Line Shaft Unit
Line Shaft Unit (Product Code: SLE/PHY/232) is a base-mounted shaft and pulley unit used to show electrical energy being converted into potential energy, by winding up a weight on a cord, in school physics energy lessons. It is one of the separately available units of the Energy Transfer Kit, built on a 165 x 100 mm base with a 6 mm steel shaft and a 56 mm aluminium 'V' pulley. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Line Shaft Unit Used For?
In an energy-transfer lesson, an electrically driven unit turns the line shaft through its V pulley. The cord, fixed by the anchoring collar, winds onto the turning shaft and lifts a weight, so the electrical energy put in ends up stored as gravitational potential energy of the raised mass. Students can note the mass and the height gained to calculate that stored energy, then compare it with the electrical energy supplied to discuss efficiency and losses.
Because every unit in the Energy Transfer Kit shares the same 165 x 100 mm base, the line shaft lines up neatly beside the other units on the bench, and teachers can build different chains of energy conversion from the same set. It is a practical piece of school physics lab equipment in India for teaching energy stores and transfers.
What to Specify When Ordering
- Which other Energy Transfer Kit units you need to drive or extend the line shaft.
- The number of Line Shaft Units per lab or per student group.
- Whether a weight and cord should be quoted, as these are not listed with the unit.
OEM Manufacturer
The Line Shaft Unit is produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM (original equipment manufacturer) for its Energy Transfer Kit units. The company makes this apparatus at its own licensed factory in Saha, Ambala, Haryana, and supplies it factory-direct to schools, colleges, laboratory dealers and importers in India and international markets. If you need extra units to complete a kit, or spare parts later, ask the manufacturer directly. More about the company is on the ScienceLab profile page.

Frequently Asked Questions
What does the Line Shaft Unit demonstrate?
The Line Shaft Unit demonstrates the conversion of electrical energy into potential energy. When the shaft is driven, a cord anchored at one end winds up and lifts a weight, showing students how energy supplied electrically can be stored in a raised mass.
What are the main dimensions of the Line Shaft Unit?
The Line Shaft Unit is built on a 165 x 100 mm base, like every Energy Transfer Kit unit. It has a 6 mm steel shaft carrying a 56 mm diameter aluminium 'V' pulley at one end and a cord anchoring collar at the other.
What drives the Line Shaft Unit?
The Line Shaft Unit is driven through its 56 mm V pulley by another unit, and it is intended for showing electrical energy turning into potential energy. Tell us which drive or motor unit you plan to use via the contact page and we will confirm the best arrangement.
Are a weight and cord included with the Line Shaft Unit?
A weight and cord are not listed as part of the Line Shaft Unit. Ask us when you enquire if you would like suitable masses and cord quoted with it, so the unit is ready for the winding experiment as soon as it arrives.
Who manufactures the Line Shaft Unit?
The Line Shaft Unit is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and additional kit units are handled by the manufacturer itself.
Can other Energy Transfer Kit units be ordered with the Line Shaft Unit?
Yes. The Energy Transfer Kit is made up of separately available units, so the Line Shaft Unit can be ordered alone or together with drive, spring and motor units. List the units and quantities in your enquiry for a combined quotation.
