Hercules Grease Slipjoints (HGSJ)
Hercules Galvanized or Stainless Steel Grease Slipjoints (HGSJ) or (HSSJ) is the cheaper alternative to Hercuslip Composite Slipjoints (HSC). It is easily applied slip joint material, used on load bearing brickwork and under concrete slabs (see Fig 1-6). Unlike HSC, HGSJ and HSSJ are not designed to accommodate sliding face rotation of supported structures or to evenly distribute their weight. Most commonly Grease Slipjoints are used under cast in-situ concrete slabs and less critical structural components. Grease Slipjoints is a temporary solution compare to the design life and reliability of Composite Slipjoints. HSSJs would last longer due to the better corrosion resistance of Stainless Steel material compare to HGSJs. Both types eventually will seize up as the Molybdenum Grease dries up. That will depend from the working environment and it is unavoidable. However we are using the best available Molybdenum Grease to extend the design life of Slipjoints.
Materials
Galvanized Steel or Stainless Steel with Molybdenum Grease in-between for sliding and protection of sliding surfaces

Ordering
- Nine most commonly used types of HGSJ and HSSJ are represented in Table 1-7. Widthsare reflected in the Part Number types.
- Small quantities (1-5 lengths) of HGSJ and HSSJ are supplied in rolls (approximately 300-500mm in diameter) on a small skid, except for the Cavity Bridge Types, they are alwayssupplied flat.
- Medium and large quantities are suppled flat on a pallet in 3000 and 2400mm lengthsaccordingly.
