Ball Bearings in the Wheel Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12561
Jlab Export is a leading Ball Bearings in the Wheel Manufacturer,and suppliers in India
Ball Bearings in the Wheel (code EL-PL-12561) is a single-row radial ball bearing with a 25 mm inner diameter, used to show how a ring of balls lets a wheel turn on its axle with rolling rather than sliding friction. Students can spin it by hand and compare it with a wheel turning on a bare axle. JLab makes the bearing in Ambala, India.

How a Radial Bearing Works
The balls run in grooves between an inner ring, which fits the 25 mm shaft, and an outer ring, which fits the wheel hub. As the wheel turns the balls roll instead of rubbing, so the resistance is far lower than for a hub sliding on its axle. Radial means the bearing mainly carries loads at right angles to the shaft, such as the weight resting on a wheel.
A Spin-Down Test
Hold the inner ring still, spin the outer ring with a finger and time how long it keeps turning. Repeating the test after a drop of light oil shows how lubrication changes rolling friction.
