Only sliding elements made of optimized dry-tech® high-performance plastics are used for our moving applications. Therefore, self-lubricating drylin® linear solutions can replace metallic recirculating ball bearing systems in almost all areas of use and cut up to 40% of the costs!
Due to the use of sliding elements made with high performance polymers, drylin® linear technology is extremely wear-resistant and durable, even when subjected to high mechanical loads.
Both precision and durable linear guidance are achieved with drylin® linear drives. The NOVASPORT grinding machine (see above on the right) creates an edge without any loss of required precision.
drylin® linear bearing systems are durable under various environmental conditions—they withstand dirt, humidity and liquids, high and low temperatures, severe vibrations, and hard shocks and knocks.
Unlike recirculating ball bearing guides, drylin® linear technology uses sliding elements made of high-performance polymers that prevent dirt and dust from adhering.
The mobile saw mill of Serra Maschinenbau GmBH was developed to be low-maintenance and easy to operate, regardless of harsh environmental conditions. Dirt-resistant drylin® linear technology helps the saw mill reach these requirements.
drylin® can be used in places where sand, chips and dust are present—the contact surface between the plastic sliding element and the guide simply forces foreign bodies out of the way, similar to the way a snow plough functions.
The materials used in drylin® linear guides are highly resistant to various media and have been tested for use under water.
Particularly in the food and beverage industry, certain hygiene requirements have to be met. To reach the requirements, machines and components must be corrosion-resistant, 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) is resistant, even when it comes in contact with seawater.
Conventional recirculating ball bearing guides mainly consist of metal, while drylin® linear technology is made of lightweight, high-performance polymers.
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.
High rates of acceleration and fast linear movements during printing can cause severe vibrations. The 3D printing system Kühling&Kühling was developed with drylin® linear technology to ensure successful noise-dampening operation. .
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 self-lubricating sliding elements and a linear bearing liner made of high-performance polymers, drylin® linear technology is exceptionally clean and hygienic.
A clean linear guide that meets the challenging hygiene and precision requirements in the pharmaceutical, biological, chemical and medical industries is essential for pipetting devices used by the University of Ljubljana.
