Series 80Download PDFCatalogue No.:UT-80 | Revision 00

This is the basic standard design. The central spacer is drop down type. Whole spacer assembly is spigotted on the end hubs to ensure concentricity and excellent dynamic balance. For a given OD the hubs have comparatively large bore capacity resulting in selection of coupling which is compact and has high Power/Weight ratio. Spacer Assembly/disc packs can be replaced without having to shift either driving or driven equipment.
