The ferrofluid is in imperial size and is flanged. When the drive shaft is inserted into the bushing, the two O rings in the sleeve can compress the drive shaft, and the two form a static seal. The rotation of the drive shaft can drive the shaft sleeve to rotate together, and in order to prevent the drive shaft from slipping, the clamp at the end of the shaft sleeve needs to lock the shaft.
Suitable for vacuum sealing at medium and high speeds in high-temperature environments.
