NILOSRING 25X55X3 33205 AK NILOS

Product description:

• Nilos rings provide a simple, low-cost and space-saving seal for grease-lubricated non-setting bearings, particularly groove ball bearings
• The rings are clamped against the outer or inner ring and exert a slight axial pressure against the other ring
• After a certain running-in period, these trailing seals become non-trailing and then form a narrow gap seal
