Machine Tool Bellows for Way Cover Protection

Bellow Covers

Designed to protect guide-ways and machine components and constructed using lightweight material, bellow covers are ideal for fast travel applications. Their high compression ratio also makes accordion way covers ideal in limited space.   

Our bellows are made exclusively from high-quality plastic fabrics and foils. We select the cover material and processing according to the design ambient conditions. Decisive factors are the mechanical and thermal strain of the bellows as well as the type of swarf, chips, and aggressiveness of the agents used.

Our product range includes simple dust protection, sophisticated designs featuring extension systems and/or lamellas, as well as special designs for laser machines.  To maintain our high quality standards, all materials used are checked and developed by our own R & D departments. Hennig offers excellent productivity and security for your machine.

BELLOW TYPES

BELLOWS OPTIONS

The dynamic properties of modern drives make heavy demands on all bellows. With Hennig, you can adapt every detail of the friction, extension and durability properties of your bellows to your requirements.

Bellow Cover Example
  1. End Frames
    End frames, mostly made from steel or aluminum, connect the bellows with the machine. Hennig offers various fastening solutions for the adaptation to different bellows and machine interfaces.

  2. Intermediate Frames
    Intermediate steel frames are used to connect the various elements, especially when extension limit systems are required. The intermediate frames are fastened to the bellows with a clamping rail. The intermediate frames can be guided by either plastic or brass rollers or gliders.

  3. Guide Frames
    The guide frames provide the bellows with the necessary stability and enable a precise operation, even at high speeds. They are made from PVC and are directly welded to the cover. The shape of the frame is adapted by Hennig to the design required.

  4. Rollers
    Rollers are used in large and heavy bellows. They minimize friction and ensure excellent running properties.

  5. Coupling Rail
    Necessary for medium and large bellows with a high number of folds in order to connect the single bellow elements together. Connected inside and outside.

  6. Lamellas
    Fixed or hinged, stainless steel lamellas can be added to protect the bellows against hot, sharp-edged swarf, or mechanical strain.

  7. Scissors
    Scissors are used for high traversing speeds. This allows an even extension of all elements across the whole extension length. As a result, the folds are less strained and the durability of the bellows is prolonged.

  8. Half Scissors
    With half-scissors, the individual elements can be extended successively depending on the necessary extension length. Since the folds are not loaded up to the theoretically possible extension limit, it also has better durability.
