High Helix Lead Screws now available ex stock
High helix lead screws are mainly used in applications 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 realise 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.
Junaspin invested in a standard product program, available ex stock in standard length. Special length can be cut within one day. Machining of the ends are available within 2-3 weeks.
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 realised also.
The portfolio is about 16 new dimensions. This new product program gets 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 applications, because it’s coming including FDA approval.
