Tensile testing machines are only as reliable as the components they rely on—especially the jaws and grips that handle materials under stress. When those parts wear down, accuracy suffers, downtime increases, and safety risks go up. Yet many labs and manufacturers delay replacements until it's too late, compromising both performance and compliance.
Regular maintenance and timely tensile jaw replacements are essential to extending machine life and preserving test integrity. At Sjogren Industries, we’ve seen firsthand how small parts can have big consequences. That’s why we offer a full range of tensile testing grips and replacement jaws engineered to keep your operation running efficiently and confidently.
In any tensile testing setup, the jaws and grips do more than just hold the specimen—they ensure the validity of the entire test. Proper alignment, consistent clamping force, and minimal slippage are critical for producing repeatable, standards-compliant results. Over time, even the most rugged tensile jaws wear down from repeated use, especially when testing hard or abrasive materials. Worn grips can introduce slip, misalignment, or stress concentrations that skew your data and compromise safety.
That’s why tensile testing grips and jaws are among the most important components to monitor and maintain. Whether you're running ASTM, ISO, or internal standards, degraded jaws make accurate tensile testing much harder to achieve. At Sjogren Industries, we provide high-precision tensile jaw replacements that match or exceed OEM specifications—giving you confidence in every pull, every time.
Worn tensile jaws may not seem like a big deal—until they start ruining your results. Over time, the grip surfaces lose their bite, leading to slippage, inconsistent clamping force, and premature specimen breaks. These issues not only distort your tensile testing data but can also cause damage to the testing machine itself or trigger safety concerns in high-force wire applications.
You might notice subtle red flags at first: increased test variability, sudden drops in pass rates, or unusual failure points in your materials. But these warning signs usually indicate the jaws are past their prime. Unfortunately, many labs wait until problems become severe before addressing them.
Replacing your tensile testing grips and jaws before they fail helps you avoid downtime, wasted specimens, and unreliable results. Sjogren’s tensile jaw replacements are designed for long-term performance and easy integration with major OEM tensile testing machines—so you can swap them in and get back to work with confidence.
Not all tensile jaw replacements are created equal. At Sjogren Industries, we manufacture high-performance jaws and grips that match or exceed OEM quality—without the lead times or inflated pricing. Every part is engineered with precision tooth patterns to ensure secure, consistent clamping that protects both your specimen and your tensile testing machines.
Our tensile testing grips and jaws are built from durable, wear-resistant materials to extend service life under high-cycle testing conditions. They’re compatible with leading brands like Tinius Olsen, Instron, Satec, Forney, and United, making it easy to upgrade or replace worn components without a full system overhaul.
What sets Sjogren apart is our commitment to short lead times and responsive support. Whether you're replacing one set or updating an entire lab, our team ensures you get the right jaws—fast. With Sjogren, you're not just ordering parts; you're investing in accuracy, uptime, and long-term machine performance.
Tensile testing machines are only as reliable as the components they rely on. That’s why routine inspection of your tensile jaws and grips should be part of your lab’s maintenance schedule. Look for signs of wear like rounded teeth, slippage during testing, or inconsistent breaks in specimens—these often point to jaw degradation.
Replace worn tensile jaws before they cause downstream issues like data inaccuracies, machine strain, or costly retesting. Clean grips regularly to remove residue that could interfere with specimen contact. For labs with high testing volumes, consider keeping a spare set of tensile jaw replacements on hand to reduce downtime.
It’s also smart to verify compatibility with your tensile testing machines before ordering replacements. Sjogren’s team can help you identify the correct product quickly, minimizing disruption. With just a few preventive measures, you’ll extend machine life, improve test quality, and reduce avoidable repair costs.
