Extreme temperature and high cycle applications

Energy capacity 16,551 in-lbs/cycle
Stroke 1.91 inch

Greater application range: just like all MAGNUM types from the product family MC33 to MC64, the HT (high temperature) industrial shock absorbers are also made from one solid piece. They use special seals and fluids. This means that these versions can even be used at extreme temperatures of 32°F to +302°F (0 °C to 150 °C) in order to safely and reliably damp masses and absorb 100% of the kinetic energy.

These ready-to-install machine elements are recommended even under the most unfavorable conditions. Additional benefits are their robust, innovative sealing technology, high energy absorption in a compact design, fixed positive stop and a wide damping range. Self-compensating shock absorbers react to changing energy conditions, without adjustment.
