Nos paliers s’alignent… sur toutes vos attentes. General More than just conventional - not only words for us! Since more than 35 years SNR is a leading manufacturer of ball bearing units and thus has a large pool of experience in various applications for machine and plant construction. Besides an extensive conventional standard ran- ge SNR developed a variety of special custom-built solutions. That means different surface treatments, as e.g. special painting, zinc or nickel coating, various fixing or sealing systems for the bearing inserts, particular dimensions or housing design - just more than only conventional In this catalogue you will find the SNR standard range for ball bearing units with cast iron and pres- sed steel housings. Housings are made of grey cast iron or sheet steel. The surface of the grey cast iron housings is pas- sivated and painted for protection against corro- sion. Pressed steel housings are zinc-plated. SNR bearing inserts are equipped with forged rings. This forming technology is favourable for bearing life. The inserts are deep groove ball bearings with sphe- rical outer rings that can compensate misalignment and flexion of shafts to a certain extent. Fixing to the shaft is by means of set screws, eccentric lok- king collar or adapter sleeve. SNR gives in addi- tion the option for mounting in floating position. For surroundings with strong contamination bea- ring inserts with triple lip seal L3 are available. In addition there is an option to provide grey cast iron housing units with open or closed protective caps made of stainless steel. The SNR standard range also includes bearing units for high and low temperature. In case the capacity of the series 200 is not suffi- cient, the engineer can select different bearing units of the series 300. Here various shaft fixing options are available, too. In cases, where the customer can't find an appro- priate bearing for his application in this catalogue or the catalogues "SNR bearing units of stainless steel" or "SNR bearing units with thermoplastic housings" there still is the option to design a custom-built solution together with SNR. In those cases please contact one of our sales offi- ces. Finally you will find: SNR ball bearing units - more than just conventional.
