SNR : SNC Pillow Block Housings

Structural detailsDuring development of our new SNC series, we have optimised many aspects of the housing. This optimisationis the result of our decades of application know how for bearing housings. We have incorporated avariety of practical details that make mounting easier and safer for the user and guarantee maximumreliability. The FEM-optimised housing provides additional benefits including:Strength properties andheat dissipation:The circular ribbing on thehousing body gives theSNC housing excellentform stability and rigidity.Furthermore, this structuralfeature helps to optimizethe vibration behaviourand heat dissipation of theunits.Heat dissipation:The support surface in thefoot of the SNC housingensures extremely efficientdissipation of operatingheat.The X-shaped supportsurface and the crosspiece in the housing footstrengthen the bearing seat substructure and thussupport the construction at a critical point.Connection bolts:On SNC pillow blockhousings, bolts with alarger diameter than oncomparable housingsare used to connect theupper and lower sectionsof the housing.This enables higher radialloads to act on thehousing cap.Mounting holes:The holes incorporatedinto the underside of thehousing foot simplify exactalignment of the units inseries production.Dowel pins that are preinstalledin the mountingsurface as set out in thetable (see page 26) indicatethe exact position. If modificationof the housingis necessary, the mountingholes can also be used for alignment on a processingmachine with no problems.6
