The Tubus range of co-polyester elastomer profile buffers offers a low cost damping solution where a moving mass does not need to be decelerated to an exact datum position and it is not necessary to absorb 100% of the incoming energy. Their life expectancy, of up to one million cycles, is up to 20 times longer than urethane buffers, ten times longer than rubber buffers and up to five times longer than steel springs.
Tubus buffers have an operating temperature between -40°C to +90°C, and are resistant to grease, oil, petroleum, chemical attack and seawater. They also have excellent UV and ozone resistance. Five models are available - TA, TS, TR, TRL and TC - offering different stopping characteristics and energy capacities ranging from 2Nm up to 12,720Nm per cycle. The application illustrated here shows a Tubus TA 22-10 being used as an emergency stop on a plasma cutting machine.
