junaspin is a thread specialist, focussed on trapezoidal lead screws, ball bearing lead screws, metric thread rods, round thread screws and special threads. The company is located in the technology region Karlsruhe, in the south west of Germany.
Easy Engineering: What are the main areas of activity of the company?
junaspin is a full service provider in thread technology. We are available from the first idea until serial production and we are also available after sales. We support our customer with life time calculation, building up prototypes, building up test rigs and with mass production.
E.E: What’s the news about new products?
junaspin invested in a standard product program of high helix lead screw units, available ex stock.
High helix lead screws are mainly used in application where high speed movements are needed, like opening and closing doors or applications for medical devices.
High helix lead screws are made by thread rolling. Instead of using just one start, like normal trapezoidal lead screws do, these screws have up to 20 starts. So you can realize a stroke up to 200mm with just one complete turn of the spindle.
These kinds of spindles close the gap between ball bearing lead screws, which are ideal for rapid movements and trapezoidal lead screws which are ideal for high loads.
In a lot of application, it’s possible to substitute ball bearing lead screw which lower the costs of a drive system up to 85%.
Smallest available size is SG5x4 (which means diameter 5mm and 4 mm stroke per turning), the biggest size is SG40x40. Versions with extreme high pitch, like SG18x100, are also available.
Spindles are available in stainless and carbon steel. Nuts are available in maintenance free plastic and brass. The nuts are available in cylindrical version and also in a flanged version. Special nuts can get realized also.
The portfolio is about 16 new dimensions. This new product program get completed through a special lead screw grease. This grease is developed especially for screw application. It helps to reduce wear, lowering friction and reducing the consumption of the motor. It’s also useable in food-, packaging- and medical application, because it’s coming including FDA approval.
E.E: What are the ranges of products?
The idea of junaspin is to offer a complete lead screw unit. Supplying a lead screw, lead screw nut, grease, ball bearing or pillow blocks, coupling and linear rails. If requested the linear axle can get supplied mounted and ready to use.
E.E: What is the state of the market where you are currently active?
Our products are used in different markets.
High helix lead screws are mainly used in application where high speed movements are needed, like opening and closing doors or applications for medical devices and furnitures.
Trapezoidal lead screws are used in packaging machines, screw jack units, solar industry, automotive industry, agricultural industry, furnitures, medical devices, lifts and in general mechanical engineering.
E.E: What can you tell us about market trends?
Business in Germany gets harder and harder. Politicians who hate their country, reduce wealth and deindustrialize the country more and more make the environment more difficult for companies. The appearance of Germany is hard to beat in arrogance and arrogance.
The next few years we will be busy restoring the damaged reputation of the Germans. After we kicked out our incompetent politicians, we must humbly develop new and better products, produce them flawlessly and make them more durable.
E.E: What are the most innovative products marketed?
With our Lead Screw Grease we are unique in the market. There are a lot of grease and oil available yet, which are „also” for lead screws, but none product was developed for such a specific application.
This grease is developed especially for screw application. It helps to reduce wear, lowering friction and reducing the consumption of the motor. It’s also useable in food-, packaging- and medical application, because it’s coming including FDA approval.
E.E: What estimations do you have for the beginning of 2024?
Automation will continue to progress in 2024. We support this technological progress with our products.
