Spring Into Perfect Protection
STABILASTIC Telescopic Springs ensure the protection of ballscrews, threads and guide columns against dirt, swarf and mechanical damage.
HENNIG Telescoping Springs are available in a variety of sizes designed to meet your specific application. A Quote Request form is available in the Downloads section.
- Telescopic springs made of hardened high-grade spring steel ensure an excellent protection against dirt, swarf and mechanical damage even when fully extended.
- A special manufacturing method and optimal resilience ensure an easy compression and extension. Horizontal springs have a minimal sag and vertically used springs only a slight lateral deviation.
Minimum overlap (of the individual windings) of 40%.
Winding-on types are available up to the size 54/1120/120.
Easy assembly by pushing the springs over the machine parts.
Assembly And Maintenance:
Regular flanges and collars are sufficient for the location of the spring ends. However, these items are not supplied by Hennig.
The minimum diameter of the take-up collar D3 must not be smaller than indicated. If the inside diameter of the take-up collar D3 is too small, or if the outside diameter of the centering flange D4 is too large, the spring will have a tendency to jam.
For horizontal applications, we recommend to install the Stabilastic springs with the large diameter nearest to the swarf accumulation area and for vertical applications, with the large diameter at the top. The maximum sag in horizontal installations will be approx. 2 – 3% of the maximum mounting length.
dmax = Maximum diameter of Shaft/Screw
D1min = Inside diameter
D2min = Outside diameter
D3 = Inside diameter of the centering sleeve (D2 + 2mm)
D4 = Outside diameter of the centering retainer (D1 - 1mm)
Lmax = Maximum extended length
Lmin = Minimum extended length
Strokemax = Maximum travel
