NILOS® Steel-Disk Seals Prevent Contamination and Lubricant Leakage

NILOS® steel-disk seals for grease-lubricated roller bearings can provide superior protection against contaminants in mining equipment exposed to extreme levels of dirt, dust, and debris. They can further prevent leakage of lubricant and contribute to optimized bearing service life in a wide range of applications, including idlers, crushers, and conveyor rollers, among others.

Their non-contact, grease-filled labyrinth sealing elements consist of laminated steel-seal disks and steel cores. The seals resist axial pressure and will not slip when clamped in the axial direction of both the inner and outer periphery of a roller-bearing ring.

In use these steel-disk seals offer additional advantages by minimizing bearing friction losses and heat build-up. They are available in a wide range of shaft and casing diameters and are supplied ready-to-install for quick and easy mounting.
Steel-disk seals can be customized to meet application-specific requirements.
