Attach bearings anywhere an axle needs to spin.

Axles must be supported by two bearings.

Use Rivets to Attach Bearings

1. Put the two pieces of the rivet together

2. Insert bearing rivets into holes from the metal side, not the rivet side (pictured above)

3. Push the rivet until the back of the rivet expands to hold the bearing in place

Your Turn

What kind of hole would use so an axle could spin in the hole?

What kind of hole would you use to attach a gear to an axle so the gear would spin with the axle? Gears and lock bars

have square holes so they can turn with the axle.

Bearing flats and pillow blocks have round holes so axles can turn in the holes.
