They are used as safety- and function elements in order to damp speed and to slow down masses.
The damping speed of the adjustable dampers can be adjusted when the damper is already installed. |

In electronic devices, certain components may require one or more spring contacts to achieve reliable electrical connection.
Typical applications include:
- Diodes
- Delay lines
- Wave guide components
- Printed circuit boards
Bellows spring contacts are used where the connection cannot or should not be permanent, particularly when the parts are to be inserted, removed and re-inserted. The two types of spring contacts best suited for these applications are gold-plated wire mesh cylinders and gold-plated miniature metal bellows.
Bellows Type Contacts:
Servometer bellows type contact springs are manufactured from electrodeposited nickel, and gold plated to enhance their conductivity. They are flexible and dynamic, and designed to provide a lifetime of reliable interconnection. Furthermore, they can help overcome tolerance buildup and thermal expansion problems in critical assemblies.
The following characteristics make bellows type contacts superior to wire mesh cylinders:
- Minimal of self inductance
- Extremely low DC resistance
- Minimal of insertion loss
- Lifetime spring repeatability
- Only small forces are required (as low as 0.04 oz per 0.001 in. of travel) for compression
- Seamless and non-porous
Operating Conditions:
- Life expectancy from 100 cycles to infinite.
- For greater life cycles, the maximum compression is reduced by 20% for 100,000 cycles and by 30% for infinite life.
- Servometer Contacts can be safely used up to 260°F and maintain their full spring qualities. There is no low temperature limit.
- Our entire stock line is rated for a maximum current of 4 amps. |

TBA Mechanical Seals are available compliant with standard UNI EN 12756 (ex DIN 24960).
They are supplied with springs outside of the product, so they can be used in particularly dirty and/or viscous liquids and can be fitted to parallel shafts and sleeves. No shoulder or stepped shaft is required. |
|
Mechanical seals manufactured in a wide range of general services, made according to standard UNI EN 12756 (ex DIN 24960).
Using a conical spring is wound onto the shaft allows the seal to compensate greater positioning errors than usual and there is no risk of clogging when it is in contact with very dirty and/or viscous liquids.
This type of seal is available for both clockwise or anticlockwise shaft rotation. |

Double seals in the TB07 series have the same design-features as the "TB04" of single seals. Apart from the installation length of the drive collar, all fitting dimensions (d1 < 100 mm) conform with EN 12756 (DIN 24960).
Double seals to DIN 24960:
DIN specifies single seals in back-to-back arrangement. It is possible, therefore, to choose from the following combinations :
As Burgmann’s recommendation :
unbalanced/unbalanced (z.B. M7N/M7N)
balanced/balanced (z.B. H7N/H7N)
unbalanced/balanced (z.B. M7N/H7N)
