Voltage withstand is a test property, not a specified continuous operating voltage. Torque strength is not a recommended installation tightening torque.
Dimensão
| Model | Overall height (mm) | Central band height (mm) | Marked diameter φ (mm) | Overall plan span as shown (mm) |
|---|---|---|---|---|
| 7100 | 30 | 7 | 26 | 30 |
| 7105 | 38 | 10 | 27 | 33 |
| 7110 | 45 | 10 | 32 | 40 |
| 7120 | 50 | 12 | 42 | 50 |
| 7160 | 60 | 12 | 44 | 50 |
The marked φ diameter and overall plan span are separate drawing dimensions. Do not use the model code as the height.
Guia de Seleção
Select the 71 model by height and plan dimensions, then choose its listed thread configuration. For 7120, the 8 mm thread option has a 12 mm depth and 12 ft·lbf torque strength; the 10 mm option has a 14 mm depth and 35 ft·lbf torque strength. Confirm the thread form and pitch when ordering; nominal diameter alone does not specify them.
Informações de Encomenda
For a quotation, specify the model, listed nominal thread diameter, quantity, thread form and pitch, insert material, insulating material and colour. Colour, inserts, material properties and thread specifications can be requested.
