Some Categories of NSK Ball Bearings
NSK Company is known to many people in this world. Its products have contributed greatly to the growth of many industries and to the advancement of mechanical technology. Customers can find extensive information on its high-quality products, such as bearings, automotive products, and precision machine components.
Well, among all the different products, NSK bearings are quite famous. They can be applied in various industries. As for the company, ball bearing products are a large part and they play a very important role in the development of the company. And ball bearings can be further divided into many other kinds, i.e. deep groove ball bearings, self-aligning ball bearings, angular contact ball bearings, and thrust ball bearings.
NSK manufacture a full range of deep groove ball bearings. They are the most common type and are used in a wide variety of applications. One kind is called single-row deep groove ball bearings. They are the most common type and their usage is very widespread. These bearings often have steel shields or rubber seals installed on one or both sides. They can be commonly used in steel industry; motorcycles and railways.
Self-aligning ball bearings are recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Of course, they can also be used in many related industries. For example, they can be used in the papermaking machinery. To meet the requirements of customers, NSK has developed a range of products and the company's bearings are used in all sections of modern papermaking machines. In particular, NSK is supporting papermaking with two kinds of bearings: one is bearings with tough and long life which is designed specifically for dryers. These were developed by taking full advantage of the company's material heat treatment technologies. The other is NSKHPS Spherical Roller Bearings developed by integrating NSK's materials, design and manufacturing technologies.
The NSK range of angular contact ball bearings has been designed to meet the increasingly demanding requirements of original equipment manufacturers. For instance, double-row angular contact ball bearing is basically a back-to-back mounting of two single-row angular contact ball bearings, but their inner and outer rings are each integrated into one. They can be applied in the industries like mining & construction, electric motors, etc.
Addition to the above kinds of products, there are still many other categories. All in all, NSK will continue to develop highly reliable bearings that will continue to contribute to the development of the industry.

What radius (in mm) must a steel (iron) ball bearing have if it is to have a mass of 1.25g?
What radius (in mm) must a steel (iron) ball bearing have if it is to have a mass of 1.25g?
V = 4/3(pi)r^3
Density of Iron = 7.7874
Mass = 1.25
Volume = .1605
Work shown would be appreciated, Thanks in advance.
Mass = 1.25g = 0.00125kg
Density = 7787.4 kg/m3
V= mass / density = 1.605e-7m3
V = 4/3(pi)r^3 = 1.605e-7 m3
r^3 = ( 1.605e-7 * (3/4) ) / pi
= 3.83 e-8 m3
r = Cubed root of 3.83 e-8
= 3.37e-3 m *1000 = 3.37mm (i find it easier working in metres)
