Rotating Fatigue Machine
Product Code : LSK-MTE-10517
Rotating Fatigue Machine (SKU LSK-MTE-10517) demonstrates fatigue failure of metals under alternating stress. Based on Wohler's design, it spins a circular cantilever specimen with a load at its free end and counts the cycles until it breaks. It serves strength of materials and machine design labs in engineering degree and diploma courses. Science Lab Supplies, a scientific laboratory equipment manufacturer, produces it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, with quotations going directly to colleges, polytechnics, tender contractors and distributors.
Specifications
The Wohler-type fatigue machine is specified point by point in the table. In short, a robust main unit spins a collet-held cantilever specimen through a variable speed drive, a gimbal-mounted bearing and load arms with a sliding dead weight apply a purely vertical load, and a separate unit displays load, speed and cycles.

Applications and Experiments for the Rotating Fatigue Machine
With the machine, students can load a specimen, run it to failure and record the cycles, then repeat at other loads to build a stress against cycles (S-N) curve. It fits fatigue topics in B.Tech/B.E. mechanical strength of materials and design of machine elements practicals, and in polytechnic mechanical courses.
- Plotting an S-N curve for the supplied steel or aluminium specimens, with specimen diameters measured on a Micrometer.
- Comparing fatigue behaviour of steel and aluminium.
- Relating fatigue life to the static stress-strain behaviour recorded on the Materials Laboratory With Data Capture.
Standard Scope of Supply
Each machine comprises the main unit with guard and base storage area, the separate control and instrumentation unit, aluminium and steel specimens, and the tools to fit and remove them. Extra specimens can be quoted with the machine or ordered later.
Packing, MOQ and Lead Time
Request a quotation for one machine or for a materials lab fit-out; it gives packing, delivery time and price for that exact quantity. Spare specimens and other engineering lab equipment in India from this range can sit on the same quotation.
Registered with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. Quotes for machines and spare specimens can be requested on the contact page, staged in the enquiry cart, or arranged for a public tender through the lab tender page.
Frequently Asked Questions
What does the Rotating Fatigue Machine display?
The separate control and instrumentation unit shows the applied load, the speed or cycle rate, and the number of cycles, which freezes at the moment the specimen fails.
Does the motor stop before the specimen breaks?
No. The cut-off acts only when the specimen actually breaks, not when it is close to failure, so the recorded cycle count is the true life.
Is Science Lab Supplies the manufacturer or a trader?
This machine is produced on the Science Lab Supplies factory floor in Saha, Ambala, India; the company is its manufacturer, not a reseller, and prices it directly for your quantity.
How are users protected from the rotating parts?
A removable clear guard covers them, and its interlock switch stops the motor if the guard is taken off. Run tests under staff supervision and keep hands clear while the shaft turns.
