Sprung - Import export

The combination of our very comfortable tennis surfaces (point elasticity) with a sprung floor substructure (surface elasticity) certainly offers maximum force reduction! Hall operators can advertise that their choice of sports flooring offers the maximum in terms of joint protection and force reduction! On the other hand, a sprung floor only develops its comfort when there is a lot of movement. Players who only move a little therefore feel no additional comfort! In terms of ball bounce (flatter) and general playing behaviour (e.g. acoustics), sprung floors are a matter of taste. As a rule, however, players quickly get used to the changed playing conditions. A compact sprung floor can be installed on top of the existing tennis floor covering, provided the surface is level. There is no need to remove and dispose of the old floor covering! If the surface needs to be refurbished, the bonded tennis floor can be removed.

Compression springs is the most common type of springs. The majority of compression springs are cylindrical and linear, but to this group belongs also conical, barrel shaped, tapered out ends and more. The design can be adjusted to fulfill a wide range of requirements concerning spring characteristic.

Wave springs developed to order: We work closely with you in the development of our wave springs for the intended application. Where necessary, we are pleased to assist you with processes ranging from dimensioning to verification to production. With the help of our specialist expertise, we will find the right solution for you together. We produce both single-turn and multi-turn designs with wavy and straight surfaces.

Lesjöfors’ range of standard springs consists of over 10,000 different items. Our highly efficient store of standard springs guarantees high delivery reliability. All our standard springs have been posted as 3D CAD models, and are available for downloading.

Westfälische Drahtindustrie manufactures steel wire for springs for use in a wide range of applications automotive, mechanical engineering, window and door equipment, agricultural technology, furniture industry, screen wire for the filter industry, various industrial products.

Check valves are used to prevent media from flowing back in systems or to protect equipment against media blow-back. The three types (with spring, without spring and COMPACT) allow for use in many different applications. The valve seat is supported by an O-ring and guarantees maximum safety and reliability.
