SCHOCK® telescopic slides in detail.
Structure of a roll-formed telescopic slide with full extension or over-extension
- Outer rail
For mounting to the cabinet or housing - Middle rail
Extends the travel to full or over-extension - Inner rail
Attached to the extension element (e.g., drawer) - Ball cage
Secures the ball bearings for smooth, stable operation - Ball mix
With AIR MOTION technology – for exceptionally smooth and quiet operation - Function
Depending on version, e.g., with soft-close self-closing or quick disconnect
Operating temperatures of our telescopic slides from the standard range
The operating temperatures of our standard telescopic slides are -20°C to +70°C.
When using a soft-close self-closing mechanism, the operating temperatures are +10°C to +40°C. (Low-temperature applications are realized with specially developed dampers. Please contact our customer advisors for this.)
For our milled super heavy-duty telescopic slides, the operating temperatures are -40°C to +200°C.
Extension variants
SCHOCK® telescopic slides
Partial extension (up to 75% extension length)
Consisting of 2 profiles – compact solution for limited installation space.
Partial Extension, Double-Sided Extendable (up to 75% Extension Length)
Consisting of 2 profiles – a compact solution for limited installation space.
The telescopic slide extends on both sides.
Full Extension (100% extension length)
With 3 profiles – allows complete access to the drawer.
Over-extension (up to 100% + extension length)
With 3 profiles – extension travel longer than the installation length.
Super over-extension (up to 200% extension length)
3 to 5 profiles – double the installation length for maximum mobility in special applications.
Robust, durable, and ready for peak performance, materials of SCHOCK® telescopic slides.
Zinc-magnesium (ZM100 or Zinc+) coated steel sheet
Technical description:
- Coating: Zinc-magnesium (e.g., 96% Zn, 3.5% Mg, 0.5% Al)
- Coating thickness: approx. 7–8 µm per side (equivalent to 50 g/m²)
- Standard: According to DIN EN 10346
- Corrosion protection class: Significantly better than conventional galvanized steel (e.g., GI Z100)
Properties:
- Excellent corrosion protection: Especially at edges and cut surfaces, thanks to passivating oxide layer
- Lower material usage possible: Due to better protective effect, a thinner coating can be used
- Long service life: Even in aggressive environmental conditions (e.g., rural, industrial, or maritime atmosphere)
- Good formability and weldability
- More environmentally friendly: Lower zinc consumption, recyclable
Stainless steel sheet in 1.4301
Material 1.4301 is an austenitic stainless steel and belongs to the chromium-nickel steel group. It is one of the most commonly used stainless steels in industrial and private applications.
Properties:
- Corrosion resistance: Very good against water, humidity, diluted acids, and many household chemicals – however, not seawater-resistant.
- Weldability: Excellent – weldable without pre- or post-treatment.
- Polishability: Very good – suitable for decorative applications.
- Magnetizability: Non-magnetic or only weakly magnetic (in annealed condition).
- Formability: Very good cold formability.
Stainless steel sheet in 316L / 1.4404
Stainless steel 316L (material number 1.4404) is an austenitic chromium-nickel-molybdenum steel with particularly high corrosion resistance. The addition of molybdenum improves resistance to chlorides, acids, and saline environments.
Properties:
- Excellent corrosion resistance, even in maritime and chemical environments
- Weldable and easily formable
- Resistant to many aggressive media (acids, alkalis, chlorides)
- Non-magnetic in annealed condition
Aluminum sheet AlMg4.5Mn (EN AW-5083)
The aluminum sheet made from AlMg4.5Mn alloy belongs to the 5000 series (aluminum-magnesium alloys) and is characterized by very good corrosion resistance, high strength, and good weldability. The addition of magnesium (approx. 4.5%) and manganese (Mn) gives the alloy excellent mechanical properties, even in welded condition.
Typical properties:
- Density: approx. 2.66 g/cm³
- Corrosion resistance: Very good – especially against seawater
- Strength: High, even after welding (higher than many other Al alloys)
- Weldability: Very good (MIG, TIG)
- Machinability: Medium – more difficult to machine due to strength
- Non-heat-treatable: Strength cannot be increased by heat treatment (only work-hardened)
