DAMPER, HEAVY-DUTY Description: The co-polyester elastomer dampers, heavy-duty, are used as holddown dampers in the automotive and white goods industry. Increasing return stroke speeds and the related stresses on screws and bolts in moveable, suspended tool parts are absorbed by the hold-down dampers. Reduced noise emission is a further additional positive sideeffect. Benefits: - High absorption of force and energy - Slight settlement - Energy absorption between 5 Nm and 269 Nm - Long service life and high level of operating safety - Noise reduction - High degree of effectiveness Material: Co-Polyester-Elastomer Technical data: Surroundings: Resistant to microbes, seawater, chemicals. No absorption of water and no swelling. Grease and oil resistant. Approved temperature range: -40°C to +90°C (-40°F to +194°F) Note: Socket cap screw 2192.12. see Section C Spacer tube 244.9. see Section F Washer 244.10. see Section F Mounting example 2450.20_.
