GOLDPLEX HP has a temperature range above our standard seals, in fact up to 325F with frequent relubrication. Our standard high temperature greases, SHC type has a long term usage of 350F and short term to 400F. These are better for "standard" high temperature applications. Also remember, high temperature applications, over 250F, require more than a grease change. Seals, ball fit and maybe housing fit should be adapted for the application.
