Steel Telescopic Covers
Arnold steel telescopic covers offer robust protection against damage to and dirt accumulation in guide ways. The steel telescopic covers, made from high quality special sheet steel, can be produced in a wide variety of forms. Special sliding and guidance mechanisms as well as appropriate mechanical damping elements enable high process speeds. In addition to this, easy replaceable wiper lips minimize maintenance. Guideway wipers are supplied in stand-ard lengths or in customized form to suit.

KABELSCHLEPP guideway protections systems boast a high degree of operational reliability, a long service life, and make use of innovative technical solutions.
From individual manufacture to series production – we have a solution.
The number of varieties is immense, no cover for a machine is exactly the same as any other.
Telescopic covers are generally produced from cold-rolled uncoated thin plates in thickness from 1 to 3 mm. In case of extremely aggressive environmental conditions (e.g. aggressive cooling lubricants), corrosion-resistant stainless steel plates may also be used.
For the selection of a suitable telescopic cover the speed is decisive. |

| There are limitless applications for Spiroflex's "Lead Screw Covers". Featured is the most widely used of all, machine tools, and how the Lead Screw Cover can be used to protect and preserve the most valuable of moving parts. Providing protection to an operator from hazards, the Lead Screw Cover can be used to cover many moving parts. |

n close cooperation with machine manufactures from all over the world, the Hennig GmbH develops, manufactures and improves the telescopic steel covers for all requirements and suitable for a variety of machine tools.
Whether horizontally, vertically, inclined or transversally - there is no mounting position for which there is no optimum Hennig cover. Any difficult guide geometry or unfavourable space conditions in special machines will be solved by individual designs. The robustness and reliability of our covers are convincing. Safety and economy are ensured by ingenious wiper systems.
All forms are made from rolled high-grade steel sheets from 1.5 mm to 3 mm thick. Corrosion-proof stainless steel can be used for extreme conditions (e. g. aggressive coolant).
Depending on the fittings, speeds of up to 100 m/min can be attained by steel covers of all shapes. Way wipers, gliders, rollers and damping elements are interchangeable. Gutters (preventing coolant entering the boxes) can be included in the design of different models.
Our HSC-Modules meet the steadily exacting requirements for high operating speeds and accelerations.
Hennig telescopic steel covers guarantee:
* Convincing technical solutions
* Functional reliability
* Durability
* Tight fit
* Increased protection against corrosion
* Tested standard components
* High-grade steel sheet
* Long-term supply of spare parts |

The standard designs are splashproof and suited for high traversing speeds.
We also offer innovative solutions for special applications.
Integral Gutter :
The gutter is formed as an integral part of the rear panel of the individual boxes. This version can be manufactured in a cover width of up to approximately 2000 mm with a 2 to 3 mm thick steel sheet. With a slope of at least 5¡, this form ensures an efficient drainage and prevention of
coolant entering the boxes.
Separate Gutter :
On special request, we can manufacture separate gutters for covers more than 2000 mm wide. In this design, a specially developed way wiper diverts the coolant along the inner side of the boxes. Due to its large cross-section, a separate gutter deflects the water optimally and even at a slope of at least 5¡ ensures the drainage of coolants entering the boxes. |

HEMA produces flexible protective systems for applications in widely differing industrial sectors. Apart from its core product of bellows, HEMA also possesses extensive specialist knowledge on various alternative solutions. High-quality steel covers are innovatively designed and efficiently manufactured by HESTEGO in a brand new production plant. The latest equipment and optimum processes guarantee constant, reproducible quality.
Whether providing new designs from absolute scratch, improving designs on existing cover applications, rebuilding old covers based on drawings or samples or refurbishing parts of damaged steel covers - HEMA does it all, in less time and at a low cost. Telescopic steel covers are the traditional form of cover for machine tools. They are used wherever an effective protection against the penetration of chips and other sharp-edged elements is decisive. The penetration of coolants can also be effectively reduced by design measures and suitable wiper systems. With their advanced technology, precise positional accuracy and high movement speeds, HEMA steel covers adapt ideally to the constantly rising demands of modern machine tools. |
