Miniature shock absorbers

Miniature shock absorbers

ACE Controls miniature shock absorbers are designed to effectively absorb kinetic energy across a wide range of environments and applications. They are used in everything from moving machine parts, cylinders, and linear units to robots and rotating or oscillating loads. By reducing the load at end positions, the shock absorbers protect equipment and extend component life. They are also ideal for increasing machine cycle speeds, as they allow for faster movement without compromising precision or safety. In doing so, they help improve efficiency, boost productivity, and ensure reliable operation. Thanks to their innovative design, ACE shock absorbers have a service life of up to 25 million cycles. In addition, ACE shock absorbers are maintenance-free and available in both self-compensating and adjustable versions—making installation and operation even easier.

Increased production speed and quality

By absorbing kinetic energy at high speeds, miniature shock absorbers enable faster cycle times without sacrificing safety or accuracy. This means that the machine doesn’t need to slow down before end positions or stops, optimizing the production flow. In addition, the risk of quality issues caused by impacts or transmitted vibrations is significantly reduced.

Protection from shocks and vibrations

Miniature shock absorbers serve as an important safety component in machines and production lines. By effectively reducing shocks and vibrations, they minimize component wear, improve the working environment by lowering noise levels, and reduce the risk of personal injury during unexpected movements or accidents.

Long service life – even in demanding environments

ACE Controls shock absorbers are made from high-strength alloy steel and are available in stainless steel versions, making them ideal for harsh environments such as marine applications or the food industry. A specially developed sealing technology enhances safety and ensures long-lasting performance. Some models feature a hermetic seal and a rolling diaphragm instead of conventional sealing, increasing the service life from 1 up to 25 million cycles.

Efficient energy absorption

ACE Controls shock absorbers are specifically designed to manage and control kinetic energy in dynamic systems. They adapt to various types of motion—linear, rotary, or oscillating—providing precise damping that optimizes machine performance. Typical applications include industrial robots, CNC machines, conveyors, and packaging machines, across sectors such as the food industry, pharmaceutical industry, packaging, automotive manufacturing, and general industrial production.

Flexible mounting and accessories

Installation is straightforward using various mounting options such as flanges, clamps, or clevis mounts. Some models can also be directly integrated into pneumatic cylinders. Accessories such as rod protectors, side-load adapters, and stop collars with position sensors further enhance functionality. ACE’s Airbleed solution ensures a continuous air flow that keeps the piston rod free from contaminants, improving reliability in dirty or humid environments.

Support with selection and sizing
