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_.
