· Speed limit can be determined from oil film forces between pockets and rolling elements.

· Temperature effects on strength are openly available.

· Dark spots on brass surface after operation indicate lubricant corrosion – change oil type.

· Short‑term temperature allowed up to 180°C, but above 150°C check hardness every 500 hours.

· Correction factor: multiply calculated limiting speed by 0.85 as practical safety margin.
