Heavy-duty ball screw drive
Extreme travel speeds possible
Thomson Industries has added a high speed option to its range of heavy duty ball screws. With a diameter of 50 mm and an exceptionally high lead of 100 mm, the new ball screw supports high travel speeds in applications requiring a dynamic load capacity of up to 202.4 kN.
"The new high-speed ball screw has a much higher pitch, which increases the distance traveled in one full revolution and consequently increases the travel speed. Even under extremely dynamic requirements, high loads can now be moved quickly, increasing potential machine throughput and productivity," says Thomas Schwertner, Product Manager for Ball Screws at Thomson.
The new 50 x 100 mm high-speed ball screws can be used to optimize motion applications where high forces are required for lifting, pushing or pulling at high speeds, for example:
- Winding machines that require fast sideways movements to ensure tight winding of steel cables, large cables or sheet metal.
- Machine tools for high-speed cutting processes.
- Injection molding equipment and metalworking machines where ball screws move heavy loads over short strokes.
- Metal pressing and forming, including riveting presses, servo presses, tube and sheet metal bending machines.
- Punching machines that require short strokes and high speeds.
As with Thomson's existing standard range of heavy-duty ball screws, the new size is characterized by high load capacities, smooth running, precision and long service life over long travel distances. The new high-speed ball screws are available with either single or double nuts. Preloaded versions are available on request, as are special versions adapted to customer-specific applications by Thomson engineers. The lead accuracy ranges up to 12 µm over 300 mm.
