NILOS Sealing Rings
NILOS Sealing Rings – Now Available at Bultech
We’ve expanded our product range with another specialized solution that, although not widely known, plays a key role in protecting bearings in heavily contaminated environments.
What are NILOS rings?
These are metal sealing rings mounted onto the inner or outer ring of a bearing to protect it from dust, dirt, and moisture. They are especially effective in high-dust or abrasive environments where standard seals may not be sufficient.

-
Mining industry

Cement factories

Aggregate processing machinery

Specialized engineering applications

Alternatively, simply type Z + the bearing number (e.g. Z2210) in our search bar. We’ve optimized the search function to return compatible options for each bearing.
For example, you may see a result like Z6210 in the image – this is fully compatible with bearings such as Z7210AV, ZNUP210AV, ZNUP2210AV, Z20210AV, Z22210AV, etc.
We’ve listed compatible part numbers under “Catalog Number.” Note: part numbers marked with an asterisk (*) indicate minor dimensional variations – e.g., 1210AV*, 2210AV*, 4210AV*.
