Spring covers

Protection under extreme conditions

Spring covers protect spindles, columns, shafts, threads and rod guides reliably against contamination, chips and mechanical damage. They provide a good sealing function, and are self-cleaning if installed in a suitable position. High temperature resistance and resistance to chemicals guarantee reliable protection even under extreme operating conditions.

Spring covers Sample
  • Accident prevention for operating personnel from revolving spindles and shafts
  • Reduction in downtimes resulting from contamination
  • Increased machine service life
  • Some spring covers are also available for retrofitting

Installation positions

The conically wound spring covers automatically follow the motions of the machine. Made of high-quality blue polished steel or alternatively of stainless steel, they can be used in vertical, horizontal and inclined positions.

Vertical installation

When installed vertically, spring covers are mounted with the larger diameter at the top. This way the overlapping of the individual coils makes the spring covers self-cleaning.

Horizontal installation

When installed horizontally, conical spring covers are mounted with the larger diameter in the direction of the chip generation. With larger diameters or longer expansion, the maximum expansion is reduced to 60 % of the value for vertical installation.

Installation in inclined position

In addition to vertical and horizontal installation, installation in an inclined position is also possible. For small angles of incline above the horizontal the same conditions apply as in horizontal installation.

Installation of spring covers in series

By connecting several spring covers in series it is possible to deal with special requirements, such as extra-long traversing distances.

d = Shaft/spindle diameter
a = Outer diameter of the guide sleeve a ≤ D1 – 4 mm
D1 = Spiral inner diameter
D2 = Spiral outer diameter
c = Inner diameter of the outer flange c ≥ D2 + 6 mm
h = Flange height (0.6 x ZD ≤ h ≤ (ZD – 2 mm))
ZD = Compression
AZ = Extension/extension length

Selection & Retrofitting

Spring covers Example

Selection of the spring cover suitable for your specific application is generally based on the following criteria:

  • Internal diameter D1
  • Expansion AZ (vertical / horizontal)
  • Compression ZD

Some spring covers are also available for retrofitting.
