Springs Steel Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-5756
Jlab Export is a leading Springs Steel Manufacturer,and suppliers in India
Springs Steel (code EL-SLE-5756) is a steel spring listed at 30 cm with a 6 mm diameter that stretches 15 cm under a 250 g load, used for Hooke’s law, spring constant and spring–mass oscillation experiments in school and college physics practicals. The generous extension gives readings that are easy to take with an ordinary metre scale. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Springs?
| Model | What is supplied | Listed details |
|---|---|---|
| This spring (EL-SLE-5756) | One steel spring | 30 cm, 6 mm diameter; stretches 15 cm with 250 g |
| Springs Set of 5 Hooke’s Law | Five springs with different spring constants | Pre-stress removed; built-in ring to hang, hook for weights and a red indicator |
| Set of Springs | Assortment of compression and extension springs | Supplied in a wooden box |
Choose this spring when each group needs one soft steel spring with a large, easily read extension; the five-spring set lets students compare different spring constants, and the boxed assortment suits project and workshop use.
What Is the Steel Spring Used For?
Hang the spring from a rigid support, add slotted masses in equal steps and measure the extension each time: within the elastic limit the extension is proportional to the load, which is Hooke’s law, and the slope of the load–extension graph gives the spring constant. This is the class 11 physics practical on the force constant of a helical spring, and the same spring with a mass on the end oscillates up and down, so students can time the oscillations and see how the period changes with the mass for simple harmonic motion.
Add masses gently rather than dropping them on, read the pointer or the bottom of the load at eye level against a vertical scale, and ask JLab before loading the spring well beyond the 250 g listed, as stretching it past its elastic limit leaves it permanently longer. Store the spring dry to prevent rust.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- End fittings — confirm whether you need a hook, ring or pointer, as this listing does not state them.
- Masses and hangers — add slotted masses and weight hangers to the same enquiry.
Frequently Asked Questions
How far does the spring stretch?
It is listed as stretching 15 cm with a 250 g load, which gives clear, easily measured extensions in school practicals.
What size is the spring?
The listing gives 30 cm and a 6 mm diameter. Confirm in your enquiry if you need the free length or wire gauge for a particular set-up.
Can it be used to find a spring constant?
Yes. Load it in equal steps, plot load against extension and take the slope; keep the loads within the elastic limit so the graph stays a straight line.
How does it differ from the Springs Set of 5 Hooke’s Law?
This is a single steel spring with a large extension. The set has five springs with different spring constants, pre-stress removed, and a built-in ring, hook and red indicator on each.
Are masses or a stand included?
No, the listing covers the spring. Slotted masses and weight hangers are separate items, linked below.
Who manufactures this spring?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a school physics apparatus manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The springs are made in JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers order them factory-direct; every spring is checked by eye before packing, and repeat orders come from the same manufacturer. JLab is registered with GSTIN 06AADCJ9848D1ZE and holds Legal Entity Identifier 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — for example the Netherlands in Western Europe, Belize in Central America and the Caribbean, Italy in Southern Europe, Sri Lanka in South Asia and Thailand in Southeast Asia. Tender buyers can see the JLab lab tenders page.
Masses and Force Measurement
- Masses — a hanger with nine slotted 10 g masses for loading the spring in steps.
- Newton Weight Hangers — steel hangers in a range of sizes, each with a rounded newton value.
- Spring Balance — a calibrated newton meter that applies the same spring principle.
