Further Details
Disc Springs are used in all types in all types of applications
Disc Springs are classified into 3 groups as given in the table:
Group | Thickness of single disc In mm | Single disc with Ground ends & reduced material thickness (t') |
1 | less than 1.25 | No |
2 | From 1.25 to 6 | No |
3 | Over 6 upto 14 | Yes |
Thickness Tolerances:
Group | t or t' (mm) | Tolerance for t (mm) |
1 | 0.2 to 0.6 >0.6 to <1.25 | +0.02/-0.06 +0.03/-0.09 |
2 | 1.25 to 3.8 >3.8 to 6.0 | +0.04/-0.12 +0.05/-0.15 |
3 | >6.0 to 14.0 | +0.10/-0.10 |
Free Height Tolerances:
Group | t | Tolerance for t (mm) |
1 | <1.25 | +0.10/-0.05 +0.03/-0.09 |
2 | 1.25 to 2.0 >2.0 to 3.0 >3.0 to 6.0 | +0.15/-0.08 +0.20/-0.10 +0.30/-0.15 |
3 | >6.0 to 14.0 | +0.30/-0.30 |
The tolerances on spring load:
Group | t | Tolerance for t (mm) |
1 | <1.25 | +0.25.0 - 7.5 |
2 | 1.25 to 3.0 | 0.15 |
>3.0 to 6.0 | - 7.5 | |
3 | >6.0 to 14.0 | + 5.0 |
