General Characteristics:
MK2.0 pads have been specially designed for the discontinuous soft mounting of rail on concrete using chairs and rail fixing clips.
MK2.0 pads:
• eliminate the load concentrations at the edge of the chairplate :
- their chamfered edges reduce the stress concentrations;
- pressures under the chair are reduced;
- the concrete is protected from cracking.
• reduce rail and chair wear :
- absorb uneven surfaces;
- improve contact between rail and chair.
• are manufactured in thermoplastic elastomer and feature lugs to prevent longitudinal slippage.
• are specially resistant to wear, shear, crushing, oils, greases, ozone and oxygen, as well as ultra-violet rays.
Material Characteristics:
• Composition : EVA copolymer.
• Shore hardness : 95 A (DIN 53505).
• Tensile strength : 12.5 N/mm2 minimum (DIN 53455).
• Elongation : 250 % minimum (DIN 53455).
• Working stress in compression : - up to 50°C : 20 N/mm2.
- up to 70°C : 15 N/mm2.
• Service temperature : from -25°C up to +75°C.
For
other temperatures, please consult us.
Designation and Dimensions:
Lb
: dimension of the chair in the rail axis. Standard lengths are : 110, 160 or
220 mm.
L1 : reduced width, always 5 to 8 mm less than the rail foot width (F).
Ex. : for mounting a GX42 rail (foot width : F = 131.8 mm) on 160 mm-long chairs :
MK2.0
- 160B x 125.
Application for small size rails:
For
small size rails, when fastened with clips type 21/020 or 51/015, MK2.0-type
pad - thickness 4 mm, instead of 7 mm - must be used.
