Un fabricant américain de machines d'emballage alimentaire a éliminé les défaillances par corrosion et augmenté son OEE de 15 % grâce aux paliers linéaires en acier inoxydable LM12UU et aux vis à billes SFU1605 de Dongfeng, classés pour les environnements de lavage IP67.
Customer Challenge
A food packaging machinery OEM in the United States needed corrosion-resistant linear bearings and ball screws for a new high-speed packaging line rated at 200 units per minute. The previous linear motion components suffered corrosion after 6 months of daily washdown exposure, requiring frequent replacement and causing unplanned production stoppages during peak season.
Dongfeng Solution
Dongfeng supplied LM12UU linear bearings in stainless steel 440C construction with sealed ball retainers, paired with SFU1605 rolled ball screws featuring corrosion-resistant surface treatment. All components were rated for IP67 washdown environments. The company provided material declarations confirming FDA-compatible surface treatments and supplied accelerated salt-spray test reports showing 500-hour corrosion resistance.
Results & Valuealue
The stainless steel linear bearings and ball screws operated for 24 months without corrosion-related failures, extending the maintenance interval from 6 months to 2 years. Unplanned downtime during peak production season was eliminated. The customer reported a 15% increase in overall equipment effectiveness (OEE) and ordered components for 3 additional packaging lines within the same year.
