Double lip seal mountingSC..DS1 2Securely position the lower sections of the housings.Insert half of the seal into the sealing grooves on eachlower housing section. In units with an internal shaft end,only one seal is required in total. The cover plate SC..ECis used instead of the second seal in this case.Add lubricant to the cavity between the two sealing lips.30
34Clamp the shaft horizontally (protect the shaft againstdamage in the area of the clamping). The bearings shouldbe positioned on the shaft as described in the Mountingthe bearings section and completely filled with grease.Insert the other halves of the seals into the sealinggrooves on the upper housing sections and add lubricantin the cavity between the two sealing lips.Units with regulation discsIn units with a regulation disc, the regulation discs must be mounted on the grease drain hole side. The position ofthe shaft is specified in the table on Page 25. When using rolling bearings with adapter sleeves, it must be ensuredthat the groove nuts are positioned on the lubricating fitting side. Tighten the two set screws with the appropriatetightening torques as set out in the table on Page 24 (this only applies to 500 and 600 series regulation discs).5 6Insert 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 on Page 22) evenly in thelower housing sections.Locating ringsFor the fixed bearing version, insert the two locating ringson each side of the bearing in the lower housing section.Position the lower housing section correctly using thealignment markings and slightly tighten the foot bolts.7Position the upper housing section and tighten theconnecting bolts evenly to the tightening torquesspecified in the table on Page 21.Check the alignment of the bearing housing again andthen tighten the foot bolts to the appropriate tighteningtorque (table, Page 21).31
