Overview
Rubber and elastomer components are everywhere — seals, O-rings, gaskets, tyres, shock mounts and vibration dampers — and their performance depends on how they behave under repeated loading and over time. Fatigue life, tensile strength, elongation, hardness, ageing and compression set are the key properties that determine whether a rubber part can survive the demands of real-world service.
CHENJI offers a practical range of rubber testing solutions, from rubber fatigue testing machines to electronic universal tensile testers and hardness testers. Our equipment helps rubber, tyre, sealing, vibration-isolation and elastomer manufacturers, as well as materials research and quality-control laboratories, verify incoming material and finished part quality with reliable, repeatable data.

Rubber Fatigue Testing Machine
Our Rubber Fatigue Testing Machine is the anchor solution for determining the fatigue life and flexing resistance of rubber materials, rubber-to-metal bonded samples and vulcanized rubber specimens under repeated alternating tensile, compressive or tension-compression loading at room and service temperature. It applies controlled cyclic loading to rubber dumb-bell or cylindrical test specimens and automatically records the number of cycles, stopping at a preset count for reliable, repeatable fatigue-life and crack-initiation evaluation.
- Max. test force: 5 / 10 / 20 kN (series)
- Test frequency: 1-5 Hz (low-cycle 0-3 Hz adjustable)
- Max. amplitude: ±25 mm (stroke 0-50 mm adjustable)
- Two test stations for higher throughput
- Auto counting, stops at preset cycles
- Standard: GB/T 1688, ISO 6943
Supporting Rubber Testing Equipment
WDW series Electronic Universal Tensile Testing Machines — Suitable for tensile, compression and bending tests of rubber, plastic, metal, steel, alloy, electrical wire and cable, composite and other materials. The WDW-10 (10 kN) and related WDW models give you accurate tensile strength and elongation measurement for rubber dumb-bell samples and finished elastomer parts.
Hardness Testers — For elastomer and cured-rubber hardness evaluation, CHENJI hardness testers such as the HVS-1000 Digital Micro Vickers Hardness Tester and the HB-3000C Touch Screen Brinell Hardness Tester cover a wide measuring range for soft to metallic materials.
Digital Izod / Charpy Impact Tester — Our high-precision digital Izod/Charpy combined impact tester (1 J – 22 J) evaluates impact toughness of non-metallic materials used alongside rubber products.
Industries We Serve
Industries that specify rubber testing include sealing and gasket manufacturers, O-ring and profile producers, tyre and retreading plants, vibration-isolation and shock-mount suppliers, automotive rubber-part makers, and materials research and QC laboratories.
Frequently Asked Questions
How do you run a rubber fatigue test?
Mount a rubber dumb-bell or cylindrical specimen on the Rubber Fatigue Testing Machine, set the test frequency (1-5 Hz, with low-cycle 0-3 Hz adjustable), amplitude (up to ±25 mm) and target cycle count, then start the machine. The system applies controlled alternating tensile/compressive loading and stops automatically when the preset cycle count is reached, recording fatigue life and crack-initiation behavior.
Which machine measures rubber tensile strength and elongation?
Use a WDW series electronic universal testing machine. For example, the WDW-10 (10 kN) performs tensile, compression and bending tests on rubber and elastomer samples, and the WDW range supports ISO 37 / ASTM D412 style tensile tests when paired with the correct rubber grips.
Do you offer hardness testing for rubber?
Yes. CHENJI hardness testers including Vickers (HVS-1000), Brinell (HB-3000C) and Rockwell models cover the hardness range relevant to cured elastomers and soft composites, complementing Shore-type measurement on finished parts.
What standards does your rubber fatigue machine support?
The Rubber Fatigue Testing Machine complies with GB/T 1688 and ISO 6943 for the flexing (flexing fatigue) of rubber and vulcanized rubber samples, and supports both dumb-bell and cylindrical specimen forms.
Which industries use rubber testing machines?
Rubber, tyre, sealing, vibration-isolation and elastomer manufacturing industries, plus material research and quality-control laboratories that need to verify fatigue life, tensile strength, hardness and impact toughness of rubber and rubber-to-metal parts.
