DIN – European Standards

The diin pressure should be spread out across oversized washers. It is important that the yield strength of the material is not exceeded; a contact pressure of max.

The screws can be made of a wide variety of steel grades, brass, or bronze. The contact will therefore be better if the surface is rough, has pressing lines, or has been knurled. Copper oxide has a considerably lower electrical resistance than aluminium oxide and a negative temperature resistance coefficient.

Deburring is not necessary. Depending on the individual case, we recommend consulting with us. Rubber and plastic industries The surfaces should be even but not polished. When the temperature rises, the conductivity of a connection between two oxidized copper surfaces increases.

Recommendation for drilling Cutting speed: However, the contact surfaces should be free of oxidation and grease. Paint and colour industries CUAL can be tin- and silver-plated.

Torque for the tightening of the screws and dimensions of the washers Screw dimensions. Deviating current loads can be converted using the factors listed in DIN In a completed connection, the actual contact area is significantly smaller than that of the total surface area of dij connection.

Health care technology If this is not the case, you must clean the contact surfaces. A slight improvement can be achieved here: Our offices will be closed from December 24, to January 2, inclusive.

Treatment of contact surfaces: Exaggeratedly flat surfaces are not necessary for the connection, since the connection is clean and fixed. Domestic and commercial equipment. Petroleum and related technologies The template should be as close as possible to the shearing edge so that the material is adequately supported.

In addition, sprung elements should be used that can maintain the required contact pressure. You have no items in your shopping cart.
