Maintenance-free in rail transport due to lubrication-free lead screw drives

Rail industry

How can the wear on sliding doors in trains be reduced by 25%?

The number of passengers on public transport has been increasing steadily for 20 years. This is good news for the industry, but it also places an increasing burden on the rail network, trains and their individual components, such as sliding doors. Long-lasting lead screw drives which meet the high requirements, such as minimising wear and increasing service life are in demand. drylin lead screw technology is convincing and has already proven itself in many railway applications.

Can maintenance costs in bridging gaps be avoided?

How would it be if maintenance efforts and costs were reduced and regular lubrication became unnecessary? And what if efficiency and effectiveness increase significantly? drylin lead screw technology offers the perfect alternative to conventional metal lead screw nuts for railway technology. It is completely lubrication-free and maintenance-free and therefore ideally suited for 24/7 operation.

25% less wear

Our lead screw technology convinces in the test laboratory

The evaluation of the wear test for the product with the dimensions 10x3 made of stainless steel showed that our dryspin® thread Ds10x3 can achieve a wear rate up to 25% lower, a service life up to 25% longer and greater efficiency compared to the competition and the trapezoidal thread Tr10x3 .

30% longer service life

Thanks to the unique dryspin technology

The larger spaces between the individual dryspin threads result in a higher share (factor 1.3) of tribologically optimised polymer in the threads. More wear-resistant material and higher levels of efficiency are crucial for a service life that is up to five times longer compared to conventional high helix threads.

100% lubrication-free and maintenance-free

Ideally suited for applications in continuous operation

From railway doors and bridging gaps, up to track adjustment - the freedom from lubrication and maintenance of the lead screw drives enables their use in almost all areas of railway technology.By using the tribologically optimised, iglidur high-performance polymers, dust and dirt cannot stick to the lead screw drive. The dryspin technology is also one step ahead in humid environments: it is 100% corrosion-free. Therefore, a smooth operation is guaranteed throughout the entire application. Discover maintenance-free dry operation in the dryspin thread shop.

Saves weight by up to 88%

Low weight means energy efficiency

Weight saving is a major issue in almost all means of transport. Because less weight means less energy consumption, which in turn leads to a reduction in CO2 emissions. Developers from the rail transport sector want to become fully CO2-neutral by 2050.
Metal lead screw nuts are robust – and heavy. drylin polymer lead screw nuts offer the perfect alternative for many applications in railway technology. They are light, reliable and durable. Wherever low weight is important, our light lead screw nuts made of polymer are perfect, because you achieve a weight saving of up to 88%.

Save 50.9% of the cost

Trains are not luxury items, but an important part of our daily society and economy. The total costs of the application should be accordingly low. Metal lead screw drives are more expensive to buy and operate because they require regular lubrication and maintenance.
dryspin technology convinces in any comparison of prices. It not only distinguishes itself due to its several technical advantages over its metallic counterpart, but is also 50.9% more cost-effective.
