Spring Unit
Product Code : LSK-PL-10375
Spring Unit (SKU LSK-PL-10375) is one of the separately available units of an Energy Transfer Kit, used to show how the potential energy stored in a wound-up spring can be converted to electrical energy or used to raise a weight. It suits energy lessons in secondary school and introductory college physics. Science Lab Supplies manufactures the unit at its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area, India) and supplies schools, colleges, tender contractors and distributors without intermediaries.
Specifications
A steel shaft carries a clock spring with a free-wheel device and a winding ratchet, together with an aluminium V pulley of 56 mm diameter. The unit is supplied complete with a driving belt. Like every unit of the kit, it is built on a 165 x 100 mm base.

Applications and Experiments for the Spring Unit
The Spring Unit makes energy conversion visible: winding the spring stores potential energy, and releasing it drives the pulley. It fits the work and energy chapter of CBSE/NCERT Class 9 science and the work, energy and power chapter of Class 11 physics, as well as general science energy demonstrations.
- Class 9 science: transformation of energy from one form to another.
- Converting the potential energy of a wound-up spring into electrical energy.
- Winding a weight on a cord to show potential energy changing to kinetic energy and back.
- Class 11 physics: discussing energy conservation and losses in a real mechanism.
Standard Scope of Supply
The Spring Unit is supplied complete with its driving belt, mounted on the 165 x 100 mm base with the clock spring, free-wheel device, winding ratchet and 56 mm aluminium V pulley. Other units of the Energy Transfer Kit are available separately and can be listed on the same quotation.
Packing, MOQ and Lead Time
Quotations can be prepared for one Spring Unit or for several units across a science department. Each states packing, delivery time and price for the requested quantity, and as a science apparatus manufacturer in India we can include masses, pulleys or energy meters on the same quotation.
Being a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Get in touch via the contact page, build a list in the enquiry cart, or check the lab tender page for tender supply.
Frequently Asked Questions
What does the Spring Unit demonstrate?
It demonstrates the conversion of potential energy stored in a wound-up spring into electrical energy, and it can also wind a weight on a cord to show potential energy changing to kinetic energy and back.
Is the Spring Unit sold on its own?
Yes. It is one of the Energy Transfer Kit units that are available separately, so you can order it alone or with other units of the kit.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies builds the Spring Unit in its own factory at Saha, Ambala, India. Buyers therefore deal with the manufacturer directly, from the first quotation to dispatch.
Is a driving belt included?
Yes. The unit is supplied complete with a driving belt for the 56 mm aluminium V pulley.
