rubber bellows for vibration isolation due to a cryopump
Inquiry (采购产品): rubber bellows for vibration isolation due to a cryopump Dear Sirs I am looking for a rubber bellows assembly to meet the following requirements : One end of the bellows should fit to (come upon) a copper cylinder of 28 mm diameter and the other end to fit to anothe metallic part of 25 mm diameter. In order to fit our application, the bellows should have BOTH "cuff"-ends of 25 mm (1") cuff diameter and about 25 mm (1") cuff length, plus center segments to reach about 160-170 mm length when unextended. The material should be NEOPRENE LATEX , of about 0.2 - 0.3 mm thickness; its elasticity should allow that the ends (25 mm diameter) should pass over 30 mm (because of a flange on one of the metallic parts, but off the place covered by the bellows). The purpose of the bellows is to close the top of a cryostat and NOT to transmit vibrations to the cane with the sample holder, in a Moessbauer spectrometer with closed-cycle cryostat set-up. Expecting your answer, Regards, Neculai **** Hidden Message ***** Neculai Plugaru ESP Company: Universidad de Zaragoza Title: Dr Phone: 0034 976762524 Fax: 0034 976761957 E-mail: plug@unizar.es **** Hidden Message ***** plug@unizar.es
