Products intended for low pressure environments must be built to withstand the typically large pressure differentials and outgassing common to these environments. If you would like a gearhead designed for vacuum environments you can request a "V01" modification on the standard model. For example, if you would like the PS90-010-S2, you can request a quote for the PS90-010-V01S2. This customization includes the follow modifications:
- Remove shaft seals
- Use Krytox 240 grease in place of the standard oil
- Remove all labels and laser or mechanically etch only
- Vented, stainless hardware
- Use lock washers in place of Loctite
Although our gearheads that are designed for vacuum environments are not specifically vacuum rated, they follow best engineering practices and have successfully been used in environments down to 10-6 Torr.
