As this is a discussion page I like to raise a discussion rather than delete the content (my normal response to spam)
Possbile spam discussion
While most spam is obvious this one is almost semi related to reprap.
why it is spam: - reference of a generic product to a single supplier - no application to for repraps yet
why it could be usefull: - it might be usable as bed springs, extruder tensioners
why it is useless: - the supplier sels wholesale (prices per 1000pcs)
what this supplier should have done: - provide possible applications specific to reprap - send a sample package to core reprap developers
DIN 2093 Disc Springs
File:Http://www.xmdiscsprings.com/images/din2093-discspring.jpg Disc springs are conically-shaped, washer-type components designed to be axially loaded. We makes disc springs as per DIN 2093, the deflection for a given load is predictable and the minimum life cycle can be determined. Disc springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be used singly or in multiples stacked parallel, in series or in a combination thereof.
The advantages of disc springs compared to other types of springs include the following:
* A wide range of load/defl ection characteristics
* High load capacity with small deflection
* Space savings – high load to size ratio
* No set under design loads
* Longer fatigue life
* Inherent dampening especially with parallel stacking
* Flexibility in stack arrangement to meet your application requirements
Disc spring range:
Parts according to Din 2093 disc springs are listed into 3 groups.
Group 1 Material thickness < 1.25mm
Group 2 Material thickness 1.25 - 6.0mm
Group 3 Material thickness > 6.0 - 14mm
