KJLC Ferrofluid Rotary Drives - 2

KJLC Solid Shaft Rotary Feedthroughs (Thread Mount) These ferrofluid rotary feedthroughs are sealed by a fluorocarbon oring. The operator mounts these drives to the vacuum chamber by screwing them into a corresponding threaded hole. On some models the drive’s threaded end is inserted through a suitable diameter hole in the chamber wall and retained with a nut. Some models are threaded only part way. They will accommodate various wall thicknesses when used with a sleeve or spacer over the unthreaded portion so that the nut compresses the o-ring. with the thread, the feedthrough has a flat...

KJLC Solid Shaft Rotary Feedthroughs (CF Flanged) Designed to provide rotary motion under high vacuum, these ferrofluid feedthroughs have ConFlat-compatible (CF) mounting flanges. Normal helium leak detectors capable of detecting 1 x 10-11 std cc/sec of Helium flow detect no leakage for CF mounts under static and dynamic testing. CF flanged rotary motion feedthroughs routinely operate in the 10-6 torr range and, when properly prepared & installed, may be used to mid 10-10 torr. Kurt J. Lesker Company Enhanced ordering tables Even more stringent security Easier to use navigation All new...

KJLC Solid Shaft Rotary Feedthroughs (O-Ring Flanged) These ferrofluid rotary feedthroughs are sealed by a fluorocarbon o-ring. The operator mounts these drives to the vacuum chamber by placing them in a suitable smooth-sided port in the chamber wall and using a capture nut. Some models are threaded only part way. They will accommodate various wall thicknesses when used with a sleeve or spacer over the unthreaded portion so that the nut compresses the o-ring. In vacuum practice, the o-ring is compressed against the vacuum chamber's inner surface to limit virtual leaks. As shown in the...
