NILOS Rings – Metal Seals for Bearings in Harsh Conditions
NILOS Rings stop the damage before it starts. It’s simple, when dust, grit, or slurry get past your seals — your bearing won’t last long. Engineered by Ziller GmbH & Co. KG, these all-metal labyrinth seals are the original solution for keeping contaminants out of rolling bearings.
Godiva Bearings is a UK trade supplier of NILOS Rings — standard and special types — matched to common bearing types and sizes. If your environment eats through rubber, polymer or shielded seals, NILOS offers rugged, zero-nonsense protection with no redesign needed.
They don’t just add protection — they extend uptime. And that makes a difference when the system’s critical.
Why NILOS Rings Are the Industry Standard
- All-metal design stands up to abrasion, impact, and corrosion
- No grease loss, no ingress — just sealed performance
- Available for inner and outer race sealing
- Used with all major bearing brands and types
- Reduces premature bearing failure in harsh environments
These rings work like a metal shield — spinning with the bearing, forming a compact labyrinth seal that keeps out what doesn’t belong.
Where NILOS Rings Perform Best
Mining & Quarrying
Crushers, conveyors and vibrating screens in dusty plants or remote shafts. These rings block silica, coal dust, and fine aggregate particles.
Construction Equipment
Protects wheel-end, boom and pivot bearings on dozers, loaders, mixers and tracked vehicles operating in mud, cement, or gravel.
Agriculture & Forestry
Ideal for harvesters, balers, sprayers and forestry kit exposed to soil, slurry, crop residue, and timber dust.
Pulp, Paper & Woodworking
Stops wood fibres, sawdust and chemical-laden pulp vapour from getting into critical bearing points in continuous or oscillating machinery.
Automotive & Rail
Used in wheel assemblies, couplings, and suspension points exposed to road grit, brake dust and splash.
If your bearings are failing early and you’re replacing too often — this might be your fix.
