Zusammenfassung:	PURPOSE:To impart superior corrosion inhibiting power and oxidation stability to a roller bearing without deteriorating the acoustic or vibrating characteristics of the bearing at the time of intermediate anticorrosive treatment of the parts of the bearing by specifying the compsn. ratio of a water-soluble corrosion inhibitor consisting of hydroxyalkylamine salts of synthetic sulfonic acid and aliphatic carboxylic acid. CONSTITUTION:The compsn. of this corrosion inhibitor consists of 5-90 pts.wt. hydroxyalkylamine salt of synthetic sulfonic acid and 20-95 pts.wt. hydroxyalkylamine salt of aliphatic carboxylic acid. The hydroxyalkylamine salt of synthetic sulfonic acid is distinguished from amine salts of petroleum sulfonic acid, etc., and it is obtd. by sulfonating an alkyl arom. compd. and carrying out conversion into the hydroxyalkylamine salt. This hydroxyalkylamine is, e.g. mono- or diethanolamine, N-beta-aminoethylethanolamine or diisopropanolamine.
