Japan NTN Bearing 5204 Angular Contact Ball Bearing 5204ZZ
Description
Anglular contact ball bearing steel balls and inside and outside the points of contact with the circle attachment radial into a point of view. Contact Angle generally divided into 15 °, 30 °, 40 °, respectively for the letter C, A, B says, NSK special production contact Angle for 25 ° of these bearings, with the A5 said. Angle contact ball bearing main bear big one-way axial load, the greater the contact Angle, the greater the ability to bear a heavy load. Maintains a material with a steel, brass or engineering plastic, forming a way to have a press or turning, depending on the bearings form or conditions of use different and choose. There are other combined angular contact ball bearing, double row angular contact ball bearing and four-point contact ball bearing.
Angular contact ball bearings are widely used in mechanical industry,like in various machinery such as metallurgic machinery,mining machinery,paper making machinery,exile machinery,etc.
