1. Self-aligning ball bearing has two rows of balls and a common concave sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.

Compared with plain bearings, deep groove ball bearings of the excellent Compared with plain bearings, deep groove ball bearings of the inferior 1, the general conditions, the efficiency and fluid dynamic bearing lubrication bearing considerable, but higher than the number of hybrid bearings;  1, less able to withstand impact loading; 2, radial clearance is small, angular contact bearings can be used to preload cardiac

1, no backlash, high rigidityPreloading ball screw can be added, as pre-clearance to negative axial pressure can then be more rigid.2, high-precision guaranteeBall screw by a high level of consistent production out of machinery and equipment to produce higher accuracy.3, micro-feed mayAs the ball screw is the use of ball movement, so a very small starting torque, does not appear as a creeping phenomenon of sliding movement can ensure accurate micro-feed.

1: ntn bearing the international standards:China Bearing Industrial Association (CBIA)American Bearing Manufacturers Association (ABMA)American National Standards Institute (ANSI)Japanese Industrial Standards Committee (JISC)Standards Engineering Society
International Organization for Standardization (ISO)Scandinavian Bearing Association (SBA)German National Standards Organization (DIN)
Japanese Standards Association (JSA)Typically, ntn bearing the criteria used are ISO standards.

ntn bearing kit and the outer ring of the processing methodsntn ball bearings machining process: ntn ball bearing raw materials processed by the state of the same vary, cut or ball of light which fell before the process can be divided into the following three, before heat treatment processes, but also divided into the following two kinds,the whole process are: bar or wire stamping (stamping bar after some red zone and annealing needed) - fell cut, coarse grinding,

1: ntn bearing speed operation:1. Analysis of cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage system. There is also suitable for high-speed rotation of synthetic resin molded cage)2. Analysis of Lubrication (used for high-speed spin cycle lubrication, spray lubrication, oil mist lubrication and oil lubrication Lubrication)3. Of bearing internal clearance (taking into account the bearing temperature rise generated internal clearance reduction)

1: ntn bearing quenching oil Optional:1. Ordinary quenching oil (oil temperature at 60 ℃ for quenching)Ordinary quenching oil is mainly applied to better hardenability alloy, such as small size bearing steel, mold steel part quenching. The past, only with different grades of domestic mechanical oil as quenching oil. The early 20th century 80, in order to improve the performance of oil cooling, thermal oxidation stability and rust resistance, mechanical oil added to the reminder of cold,

1: ntn bearing deposit:1.ntn bearing the correct storage method is to ntn bearings placed in horizontal position, bearing ring should be supported throughout the side. If the bearing to the location of the vertical display, due to the relatively small thickness of bearing ring,bearing rings and rolling bodies may lead to bearing the weight of the permanent deformation.2. Stockroom of the relative humidity of not more than 60%, little change in temperature,
