Ziller GmbH & Co. KG has been producing metal seals for roller bearings, the NILOS ring, for more than 60 years. The NILOS ring is the ideal solution for your sealing problem. Agencies in more than 30 countries ensure a high availability of our products. NILOS-Rings provide practical protection for ball and roller bearings against contamination by dirt and debris, including tough abrasive particles that can cause equipment to malfunction and productivity to be lost. These all-metal seals are ideal for grease-lubricated anti-friction bearings in industrial environments that routinely generate excessive contaminants, such as those conditions encountered in the mining, paper, agriculture, construction, and
automotive industries. Creating an effective space-saving seal for ball and roller bearings even in the harshest operating conditions, NILOS-Rings offer a simple and easily incorporated method to help improve bearing performance and extend service life.
