Profile damper TA 47-20 diameter 45mm thread M12
Material: Co-Polyester Elastomer. The profile damper TA are maintenance-free, self-contained damping elements. Due to the degressive damping characteristics it provides a very high energy absorption at the beginning of the stroke. The excellent temperature characteristic of the material provides consistent damping performance over a temperature range of -40°C to +90°C. The low installed weight, the economic price and the long operating life of up to 1 million cycles makes this an attractive alternative to hydraulic end position damping, if the moving mass does not need to stop in an exact datum position and it is not necessary to absorb 100% of the incoming energy. The life cycle is up to 20 times longer than for urethene dampers and up to ten times longer than for rubber springs. Environment: Resistant to oil, grease seawater and to microbe or chemical attack. Excellent UV and ozone resistance. Material does not absorb water or swell. Dynamic Force Range: 870 N to 90,000 N. Temperature Range: -40°C to +90°C. Energy Absorption: 58% to 73%. Material Hardness: Shore 55D. Mounting: in any position. Impact Velocity range: up to max. 5 m/s Mounting Bolt Torque: M3: 1 Nm. M4: 2 Nm. M5: 4 Nm. M6: 6 Nm. M8: 20 Nm. M12: 50 Nm. M16: 120 Nm. On request: special strokes, characteristics, spring rates, sizes and materials.
