and provide non-contact protection. Because the shields do not contact the bearing inner ring, they do not increase the frictional torque, noise development or operating temperature, making them suitable for standard industrial environments. Depending on requirements, the shields can be supplied either permanently mounted or removable.
The standard shields are identified by one of the following letters, all belonging to the same category of non-contact shields:
| Code | Type | Contact Type | Material |
|---|---|---|---|
| V | Standard shield | Non-contact | Stainless steel |
| Z | Standard shield | Non-contact | Stainless steel |
| X | Standard shield | Non-contact | Stainless steel |

Non-Contact Design
A clearance is maintained between the shield and the bearing inner ring, generating no additional friction — suitable for high-speed applications.
Stainless Steel Material
Stamped from stainless steel, corrosion- and wear-resistant, with a service life comparable to that of the bearing.
Flexible Supply
The shields can be supplied either permanently mounted or removable, to accommodate different maintenance requirements.
Filmoseal - myonic Proprietary Capillary Seal Technology (Type "F")
Filmoseal is an innovative sealing technology developed exclusively by myonic, combining the low-friction characteristics of a shield with the high-efficiency protection of a seal. The Filmoseal code letter is "F", marked after the bearing type and before the size specification.

Working Principle
Filmoseal uses the capillary effect to form a continuous oil-film barrier between the shield and the bearing inner ring. This extremely thin oil film can:
- Block external contaminants from entering the bearing interior
- Prevent loss or evaporation of the lubricant
- Maintain the sealing effect without any contact
- Accommodate slight runout and vibration during bearing operation
Filmoseal is particularly suitable for applications involving high-speed operation, or where protection against contamination and resistance to high centrifugal forces is required.
