The food industry puts very high demands on machine constructions, even the tiniest component has to comply with the hygienic rules. Therefore Enemac has developed several variants of couplings. For clean rooms, the torque limiter ECR and the bellows coupling EWC would be a good fit. The torque limiter ECR, made for torque ranges between 15 and 350 Nm is completely made of stainless steel, even the enclosed disc spring.
The bellows coupling EWC, available for nominal torques between 5 and 1300 Nm, consists of stainless steel bellows (1.4571), rust free hub (1.4301/V2A), as well as VA screws. Those elements get bonded by a patented micro-plasma-welding method, to avoid adhesive residue. But even for the not so highly challenging areas there are solutions such as types ECI, ECE and ECG, which are available on request in stainless steel. Here, the outer parts are made of stainless steel, while the disc spring inside is made of chemically treated steel. Even caped special versions can be supplied on request.
