1. Speed limit can be determined from oil film forces between pockets and rolling elements.2. Temperature effects on strength are openly available.3. Dark spots on brass surface after operation indicate lubricant corrosion – change oil type.4. Short‑term temperature allowed up to 180°C, but above 150°C check hardness every 500 hours.5. Correction factor: multiply calculated limiting speed by 0.85 as practical safety margin.
