Nilos India Pvt Ltd offers a wide range of metal seal rings for bearings. The range of Nilos ring caters to every type of grease-lubricated roller bearing sealing arrangement to significantly extend bearing life. The metal sealing ring is simply clamped to either the outer or, preferably, the inner bearing ring, with the sealing lip making direct contact with the bearing face. There are no other sealing media, such as, rubber or fibre involved. The shaft is only used as a concentric location when fitting and is not used as a sealing surface. Nilos rings are suitable for most speeds and are available in sizes to suit most standard bearings. A special Z-type ring is also available to provide exceptional sealing and therefore longer bearing life in very dirty or damp conditions. These seals are for use with Z or RS type bearings and are available for both inner and outer sealing. Nilos sealed rings need minimum spaces because of the small overall height. A comprehensive range is available ex-stock from Ziller GmbH & Co KG, Germany.
