Rotary feedthrough, DN 25 ISO-KF

Image similar

Hardened shaft made of stainless steel
With FKM shaft seal and ball bearing, greased to be suitable for vacuum
The rotation speed can be increased by up to a factor of two if reduced service life is acceptable
With through shaft for directly transmitting high torques
With integrated FKM O-ring, installation without additional seal
Tightness static: 1 x 10^-9 mbar l/s
Tightness dynamic: 1 x 10^-9 mbar l/s to 5 x 10^-7 mbar l/s
When designing a rotary drive, take care that the rotary feedthrough is not the weakest component of the assembly
Inadmissible loads damage the rotary feedthrough
Do not apply force when sliding the coupling piece over the shaft. Consider the admissible levels of axial and radial force.
