Hollow bars

Hollow bars:

Hollow Bars are often used for fittings and cylinder parts,  necessary in the creation of modern production and industrial technologies. Hollow bar is characterized by a shape similar to an elongated ring or a hollow cylinder. The purpose of the product determines the material from which the hollow bars are made. Depending on the material, we can distinguish among others: steel hollow bars, steel-brass hollow bars.

 

Hollow bars – features

Hollow bars offered by our store are characterized by high quality and endurance,  and allow you to build connections of any size. In addition, we can guarantee exact precision.

The product can be found in a dozen or so variants, eg: smooth, lubricated, cylindrical channel, intransitive and eighth spiral channel. After machining, hollow bars can be toughened through and grinded outside and in the hole. Hollow bars made of thin spring steel are used to mask untrapped and threaded holes.

The greatest advantage of hollow bars is their low price in comparison with bars. In addition, waste material during production is minimal. The finished product does not require many machining operations.

It should be mentioned that hollow bars are durable and can function for a long time in high and low temperatures. Their coefficient of friction is minimal, which also means a small resistance to movement.

Steel hollow bars do not show properties related to the interaction of chemical substances.

A product with a flange has the B designation, while the straight hollow bars are marked with an A feature. If they do not have any distinguishing features, they are ready for functioning.

 

Hollow Bars – application

 

Steel hollow bars are often used in the creation of cylinders and parts for machine parts. The product is used in places where the mounted part was dismantled, but in such a way that after removal no element protrudes from the ground. Hollow bars can be used with a metric bolt with a diameter equal to the diameter of the internal thread of a given hollow bar.

Protective hollow bars are installed in places where tubes pass through the building envelope, e.g. through the ceiling. In this type of hollow bar, there must not be any tube connections.
