drylin® linear plain bearings - the cost-effective alternative to rolling bearings

Due to the use of sliding elements made of high performance polymers, drylin® linear technology is especially wear-resistant and durable - even when subjected to high mechanical loads.

Precision is one thing, robust linear guidance another With robust drylin® linear drives, NOVASPORT (see above on right) creates an edger for extreme conditions without any loss of the precision that is required.

drylin® linear bearing systems are robust under many conditions of use: they withstand dirt, humidity and liquids, high and low temperatures, severe vibrations, and hard shocks and knocks.

In contrast to recirculating ball bearing guides, drylin® linear technology uses sliding elements made of high performance polymers that prevent dirt and dust from adhering.

The mobile sawmill of Serra Maschinenbau GmbH has to work perfectly, be easy to operate and be easy to look after and maintain whatever the weather. drylin® linear technology is dirt-resistant.

drylin® can even be used in places where sand, chips and dust are to be found, the reason being that, similarly to the way in which a snow plough functions, foreign bodies are simply forced out of the way due to the contact surface between the plastic sliding element and the guide.

The materials used for the drylin® linear guides are highly resistant to various media and have been tested for use underwater.

In the food and beverages industry in particular, special hygiene requirements have to be met. Machines and components must be corrosion-free as in the case of this labelling machine.

The combination of highly alloyed stainless steel (e.g. 1.4571) with a high performance polymer (e.g. iglidur® X) can be described as resistant, even when it comes into contact with seawater.

Conventional recirculating ball bearing guides mainly consist of metal, whereas light, high performance polymers are used for drylin® linear technology.

A drylin® guide made of carbon fibre was used for a drone – The guide has the necessary stability while being robust and extremely light.

drylin® linear bearing systems are designed for low-height installation dimensions and low weight. The use of sliding elements made of plastic guarantees low mass for easy handling.

Thanks to their sliding elements, drylin® products made of high performance polymers have a noise output of 20 dB on average and are therefore around 4 times quieter than corresponding linear bearings made of metal.

A high rate of acceleration during printing and fast linear movements generate severe vibrations. The requirements for the 3D printing system of Kühling&Kühling, whereby low-noise, noise-dampening linear technology had to be installed, were fulfilled completely with drylin®.

drylin® linear bearing systems slide on plastic instead of rolling on steel balls. As a result, significantly less noise and vibration is generated.

Due to lubrication-free sliding elements and a linear bearing liner made of high performance polymers, drylin® linear technology is especially clean and hygienic.

A clean linear guide that meets the extreme hygiene requirements in the pharmaceutical, bio, chemical and medical industries is essential for pipetting devices that are used by the University of Ljubljana, which also requires a high level of precision for such devices.

All drylin® linear bearing systems operate without any external lubrication such as oil or grease and are therefore extremely clean. In cleanrooms, splashed grease and oil mist can be ruled out completely.
