Pulley on Rod with Clamp
Product Code : SCL-PL-12354
Pulley on Rod with Clamp (SKU SCL-PL-12354) is a 50 mm diameter grooved pulley mounted on a rod that fixes to the edge of a bench with a metal C-clamp. It carries a string over the table edge for Atwood-type, acceleration and friction experiments in school and college physics labs. Science Lab Supplies makes the pulley at its Saha, Ambala factory, Plot 448, HSIIDC Industrial Area, India, and ships it direct to schools, colleges, tender contractors and distributors.
Specifications
The 50 mm diameter pulley is grooved so the string tracks in one place as it runs. Its rod slides in an adjustable table clamp with a sturdy metal C-clamp base, and a clamping screw holds the pulley shaft at the chosen position on the bench edge.

Applications and Experiments for the Pulley on Rod with Clamp
The clamp pulley turns any bench edge into a pulling station: a string from a trolley or block runs over the groove to a hanging mass, so falling weight provides a steady force. It is used in Newton's-law, friction and energy experiments across Class 9–12 physics and first-year college mechanics.
- Class 9 and Class 11 laws of motion: accelerating a trolley with a hanging mass to relate force, mass and acceleration.
- Class 11 physics: finding the coefficient of friction by pulling a block along the bench with a known load.
- Class 11 practicals: Atwood-style experiments on the acceleration of connected masses.
- College mechanics labs: work done by a falling mass and conversion to kinetic energy.
Tighten the clamping screw fully before loading the string, and keep the string in line with the groove so it does not ride off the pulley.
Standard Scope of Supply
Each unit is supplied complete: the 50 mm grooved pulley on its rod, fitted to the adjustable metal C-clamp with clamping screw. String, trolleys and masses are separate items and can be added to the quotation if your laboratory needs them for the experiments listed above.
Packing, MOQ and Lead Time
You can request a quotation for a single pulley or for one on every bench in the laboratory. Each quotation confirms packing, delivery time and price for the number you give, and mass sets or trolleys from our mechanics lab equipment range can be priced with it.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Reach the sales team through the contact page, collect items in the enquiry cart, or see how tenders are handled on the lab tender page.
Frequently Asked Questions
How does the Pulley on Rod with Clamp attach to a bench?
The metal C-clamp base grips the edge of the bench, and a clamping screw holds the pulley shaft. Because the rod slides in the adjustable clamp, the pulley height can be set to suit the trolley or block.
What size is the pulley?
The pulley is 50 mm in diameter and grooved, so the string keeps a proper tracking location while it runs over the wheel during motion and friction experiments.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures these clamp pulleys in-house at its factory in Saha, Ambala, India. Buyers therefore receive pricing and delivery terms from the manufacturer itself rather than through an agent.
Can I order one pulley per student bench?
Yes. Give the number of benches and the delivery address, and the quotation will cover that quantity together with any masses, string or trolleys you add.
