Manufacturer: Getzner Spring Solutions

wibroizolator sprezynowy ISOTOP SD Reinicke

 Design

The Isotop® SD spring vibro-isolators consist of two plate bases with an internal M10 thread and a cylindrical coil spring (according to the DIN EN 13906-1:2001 norm. Tolerance values according to DIN 20950). The plate bases are permanently fixed to the coil spring with a special two-component compound.
Depending on the needs, SD vibro-isolators could be attached to the base:
- directly with a screw with M10 thread,
- by use the galvanized metal base plate, type FP 1-9.
If leveling of the equipment is required, use adjusting screws type NV 1-9.

The vibro-isolators can be protected against corrosion through either galvanisation or cataphoretic coating (KTL) in RAL 9005 colour paint (jet black). Other paint colours are also available.
