  • Introducing Ace Shock Absorbers

    Ace Shock AbsorbersAce Shock Absorbers

    ACE is the World leader in deceleration technology. Ace shock absorbers perform a range of functions including preventing impact damage, improving product performance, providing longer life and reliability, and decelerating loads, enabling mechanical devices to operate smoothly and efficiently. Ace Shock Absorbers encompass new innovations including the award winning SC2 Heavyweight Series and the adjustable and self-compensating industrial shock absorber models. This can benefit multiple industries including steel, material handling, robotics, automotive, medical and many more.  ACE Shock absorbers are made in the USA and every shock is tested 100% before shipping.

    ACE Miniature Shock Absorbers are self-contained hydraulic units. The MC 5 to MC 75 model range has a very short overall length and low return force. Its small size allows for high energy absorption in confined spaces, while the wide effective weight ranges accommodate a variety of load conditions. With threaded outer bodies and multiple accessories, MC models can be mounted in numerous configurations.

    ACE’s award winning SC2 300 and SC2 650 Heavyweight Series Shock Absorbers deliver up to 950% of the effective weight capacity and 280% of the energy absorption capability of standard models. These durable units are ideal for decelerating heavy weights moving at low velocities. The Heavyweight Series design combines the piston and the inner tube into a single component, the piston tube. It acts as both the pressure creating and pressure controlling device.  ACE’s SC2 300 and SC2 650 Heavyweight Series Shock Absorbers offer expanded effective weight ranges and dramatic increases in energy absorption capability, for handling a wider range of applications.  These revolutionary shock absorbers provide dual performance benefits. They offer soft contact deceleration where initial impact reaction forces are very low with the advantages of self compensation to cope with changing input energy conditions without adjustment.

    ACE MA Series miniature shock absorbers offer a compact design with true linear deceleration, and are adjustable over a wide range of conditions. If your preference is a fully adjustable shock absorber rather than a self-compensating model on your application, then the MA Series provides a directly interchangeable alternative.

  • Uses for Firestone bellows W01-358-0981

    Firestone W01-358-0981

    Firestone W01-358-0981 Bellows

    The W01-358-0981 style 28 bellows-only is a “Super Duty Airstroke” which is a high temperature, oil resistant part made of Firestone's Epichlorohydrin elastomer.  Technigram 111 applies to this component and includes complete details about the advantages and limitations of this special elastomer.  The fact that this part is a bellows-only means that the flanges for attaching it to the machine are part of the machine and not included in the scope-of-supply with this part.

    A great application for Epichlorohydrin would be on a paper machine controlling the nip pressure between two rolls in an atmosphere of 93°C. In this case, the Airstroke is at constant height and pressure, probably 99% of the time. (Except when one roll is backed off for threading of the material.)  Epichlorohydrin will far outlast our standard elastomer in this instance, and, therefore, is well worth the extra cost.  Download the Firestone Techinigram here or download the bellows spec sheet for part number W01-358-0981 here.

  • Quick Exhaust Valve Spotlight

    Quick Exhaust Valve

    Quick Exhaust ValveThese Super quick exhaust valves feature a special molded shuttle designed especially for quick response, high flow and long cycle life.  The universal design of the Quick Exhaust Valve allows it to be used as a valve, a shuttle valve, or plug the exhaust port and use it as a check valve.  With the molded shuttle design, the Super Quick Exhaust Valve have an operating range as low as 1 psi to 150 psi.

    These valves are used across all industries wherever fast pneumatic cylinder stroking is required.  Some industries where quick exhaust valves are used include: wood/lumber, tire, food packaging, paper finishing, material handling & conveying, stamping and die-cutting.

    These valves are applied to allow cylinders to exhaust air at the cylinder port instead of having the air travel all the way back through the supply tubing to the directional valve to exhaust there.  These valves can also be used as a shuttle valve, the “or” logic function, automatically selecting the higher of two input pressures to produce an output.

    We also offer 316 stainless and electrically operated (including hazardous locations) quick exhaust valves from Versa.

  • Industrial Air Spring Failure Causes

    When applied and maintained properly, industrial air springs can last for long amounts of time, trouble-free of service.  Most failures are caused by a lack of suspension maintenance or improper application. Common failures are caused by misalignments, loose girdle hoops, abrasions, air spring overextension and the bottoming out of air springs.  Download Firestone's guide to common air spring failures that are usually not covered by warranty.
