Rotational Friction Kit
Product Code : LSK-ES-10485
Rotational Friction Kit (SKU LSK-ES-10485) contains a screw jack, a wedge and a selection of bearings for studying how rotational friction affects the efficiency of common machine elements and bearing materials. Used on the Engineering Science Work Panel, it serves secondary technology, polytechnic and TVET engineering science classes. The kit is manufactured by Science Lab Supplies in its own workshop at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and schools, colleges, tender contractors and distributors buy it without a middleman.
Specifications
Three kinds of machine element are included: a screw jack, a wedge and different bearings. Students fix them to the work panel and load them with effort and load weights to find their relative mechanical advantage and efficiency, which shows why engineers prefer some materials and devices for a given job.

Applications and Experiments for the Rotational Friction Kit
The kit turns friction from an abstract loss into something students can measure. By comparing effort against load on a screw jack, a wedge and several bearings, they see where energy is lost. It matches lifting machines and friction topics in diploma applied mechanics and engineering science units in TVET courses.
- Screw jack: mechanical advantage, velocity ratio and efficiency.
- Overhaul: whether a machine runs back when effort is removed.
- Wedge: effort needed to lift a load and friction losses.
- Bearings: comparing materials and types under the same load.
Overhaul is a useful safety idea: a screw jack that does not overhaul holds its load when the effort is released, which is why efficiency and friction matter in lifting devices.
Standard Scope of Supply
The kit supplies the screw jack, the wedge and the different bearings. It fits the Engineering Science Work Panel, a separate item, and belongs to a series of kits whose parts can be combined; effort and load weights or other ancillaries are listed on the quotation if required.
Packing, MOQ and Lead Time
Quotes are available for one kit or a full class set. Each quote sets out the packing, delivery time and price for the number you request, and other engineering lab equipment in India from the Engineering Science series can be listed with it.
Holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Use the contact page to ask a question, the enquiry cart to list items, or the lab tender page for tender enquiries.
Frequently Asked Questions
What does the Rotational Friction Kit include?
A screw jack, a wedge and different bearings, all designed to be mounted on the Engineering Science Work Panel for mechanical advantage and efficiency tests.
What does overhaul mean in these experiments?
Overhaul describes a machine that runs backwards under its load once the effort is removed. Students use the kit to link this behaviour to friction and efficiency.
Is Science Lab Supplies the manufacturer or a trader?
The manufacturer. Science Lab Supplies makes the kit on its own premises in Saha, Ambala, India, and handles quotations from there.
Can it be included in laboratory equipment tenders in India?
Yes. Share the quantity, delivery site and tender specification, and the kit can be quoted item by item with the panel and related kits.
