NKE special coating SQ171E
NKE special coating SQ171E is designed for effective corrosion protection, offering a thinner coating with prolonged resistance. It is suitable for bearings and parts exposed to humid or corrosive environments, providing a cost-effective solution.
Advantages of SQ171E Coating
- Cost-effective protection for standard and special bearings.
- Significantly extends service life compared to uncoated parts.
- Thin coating (2-4 µm) ensures interchangeability with uncoated parts.
- Free from Cr(VI), complying with the RoHS Directive.
Technical Data
- Composition: Zinc alloy.
- Coating thickness: 2 – 4 µm.
- 96 hours of corrosion resistance in salt spray tests (DIN 58979:2008).
- Protection against water, condensation, and weakly acidic/alkaline agents.
- Optional silicate-based seal for enhanced protection.
- Machined surfaces, such as raceways, are also coated.
Applications
- Materials handling (e.g., pulley bearings for cranes).
- Agricultural machinery.
- Chemical and pharmaceutical industries.
- Compressors and pumps.
Comparison with Other Methods
The SQ171E coating offers superior corrosion protection compared to uncoated stainless steel, with a balance of cost-effectiveness and performance.
