Spherical Bearings
Only one type of spherical bearing (Aurora AWC-4T) and one type of rod end bearing (Aurora ASM-4) are used
throughout the control systems. Those bearings are maintenance-free, i.e. do not require lubrication.
If a bearing develops play exceeding 0.5 mm in either direction, it has to be replaced.
Manufacturer:
Aurora Bearing Company
Montgomery, Illinois 60538, USA

Inspection Criteria:
Replace bearings, if play in any direction exceeds 0.5 mm, in accordance with 5-06 item 3.
Removal of bearings:
A If outer race is loose towards seat, pull or push out using any bolt, or carefully tap out.
B Bearings are secured with Threadlock Loctite 243.
To soften the Threadlock:
1 - heat up an AN3 bolt, using a heat gun, to no more than 200°C/400°F
2
– push the bolt in the bearing, let the heat sink in for 30 seconds
3 – use a plier to pull out the bearing, holding on the bolt
CAUTION: Bearings that have been removed using this method have to be replaced!
CAUTION: Make sure that surrounding composite structure does not overheat,
no discernible smell / smoke!
In case of overheating, contact Game Composites!
Installation of bearings:
1. Remove all residue of old Threadlock
2. De-grease surface with solvent
3. Apply a thin film of Threadlock on the bearing seat, and the outer race (contact surface) of the bearing
4. Push bearing in place, using a tube pushing on the outer race of the bearing.
