Ball bearing

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.


The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.


Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.

    The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.Angular contact ball bearings can bear both radial and axial loads.It can work at high speed.The larger the contact Angle, the higher the axial bearing capacity.The contact Angle is the Angle between the contact point line of the ball and the racewayin the radial plane and the vertical line of the bearing axis.High precision and high speedbearings usually have a 15 degree contact Angle.The contact Angle increases under theaction of axial force Single row angular contact ball bearings: machine tool spindle, high frequency motor, combustion turbine, centrifugal separator, arc welding machine double row angular contact ball bearings: oil pump, roots blower, air compressor, all kinds of transmission,fuel injection pump, printing machinery, extraction equipment and so on.ZHEJIANG WAXING ELECTROMECHANICAL CO.LTD.

    The Spherical ball bearing has two structures: a cylindrical hole and a conical hollow. Thecharacteristic is that the outer ring raceway is spherical and has self-aligning property, whichcan compensate for the error caused by the different heart and shaft deflection to make thespherical ball bearing, but the inner and outer rings can not read more than-3 degrees,The conical inner bore has a taper of 1:12 or 1:30. To enhance the lubrication of the bearing,an annular oil groove and three oil holes are machined on the outer ring of the bearing.。Main use: It is suitable for precision instruments, low noise motors, automobiles, motorcyclesand general machinery.It is the most widely used type of bearing in the machinery industryZHEJIANG WAXING ELECTROMECHANICAL CO.LTD.
