RoHS compliancy

The majority of the standard products available in the ELESA catalogue are compliant with the European Directive 2002/95/CE (RoHS directive, Restriction on Hazardous Substances).

However, there are some exceptions for some products which are not yet compliant owing to technological limits in the field of research in raw materials hence not due to ELESA's direct responsibility.By clicking on each product code in the table, you can directly check the status of the product as to RoHS compliancy.

All compliant products are supplied with a label showing the RoHS symbol.

Features and applications
ELESA vibration-damping elements have been designed to damp vibrations, shocks and noises produced by moving bodies or vibrating masses which can cause:
- malfunctioning and reduction of the machine lifespan and/or of the adjacent ones
- noise
- damage to men’s health.

Technical data and guidelines for the selection of vibration-damping levelling elements
Basic data required:
- disturbing frequency: the frequency of the disturbing vibration produced by a on-duty machine. In general, it coincides with the number of rotations of the engine [rpm]
- the static load applied to every single vibration-damping element [N]
- the isolation degree required [%]
- for every type of vibration-damping element and for every size, maximum static load [N], maximum static deflection [mm] and load/deflection relation are given. The values are reported in the Main Dimensions table. For DVA.6 and DVA.7 the non-linear progress of the load/deflection relation is reported in graph 2.

How to choose the vibration-damping element:
- with reference to the nomograph (graphic 1), intersect the disturbing frequency value with the isolation degree required (each isolation degree corresponds to a line on the nomograph) and define the deflection (static deflection mm)
- the values reported in the table for maximum static load [N], static deflection [mm] and for load/deflection relation (for DVA.6 and DVA.7 see graph 2), help to identify the product that, under the given static load [N], presents the static deflection [mm] calculated at the above-mentioned point.

Example:
Application with the following features:
- 3000 rpm disturbing frequency
- static load applied on each vibration-damping element 60N
- 90% isolation required
- assembly required type DVA.1
- Graphic 1 shows that with a 3000 rpm disturbing frequency and an isolation degree of 90%, the deflection obtained is 1.0mm.
- The values reported in table, for type DVA.1, shows that the vibration-damping element which should be used is: DVA.1-10-10-M4-10.
