Trundle Wheel
Trundle Wheel (Product Code: SLE/ME/30) is a wheeled distance-measuring tool used to measure long distances on the ground and to demonstrate the relationship between circumference and diameter in school maths and physics lessons. Its wheel circumference measures one metre, its scale is graduated in 1 cm divisions, and an audible, non-wearing clicker sounds with each 1 m revolution in either direction. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Trundle Wheel Used For?
Students walk the wheel along a corridor, playground or sports field and count the clicks, each one a metre, then read the leftover part-metre from the 1 cm scale at the finish. It is the practical way to measure a running track for speed experiments, map the school grounds in geography, or check how good pupils are at estimating distance, which makes it useful school physics lab equipment as well as a maths tool.
In maths, the wheel shows the circumference formula in action: measure its diameter with a ruler, divide the one-metre circumference by it and the answer comes out close to pi. For accurate readings, set the wheel's starting point on the start line, keep the handle upright and walk steadily in a straight line.
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM of this trundle wheel, producing it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, education departments, dealers and importers buy it factory-direct, and questions about spare parts are answered by the manufacturer, so just ask us. For institutional vendor registration, the company's GSTIN is 06AAECJ8618A1ZT and its LEI is 3358004HRD1JIVXKYX49. See the company profile for more.
Related Measuring Equipment
Items used with a trundle wheel in outdoor measuring and motion lessons:
- Windup Meter Tapes — lay out a fixed line such as a track or transect.
- Stopwatch, Digital — times runners over the measured distance to work out speed.
- Metersticks — for shorter measurements and checking the wheel's diameter.
- Fiberglass Tape Measure — measures the wheel's rim to confirm the circumference.
The full Measuring category includes rulers, tapes, timers and thermometers.
Frequently Asked Questions
How does the Trundle Wheel measure distance?
The Trundle Wheel (SLE/ME/30) has a circumference of one metre, so each full revolution covers one metre and triggers an audible click. Count the clicks while walking, then read any remaining part-metre from the scale graduated in 1 cm divisions.
Does the Trundle Wheel click in both directions?
Yes. The Trundle Wheel's audible, non-wearing clicking device is activated with each 1 m revolution in either direction, so rolling backwards is heard too, and students can correct an overshoot by subtracting the extra clicks.
Will the Trundle Wheel slip on smooth floors?
The wheel edges of the Trundle Wheel are designed to grip smooth surfaces and prevent slippage as it rolls. That keeps readings dependable on corridors, halls and hard courts as well as on outdoor paths and playgrounds.
How is the Trundle Wheel used to teach circumference and diameter?
Students measure the Trundle Wheel's diameter with a ruler and compare it with its one-metre circumference; the ratio comes out close to pi. It links a real object to the formula for the circumference of a circle.
Who manufactures the Trundle Wheel?
The Trundle Wheel is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers in India and international markets.
What does a Trundle Wheel quotation need?
For a Trundle Wheel quotation, give the number of wheels, often one per group for outdoor lessons, the delivery location and any other items such as tapes or stopwatches for the same order. The quotation comes directly from the manufacturer.
