Part 8: TOLERANCE

1 Unified recording of 3 main sizes:a Axis I:

- The ball bearing inner ring uses ø 35 k6 - The bearing outer ring uses H7 ∅ 40H7

- Install gears, pulleys, and couplings using H7/k6 ∅ 40H 7/k6

b Axis II:

- The ball bearing inner ring uses k6∅ 5 0 k - The bearing outer ring uses H7 ∅ 50H7

- Install gears, pulleys, and couplings using H7/k6 ∅ 52H 7 /k6
