Motor Bearing Locations

Below is the motor diagram showing the three ceramic bearing locations referenced throughout this guide.

Before You Begin

You will need

• Flat blade screwdriver
• Clean, dry cloths
• Replacement Foil Drive ceramic and stainless-steel bearing(s)
• Bearing press tool (included with bearing purchase)
• Loctite® retaining compound:
  • Essential: Loctite 680

You may also need

• Small hammer

Safety Information

Broken ceramic bearings can produce very sharp fragments.

If removing a damaged bearing, always wear:

• Safety glasses
• Protective gloves

If the ceramic housing is difficult to remove, carefully use a flat screwdriver and light hammer taps to crack the ceramic housing and release it.

Securing Loose Bearings

Apply Loctite 480 around the outside of the bearing housing where it contacts the stator. 

You must use Loctite 480 to secure the bearings to the stator before use. Failure to use Loctite 480 may result in damaged bearings or stator.

Important: Ensure you do not get any Loctite on the centre of the bearing, as this will seize the bearing, causing damage when the motor is next used.

Watch the video below for the correct application method.

Important: This instructional video below is outdated. 

Ensure the stainless-steel bearing is used in position 1 (outer most bearing, see graphic above for reference), for all Gen2 systems. Failure to use a stainless-steel bearing in position 1, will cause bearing failure when in use and potentially cause significant damage to your motor.

Common Questions

How can I prevent the bearings from popping out?

When reinstalling the rotor onto the stator, always use both hands to slowly guide it into position. Once the magnets begin to engage, prevent the rotor from snapping onto the stator, as this can damage the ceramic bearings.

How do I know if my bearings need replacing?

If the inner race of the ceramic bearing has movement in it, it is time to replace your bearings! You can test this by putting your little finger or a pen in the centre of the bearing and lifting up gently.

How long should I wait before using my motor?

Always allow a minimum 24 hours for the retaining compound to fully cure before operating your motor.

I don't feel confident doing it myself, does Foil drive have a service centre who can do it for me? 

Yes! We have a service centre in Florida, USA and at headquarters in Adelaide, Australia.
