The TDU Series are rotary feedthroughs enabling objects in vacuum chambers at ultra-high vacuum pressure to be rotated manually from the vacuum system's atmosphere side. When the handle on the atmosphere side is turned, the rotation is conveyed through a bellows to rotate the shaft on the vacuum side.
|Shaft/handle rotation ratio||1 : 1|
|Drive shaft diameter||5mm diameter||8mm diameter|
|Leak rate||1.3 x 10-11 Pa·m3/s max.|
|Bake-out temperature (*1)||150ºC max.||250ºC max.|
|*1||Can't be turned while heating. (After heating, can't be turned until chamber has returned to room temperature.)|
