Q: How often should these be changed?
A: Roughly every 400 - 600 working hours. This is because they lose their elasticity and do not grip evenly and precisely any more.
Q: What is the difference between standard type and ultra precision type?A: The difference is in the run out rating with ultra precision being twice as accurate as the standard type.
