1. Trial run at 120% rated speed for 30 minutes in a simulated environment, check for deformation.
2. Empirical rule: long‑term operating temperature should be <80% of glass transition temperature (~143°C).
3. Whitening of cage surface indicates lubricant incompatibility – switch to PFPE oil.
4. Cage life can be estimated using fracture mechanics models (crack propagation).
5. Speed limit can be calculated from density and strength values, using FEA + multi-body dynamics.
