- Examples of unilateral tolerances:
+ 0.05 + 0.05 - 0 0. 00 - 0.02
+ 0.00 + 0.02 - 0.05 - 0.05
(i) 30 mm (ii) 30 mm (iii) 30 mm (iv) 30 mm
2. Bilateral Tolerances:
- In bilateral tolerances, both the limits of size (maximum limit and minimum limit) are on either side of the basic size
- Examples of bilateral tolerances :
+ 0.05 + 0.05 + 0.01
- 0.05 - 0.01 - 0.05
(i) 30 mm (ii) 30 mm (iii) 30 mm
