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 hung 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. As a scientific laboratory equipment manufacturer, Science Lab Supplies makes the machine at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India and supplies colleges, schools, tender contractors and distributors directly.
Specifications
The machine has a robust main unit and a separate control and instrumentation unit. A variable speed drive raises the cycle rate gradually, a collet chuck grips the specimen concentrically, and a gimbal-mounted bearing with load arms, load cell and sliding dead weight applies a purely vertical load. A switch stops the motor when the specimen breaks.

Applications and Experiments for the Rotating Fatigue Machine
Students 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. The machine 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.
- Comparing fatigue behaviour of steel and aluminium.
Specimens are shaped so peak stress falls at their midpoint, giving a definite failure point away from the chuck. Because the cycle count freezes when the specimen breaks, long runs need no one standing by.
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. Start a conversation on the contact page, save the machine to the enquiry cart, or use the lab tender page for formal bids.
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?
Science Lab Supplies is the manufacturer; this machine comes from its own factory in Saha, Ambala, India, and the factory prepares every quotation.
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.
