SNR - Industry SNR Stainless Steel Ball Bearing Units
General More Nos than paliers 35 years s alignent of experience sur toutes vos attentes. SNR has been a leading manufacturer of housed bearings for more than 35 years and thus has a large pool of experience in a very diverse range of applications in many industrial areas. In this catalogue you will find the SNR standard range for stainless steel ball bearing units. Housings and bearing inserts for these units are manufactured from stainless steel. The bearing inserts are grooved ball bearings with spherical outer rings that can compensate for alignment errors and deformation of the shafts to a certain extent. Fastening to the shaft is by means of setscrews or eccentric locking collar. The bearings are equipped with a high-performance seal and filled with grease suitable for use in the food industry (USDA H1 standard). SNR stainless steel ball bearing units are primarily intended for use in areas where moisture or aggressive media seriously degrade the service life of conventional ball bearing units made of cast iron and bearing inserts made of chrome steel, and thus render them uneconomical. SNR stainless steel ball bearing units are, e.g., particularly suitable for machines and plant in the food, pharmaceutical, and chemical industries. However, they also represent an ideal solution anywhere where frequent cleaning with water or chemical agents is necessary or the bearings are used outdoors. Although great care was taken during the preparation of this publication, we cannot accept any responsibility for any mistakes or omissions. Subject to technical change.

Applications Nos paliers s alignent sur toutes vos attentes. Ball bearing units made of stainless steel are used in areas where corrosionresistance is a must. In these areas where high atmospheric humidity or the requirement for periodic washdown of the equipment is necessary to prevent bacteria growth, conventional ball bearing units made of cast iron cannot adequately perform. To address these special applications, SNR offers a comprehensive standard range of ball bearing units made of stainless steel. Furthermore, to satisfy the requirements of the pharmaceutical and food industries all SNR ball bearing units made of stainless steel are filled with grease meeting the USDA H1 food-grade specification.

SNR ball bearing unit range SNR - Ball bearing units with cast iron or stamped steel housings The SNR Ball Bearings Units catalog contains the SNR standard range for ball bearings with housings made of cast iron and stamped steel. For many models there are various configurations available for the related shaft diameter. This variety of SNR ball bearings units provides the user with a suitable solution for almost every application. The grey cast iron and stamped steel housings can be combined with numerous bearing inserts to obtain, the optimal type of fastening of the bearing insert to the shaft (adapter sleeve, eccentric locking collar, setscrew or floating bearing). The designer can thus find the best solution in the SNR standard range for ball bearing units. To enhance shaft and bearing protection from contamination in harsh environments, it is possible to equip many SNR ball bearing units with protective caps made of stainless steel. These are available closed or openended with a double-lip seal. SNR - Corrosion-resistant ball bearing units with thermoplastic housings The ball bearing unit range in this catalog incorporate housings made of Thermoplastic PBT and bearing inserts of stainless steel or chrome-steel. The units can be equipped with protective end caps made of SR 50 (polypropylene), open with double-lip seal for through shafts or closed for shaft ends. The bearing units are used, among other areas, in the food and pharmaceutical industries with their high demands on hygiene and corrosion resistance of the materials used. For this reason all ball bearing units are lubricated with grease in accordance with the USDA H1 standard. Currently this standard places the most stringent requirements on the hygiene and purity of the materials used in the lubricant. 24
