Elastomer springs S55 - 90 Shore A - DIN 9835 / ISO 10069
The S55 elastomer springs are use in press tools to hold the sheet during the lowering phase.
Specifications
Material : 90 Shore A - Urelast
Standard : NF ISO 10069 / DIN 9835
Dimensions :
- Diameter : from 16 to 125mm
- Length : from 12 to 160mm
Load : From 160 to 15000 daN depending on the diameter and the length
Resistance : Elastomer springs do not break. Very resistant to abrasion
Preload : The preload must be greater than the compression settlement (6-8%)
Maximum compression : 30% of the total length
Modulus of elasticity : 35 N/mm^2 at room temperature
Operating temperature : -20°C to +80°C
Benefits :
- Easy to install
- Does not break or generate waste, preventing damage to the tool.
- Reduced noise
- Maintenance-free
- Able to withstand heavy loads
Tolérance :
- Depending on the diameter ±0,25 to ±1,3mm
- Depending on the length ±0,4 to ±2mm
Recommendation for use :
Mounting : The spring is individually fitted between the stripper plate and the top plate thanks to shoulder screw or guiding shafts and washers. The elastomer spring expands when compressed, so a sufficiently large housing is required.
Use conditions :The preload is mandatory and ensures immediate force.
Storage : Store out of direct sunlight and in an environment where humidity does not exceed 65%.
To order you need to indicate :
- The diameter
- The lenght
Example : S55.032.050
