Seal Groove Tolerances — ISO 3601
Look up O-ring groove dimensions and tolerances per ISO 3601. Select seal type and cross-section size to see groove depth, width, and surface finish requirements.
Groove Dimensions
Groove Depth Calculation
Typical squeeze: 15–25% for static, 10–20% for dynamic seals.
Standard Groove Dimensions (ISO 3601-2)
| d2 (mm) | Groove Depth Static | Groove Width Static | Groove Depth Dynamic | Groove Width Dynamic |
|---|---|---|---|---|
| 1.78 | 1.35 | 2.5 | 1.47 | 2.4 |
| 2.62 | 2.05 | 3.6 | 2.20 | 3.4 |
| 3.53 | 2.82 | 4.7 | 2.95 | 4.6 |
| 5.33 | 4.34 | 7.0 | 4.50 | 6.9 |
| 6.99 | 5.74 | 9.1 | 5.90 | 9.0 |
All dimensions in mm. Tolerances: groove depth ±0.05 to ±0.10 mm, groove width ±0.10 to ±0.15 mm depending on size.
Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
