Why funnel is used for dropping the ball bearing
A funnel is used to separate an insoluble solid from a liquid.
A funnel is a chimney used for pouring liquids into bottels. Normally made up of plastic.
A Büchner funnel is adequate.
In the laboratory the funnel is used for filtrations.
A funnel support is used to place a funnel accurately into a container or beaker or maybe even a flask in order to concentrate the flow of liquid into the container which happens through the funnel
The funnel slows down the ball-bearing to almost zero acceleration. This gives a more accurate figure of the substance's viscosity.
The type of laboratory glassware that is used to transfer fluids is a dropping funnel. To allow the flow of the fluid to be controlled, they are fitted with a stopcock.
Turbochargers turn too fast for ball bearings. Sleeve bearings are typically used in this application.
Ball bearings
Gravity
ball type
Ceramic ball bearings are used for reducing frictional rotation, and to support radial and axial loads. It helps any application looking to have higher RPM.
Ball & Roller Bearings both belongs to the category of radial contact bearings.In case of ball bearings spherical balls are used however in case of roller bearings cylindrical rollers are used.due to balls used in ball bearings there is a point contact is made whether it is line contact in roller.
i think its either iron or steal
Generally, a ball bearing is used when speed is important; a roller bearing is used more often when load is most important.
in machineare parts
INA Bearings make a wide range of ball bearings and their inserts. These are used in a wide range of products, though they are best known for their use in skateboards.
