Ball Bearing
Product Code : SCL-PL-12359
Ball Bearing (SKU SCL-PL-12359) is a single-row stainless steel ball bearing with a 25 mm inner diameter. Bearings of this kind are used in precision instruments, low-noise motors, automobiles, motorcycles and machinery, and in a physics lab one shows students how rolling elements reduce friction. It also serves as a real component for mechanical and automotive training. Science Lab Supplies supplies the bearing from Ambala, India to schools, colleges, ITIs, training institutes, tender contractors and distributors.
Specifications
This is a single-row ball bearing made of stainless steel with an inner diameter of 25 mm. A single ring of balls runs between the inner and outer races, turning sliding friction into rolling friction, which is the principle behind its use in motors, vehicles and precision instruments.

Applications and Experiments for the Ball Bearing
In teaching, the bearing is a hands-on example of how rolling reduces friction compared with sliding. Students can spin it, feel the smooth motion and link it to wheels, fans and motors. In technical training it is used to identify bearing types and to practise fitting and removal on shafts.
- Class 8 science (friction): showing how ball bearings reduce friction in machines.
- Class 11 physics: discussing rolling versus sliding friction and why machines use bearings.
- ITI Fitter and Mechanic Motor Vehicle trades: identifying single-row ball bearings and practising fitting on a 25 mm shaft.
- Diploma mechanical engineering: machine elements and bearing selection studies.
Standard Scope of Supply
The Ball Bearing is supplied as a single unit as described above: one single-row stainless steel bearing with a 25 mm inner diameter. If you need several bearings for a class or workshop, state the quantity and it will be shown on the quotation.
Packing, MOQ and Lead Time
Ask for one bearing for a demonstration or a batch for a workshop class. The quotation you receive sets out packing, delivery time and price for that quantity, and friction apparatus or other items from Science Lab Supplies, a physics instruments supplier in India, can be added.
With its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Use the contact page for questions, the enquiry cart for a product list, and the lab tender page for tender procedures.
Frequently Asked Questions
What size is the Ball Bearing?
It has an inner diameter of 25 mm and is a single-row design made of stainless steel. For outer diameter or width, ask through the contact page and the details will be confirmed with your quotation.
How is a ball bearing used in a physics lesson?
It demonstrates rolling friction: balls rolling between two rings let a shaft turn with far less resistance than sliding surfaces, which is why bearings are fitted in fans, wheels and motors.
Who supplies the Ball Bearing?
Science Lab Supplies supplies it from its base in Ambala, India. Schools, ITIs and distributors can buy it directly, either on its own or together with other physics and workshop items.
Where are such bearings used outside the lab?
Single-row ball bearings like this one are used in precision instruments, low-noise motors, automobiles, motorcycles, general machinery and other industrial equipment, wherever a shaft has to turn smoothly with little friction.
