Bellows covers

We supply a wide range of bellows covers. Our bellows are divided into four categories:

  • Rectangular bellows
  • Polygonal bellows
  • Homogeneous bellows
  • Telescopic bellows

 

More information regarding different bellows models and the solutions best suited to your needs is available in the type-specific sections on this page.

Rectangular bellows

Benefits

Structure

Each pleat can be equipped with a PVC frame, which guarantees the stability of the shape and the dimensions. The protective cover and the PVC frame are either welded or sewn together. A welded seam is permanently tight and provides oil-resistant protection, while a sewn seam is suitable for heavy mechanical duress. The conductor and the outer frames are manufactured to the customer’s dimensions and requirements.

Type Materials
002 Woven polyester fabric coated with polyurethane on both sides
Thickness 0.20 or 0.40 mm
Trickle-resistant
Oil- and emulsion-resistant
0016 Specially woven fabric gummed on both sides
Flame-proof
Excellent resistance to oil, fuel and chemicals
Specially designed for use with lasers

Polygonal bellows

Benefits

Structure

Polygonal bellows are available in hexagonal (Figure 1), octagonal (Figure 2), dodecagonal etc. versions. Alternately facing pleats provide excellent stability in large dimensions. These bellows guards are multi-layer laminated, which means that the woven textile fabric is glued to the inner material, thus guaranteeing stability and strength in large dimensions. These layers are further attached to a special outer material.

Type Materials
Polytex Polyurethane coated polyester fibre
Putex Silicone elastomer coated polyamide fibre
8 Cotton fibre, plastic coating
10 Cotton fibre, graphite coating
11 Cotton fibre, aluminium coating
11 A Fibreglass fabric coated with aluminium on one side
Other materials on request

Homogeneous bellows

Benefits

Structure

Each pleat is equipped with a shape-retaining PVC frame. The protective cover and the PVC frame are either sewn or welded together. Welded seams are tight and oil-resistant, while sewn seams withstand heavy mechanical duress.

  • 1 – Outer frame
  • 2 – Protective cover
  • 3 – PVC frame

Additional Information

The shape of the cover is designed to meet the customer’s specific needs. Our technical support team will identify the best possible form to meet your requirements. Upon request, we can also install additional rollers and sound-absorbing strips.

Type Materials
002 Woven polyester fabric coated with polyurethane on both sides
Thickness 0.20 or 0.40 mm
Trickle-resistant
Oil- and emulsion-resistant
0016 Specially woven fabric gummed on both sides
Flame-proof
Excellent resistance to oil, fuel and chemicals
Specially designed for use with lasers

Mounting methods

The mounting method and the shape of the outer steel or PVC frame are selected in conjunction with the initial order, based on the customer’s drawing (Figures 1–3) or with the help of an adhesive tape tested by us (Figure 4).

The benefits of self-adhesive mounting

Flexible telescopic bellows

Benefits

Structure

The sturdily articulated shaft runs parallel to the ridges of the pleats. The telescopic plates are connected to the articulation without gluing, either with or without additional compression. The number of telescopic plates depends on the recommended extension of the cover. The method of attaching the outer telescopic plate depends on the application and environment of the bellows cover.

Frequently asked questions

Maxjas Oy supplies way and bellows covers, chip conveyors and way lubrication equipment, machine guards, cable channels and other accessories for machine tools. We offer extensive maintenance services for way covers for machine tools and comprehensive life cycle services for our way covers.

At the latest, way covers should be serviced when they become visibly worn, dented or damaged. However, maintenance is best done pre-emptively, which is why Maxjas recommends regular, annual maintenance for way covers. By following that approach, the covers will last longer and production is shielded from unexpected shutdowns. 

If you do not know whether your way covers require maintenance or not, you can arrange for Maxjas to evaluate the condition and remaining lifetime of the covers free of charge.

In terms of maintenance of way covers, we replace section wipers, smooth section surfaces, replace any worn or damaged slides, bearings, brass and other parts. Each repaired cover is tested before return to the customer. Before each maintenance service, the client is given a cost estimate and details of the work to be done. On request, we can also carry out installation after maintenance.

We can procure way covers for any machine. We can take the measurements from the old cover and provide a new one quickly and at a competitive price.

Our life cycle service helps companies to get a better understanding of maintenance as a whole and to be prepared for the next step in maintaining their way covers. With our life cycle service, we identify and classify the way covers sent to us according to their condition. When the cover’s next estimated maintenance date is due, we already know what work needs to be carried out. 

This enables us to accurately monitor the development of the way cover’s condition and provide a new cover for our client in time, before the way cover reaches the end of its life. This in turn creates continuous savings for our clients and prevents unnecessary production downtime.
