Pulley, Metal, Single, Parallel
Pulley, Metal, Single, Parallel (Product Code: SLE/PHY/278) is a single 50 mm metal pulley wheel mounted in a metal frame with two hooks, used as a fixed or movable pulley in introductory machines and forces experiments. It is the simplest block in the metal pulley range and is well suited to showing how a pulley changes the direction of a force before students move on to multi-wheel systems. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Single Metal Pulley Used For?
Hung from a stand as a fixed pulley, it shows that the effort equals the load but can act in a more convenient direction, which is why pulleys are used to raise flags and draw water from wells. Attached to the load as a movable pulley, with the string anchored above, it roughly halves the effort while doubling the length of string that must be pulled, giving students their first measurement of mechanical advantage with simple mechanics lab equipment.
The two hooks make the frame easy to use in either role, and the single block combines with double or triple blocks to make three-string and larger systems. Keep the wheel groove clean, check that the wheel turns freely before each lesson, and add masses gradually so the string stays in the groove.
What to Specify When Ordering
- Quantity: two per group lets students compare fixed and movable pulleys side by side.
- Double or triple pulley blocks to combine with it for larger systems.
- Masses, hangers and a spring balance.
OEM Manufacturer
ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM that manufactures this single metal pulley at its own licensed factory at Saha, Ambala, Haryana, India. Because the metal pulley range is produced by the same maker, single and double blocks can be ordered together and match one another. For extra quantities or repeat orders, ask us directly.

Frequently Asked Questions
What size is the Pulley, Metal, Single, Parallel?
The Pulley, Metal, Single, Parallel has one pulley wheel of 50 mm diameter mounted in a metal frame. The frame carries two hooks, so the pulley can be hung from a support or attached to a load, depending on the experiment.
Can the single metal pulley be used as both a fixed and a movable pulley?
Yes. The Pulley, Metal, Single, Parallel can hang from a stand as a fixed pulley to change the direction of a force, or be hooked to the load as a movable pulley, which roughly halves the effort needed to lift it.
What else is needed to use the Pulley, Metal, Single, Parallel?
To use the Pulley, Metal, Single, Parallel you need a support stand, string, a set of masses with a hanger and a spring balance for effort. These are listed separately, so include them in your enquiry if you want a single quotation.
How does the single pulley differ from double and triple pulleys?
The Pulley, Metal, Single, Parallel has one 50 mm wheel, while double and triple blocks carry two or three wheels. Combining blocks increases the number of supporting strings, and with it the mechanical advantage students can measure.
Who manufactures the Pulley, Metal, Single, Parallel?
The Pulley, Metal, Single, Parallel is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and quoted directly to schools, colleges, dealers and importers.
What should a quotation request for the single metal pulley include?
A quotation request for the Pulley, Metal, Single, Parallel should state the product code SLE/PHY/278, the number of pulleys, any other blocks or masses to include and the delivery location in India or abroad. Send it through our contact page.
