A metal insert keeps the polymer from
bending over during impact and allows it to collapse upon itself in a
precisely controlled manner.
Leadscrew and ballscrew drives and other critical components need fail-safe protection in emergency stop and axis over-run conditions. As an alternative to rubber bumpers and hydraulic shocks, the One-Shot Emergency Shock Absorber costs only a few dollars per use. Upon impact, the device converts kinetic energy into heat as it deforms. The company uses different high-grade polymer combinations to meet various load capacities ranging from approximately 16 to 4,000 inch-lbs.
Available with thread diameters of 3/8 and 1.25-inches, the corrosion-resistant design offers a minimum service life of 10 years, and handles -13 to 122F temperature operation.
