Do you need to replace the race when installing new bearings?

When installing new bearings, it is generally recommended to replace the race if it shows any signs of wear, damage, or pitting. The race and bearings work together as a system, and using a new bearing with an old, worn race can lead to premature failure. If the race is in good condition and compatible with the new bearings, it may be reused, but careful inspection is essential to ensure optimal performance.
