Our Core Expertise
NILOS Rings (Types AV & JV)
Contact seals that form fine labyrinth grooves during run-in. These extend bearing life by keeping grease in and contaminants out type AV seals the outer ring; JV seals the inner ring.Specialized Variants (ZAV, ZJV, AK, LSTO & LST-L)
ZAV/ZJV seal bearings already equipped with shields
AK provides double sealing for tapered bearings
LSTO and LST-L disk seals deliver non-contact protection in high-dirt or liquid-exposed environments
German Engineering & Durability
All-metal seals crafted from galvanized steel (with stainless or brass upon request), accommodating speeds up to 6 m/s (standard), up to 30 m/s for LSTO, and up to 3 m/s in liquid environments for LST‑L types.Space Efficiency & Easy Integration
Low-profile design that fits into minimal axial space (installation height = h + 1 mm). Ideal for retrofitting into existing systems .
Why NILOS Technology Matters
Minimal Wear, Maximum Life
Labyrinth grooves reduce friction after initial run-in, safeguarding bearings with negligible maintenance .Versatility Across Applications
Effective in mining, construction, agriculture, electric motors, power tools, and automotive – in virtually any bearing assembly.Built for Industrial Environments
Durable in high-speed, high-dirt, or fluid-exposed settings; special types with grease chambers or Viton seals add extra protection
About the Product Range
