H-RE

低オーバーハングモーメント用高性能、低モーメント設計(API 671およびISO 10441)

H-RE series couplings are designed for medium- to high-speed turbomachinery applications where low overhung moment and light weight with a high degree of reliability are critical. The couplings are manufactured in high alloy steel, with high-strength stainless steel flexible elements, supported by aircraft standard fastenings. The couplings are generally balanced to API 671 or similar, with pilot location to retain a very high level of repeatability.
