At National Manufacturing Week 2010, the drive solutions group, SEW-Eurodrive will launch its new KES37 and RES37 stainless steel gear units. Based on the design of the existing 7-Series gear unit range, these two additions feature casings and shafts made from stainless steel, with a suitable enclosure for washdown applications. The KES37 and RES37 models are suitable for aseptic applications, where caustic/high-pressure wash-downs are required, or where there is potential for product contamination.
The stainless steel casings avoid the need for special coatings, thereby ensuring a long service life and lower life-cycle costs. Cleaning is assisted by the smooth design of the casing, which prevents build-up of contaminants. The lack of horizontal surfaces in the design also permits better drainage, and facilitates wash-down of the units. Furthermore, the new units feature up-rated seals that deliver a washdown protection rating, enabling these units to accommodate the hygienic manufacturing requirements.
Both the right-angle helical bevel KES37 and the in-line helical RES37 are rated up to 3kW and 200Nm. The KES37 is available in a wide variety of configuration options and user-specific requirements, including hollow shaft, shrink disk, TorqLOC and flange mounted design. The RES37 is available in a B5 flange-mounted design. Both models are available with a range of directly mounted stainless steel motors up to 0.75kW, or alternatively a third-party motor can be fitted via available stainless steel IEC adapters.
