SNR : SNC Pillow Block Housings

Latest generation of SNCpillow block housingsThe SNC pillow block housing is a technologicaladvancement of our previous SNB and SNU series.The major abutment dimensions of the SNC seriescorrespond to the specifications in ISO 113/II:1994and DIN 736:1984 to DIN 739:1984.The bearing units are based on our two-part housing.By default, these are made of grey cast iron incompliance with DIN EN 1561 and are available indifferent sizes. On request, for particularly highloads, housings can also be produced from othermaterials, such as ductile iron, in the same dimensions.Each individual housing can hold bearings ofdifferent diameters and widths. They are primarilyself-aligning roller bearings.However, the crucial factor is the type of application.For example, if high speeds are required, selfaligningball bearings can be used. Self-aligningroller bearings are particularly well suited for highaxial and radial forces.The SNR standard range includes:• Double lip seal• Felt strip seal with retainer• V-ring seal with contact washer• Labyrinth ring seal• Taconite sealAll SNC units are designed for both through shaftsand for shaft ends.A cover plate is available for these versions, whichis inserted in the sealing groove in place of the seal.Combined with the various sealing elements, thisresults in a variety of possible designs, which makeup SNR's standard range. The shaft diameters arebetween 20 and 160 mm (special dimensions onrequest). The bearings with tapered bore inner ringsare attached to the shaft using an adapter sleeve.By contrast, bearings with a cylindrical inner ring liedirectly on the shaft.There are a wide variety of sealing options for thehousing due to the large number of practical applications.The most important factors are the speedsand the external influences that act on the unit.4
