摘要： The invention relates to a rotary seal chuck of an optical fiber preform rod deposition lathe, comprising a fixed socket sleeve and a rotary shaft. The fixed socket sleeve is provided with a central hole base. The central hole base bears the rotary shaft through a bearing. An end of the central hole base is connected to an air hose. The rotary shaft is a hollow rotary shaft provided with a through hole. One end of the through hole communicates with the air hose, and the other end of the through hole is provided with a liner tube connecting sealing hole base. A magnetic fluid seal ring is disposed at a joint between an inner side of the rotary shaft and the central hole base of the fixed socket sleeve, to form a rotary dynamic seal. An outer side of the rotary shaft is connected to a rotary driving disk.
