HRL 090 Frame

The HRL series from Nidec Drive Technology is a planetary product that excels in corrosive, high pressure washdown environments. Made completely from 303 grade austenitic stainless steel, HRL is a safe solution for servo drive systems close to or fully integrated in the process. A seamless, single piece housing helps reduce build-up of bacteria while its IP66 rating allows for high pressure cleaning with water, steam or caustic chemicals. HRL has flexible adaptation to standard B5 style servomotors as well as B14 style stainless servomotors. Available in three sizes and a complete range of reduction ratios, HRL is a robust, reliable, maintenance-free solution allowing our customers to reduce risk and increase productivity.

  • All-stainless construction
  • IP66 Ingress Protection with Viton seals
  • NSF H1 Synthetic Food Grade Grease
  • Mounting for standard servomotors with B5 flanges or stainless servomotors with B14 flanges
  • Cost-effective solution for highly corrosive environments with demanding washdown regimens
