Vibration Of Spiral Spring Apparatus
Vibration Of Spiral Spring Apparatus (Product Code: SLE/MCE/32) is a wall-mounted torsional oscillator used to study the stiffness and free vibration of a flat spiral spring in theory of machines and mechanical engineering laboratories. Its spring has a listed stiffness of 238 Nmm and a 10 x 1 mm cross-section, and two levers with sliding weights let students change the rotating mass while an integrated 360° scale reads the deflection. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Spiral Spring Vibration Apparatus Used For?
The practical runs in two stages. In the static stage, the metallic rod with its end masses applies a moment that turns the shaft against the spiral spring, and the angle scale shows the resulting deflection, so students can calculate the spring stiffness and read how far the spring was deflected initially. In the dynamic stage the rod is released, the spring-mass system oscillates freely, and the timed period is compared with the value predicted from stiffness and moment of inertia.
Sliding the weights along the two levers changes the moment of inertia without changing the spring, so one unit produces a full series of frequency readings for a graph. The ball-bearing axis keeps friction low, helping the oscillations last long enough to time several cycles. Fix the anodised aluminium plate firmly to a solid wall at a comfortable reading height; it is compact engineering lab equipment for vibration and SHM practicals in India and abroad.
What to Specify When Ordering
- Number of units, for example one per bench or student group
- Wall space for each 200 x 250 mm base plate
- A stopwatch or timer for the oscillation readings, if your laboratory does not already have one
OEM Manufacturer
ScienceLab is the OEM for this apparatus. Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, so it reaches buyers factory-direct rather than through a trading chain.
Technical colleges, TVET institutes, dealers and importers get quotations and technical answers from the source, and requests for replacement levers or weights on existing units go straight to the maker — just ask us. Read about the company on the ScienceLab profile page.

Frequently Asked Questions
What is the spring stiffness of the Vibration Of Spiral Spring Apparatus?
The spiral spring of the Vibration Of Spiral Spring Apparatus has a listed stiffness of c = 238 Nmm, a 10 x 1 mm cross-section and an effective length of approximately 800 mm, with an inside radius of 10 mm and an outside radius of 50 mm.
How is deflection read on the Vibration Of Spiral Spring Apparatus?
Deflection on the Vibration Of Spiral Spring Apparatus is read on an integrated angle measuring scale mounted on the axis. The scale covers 360° with a resolution of 1°, and it also shows how far the spring was deflected initially.
How is the Vibration Of Spiral Spring Apparatus installed?
The Vibration Of Spiral Spring Apparatus is built on a wall mounting plate made of anodised aluminium, with a base plate of 200 x 250 mm (width x height). Fix it to a solid wall at eye level so students can read the angle scale comfortably.
Can students change the oscillating mass on the Vibration Of Spiral Spring Apparatus?
Yes. The Vibration Of Spiral Spring Apparatus has two levers with sliding weights, so students can move the weights to change the moment of inertia and record how the natural frequency of the spring system changes with each setting.
Who manufactures the Vibration Of Spiral Spring Apparatus?
The Vibration Of Spiral Spring Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. It is supplied factory-direct to institutions, dealers and importers.
