SNR : SNC Pillow Block Housings

4 5Clamp the shaft horizontally (protect the shaft againstdamage in the area of the clamping). When using V-rings,slide those that are located between the bearing units(internal) onto the shaft. Later mounting is not possible.The bearings should be positioned on the shaft asdescribed in the Mounting the bearings section andcompletely filled with grease.Insert the pre-mounted shaft into the lower housing section.For the floating bearing version, position the bearingcentrally on the bearing seat. Distribute the remainingquantities of grease (table, Page 22) evenly in the lowerhousing sections.Locating ringsFor the fixed bearing version, insert the two locating ringson each side of the bearing in the lower housing section.Units with regulation discsIn units with a regulation disc, the regulation discs must be mounted on the grease drain hole side. The position of theshaft is specified in the table on Page 25. When using rolling bearings with adapter sleeves, it must be ensured that thegroove nuts are positioned on the lubricating fitting side. Tighten the two set screws with the appropriate tighteningtorques as set out in the table on Page 24 (this only applies to 500 and 600 series regulation discs).6 7When using V-rings, now slide those located outside thehousing onto the shaft. Position the lower housing sectioncorrectly using the alignment markings and slightlytighten the foot bolts.Insert the remaining round cords into the grooves on theupper housing sections and then insert the retainerscontaining the oil-soaked felt strips.8Position the upper housing section and tighten theconnecting bolts evenly to the tightening torques specifiedin the table on Page 21. Slide all pre-mountedV-rings with sealing lips to their final position next to thecontact washers. Grease the sealing lips first.Check the alignment of the bearing housing again andthen tighten the foot bolts to the appropriate tighteningtorque (table, Page 21).33
