Nilos india offers metal seal rings for bearings. The range of nilos rings caters to just about every type of greaselubricated roller bearing sealing arrangement to singnificantly 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 nilos 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. Advantages: ring sealed: minimum spaces needed because of the small overall height; nilos - rings are comparatively cost effective sealing elements; the operating temperature range is between minus 40º and plus 140º; grease retained in the bearing; foreign matter cannot enter the bearing; for nilos ring used for grease lubricated bearings, occasional splash water does not affect the sealing effect; during the running-in-period, nilos rings are contact seals but approximately after 24 hours they run frictionless. A comprehensive range is available ex-stock from ziller gmbh & co kg, germany.
