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 suits secondary technology, polytechnic and TVET engineering science classes. Science Lab Supplies makes the kit itself, manufacturing it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and quoting schools, colleges, tender contractors and distributors directly.
Specifications
Specifications of the screw jack, wedge and bearing kit follow in the table. In short, the three kinds of machine element fix to the work panel and are loaded with effort and load weights to find their relative mechanical advantage and efficiency, showing why engineers choose some materials and devices over others 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, related to the sloping plane of the Inclined Plane Brass.
- Bearings: comparing materials and types under the same load, beside a single-row stainless steel Ball Bearing.
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. Questions about the kit can go through the contact page, a full class order can be listed in the enquiry cart, and tender paperwork is explained on the lab tender page.
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. With the kit, students can link this behaviour to friction and efficiency.
Is Science Lab Supplies the manufacturer or a trader?
The kit is manufactured on Science Lab Supplies premises in Saha, Ambala, India, so the company that quotes you is the maker itself rather than a dealer or agent.
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.
