Just modelling a rotary feedthrough for my vacuum lid using off the shelf items. Did not test whether the “reversed” rotary shaft seal will hold the vacuum. It consists of:
- 10mm ground shaft with machined groove for circlip / e-clip
- 61900-2RS1 – Single Row Deep Groove Ball Bearing. 22x10x6mm
- Standard rotary shaft seal 10 x 19 x 7mm. NBR or Viton / FKM.
- Standard nylon insulation bushing
- 32mm hex
