Rotary feedthrough, elastomer-sealed
- 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.
