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.
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.
► Up to 50.9% more cost-effective than metallic sliding lead screw nuts
► Up to 69% compared to comparable plastic lead screw nuts
► Up to 50% compared to ball screw systems*
*Due to a deviating thread profile, lead screw & nut must always be replaced, even for the same thread size
► Available in seven different materials
► Very different types
► Save up to 50.9% in costs
► In 5 different materials
► High helix, trapezoidal and metric lead screws
► Up to 30% longer service life
► Special designs for every application
► Accessories for lead screw nuts & lead screws
►Our experts are happy to assist you in person
► What was needed:
no jamming or sluggishness during continuous sliding step operation
Lightweight, weather-resistant, few components, low clearance height, reduced costs
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.
The expert can quickly help engineers find the right lead screw system part for their application and will also predict service life.
The configurator enables engineers to quickly find the right lead screw and machine the pins from both sides. The application generates a dimensioned drawing of the configuration.
