Sepcification:

Angular contact ball bearings can bear radial load and axial load at the same time and also can bear pure axial load. Their ability of axial load is determined by contact angle and is increased with contact angle increasing; speed limit is higher; stiffness is big and can be pre-adjusted. They are applicable to high-speed and high-precision site.

Product application:

- spindle and other high speed precision mechanical spindle

- aircraft engine spindle

- high frequency motor

- printing machinery

- air compressor

- gas turbine

- jet engines

- turbines

-pump

Q:Can angular contact ball bearings be adjustable?: You say, of course notHave you seen when you spend RMB Mingbi useful

Q:What is angular contact ball bearing contact angle?: Angular contact ball bearings can simultaneously bear axial force and radial force in one direction. The rolling force of upper and lower points of attachment at a certain angle and radial direction. Such bearings are angular contact bearings.

Q:Two angular contact ball bearings, the use of clearance problems: No adjustment required,DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.

Q:What are the differences between angular contact bearings AC and A and C?: Angular contact bearings common suffix has AC, C and B, AC said nominal contact angle a is 25 degrees, C is 15 degrees, B is 40 degrees.

Q:How many angles are there in angular contact ball bearings? How many degrees are they?: A stands for 30 degrees, A5 stands for 25 degrees, B stands for 40 degrees, and C stands for 15 degreesThe new Seiko NSK serves you!

Q:Angular contact ball bearings, how to judge the size of the mouth?: Yes, look at the outer ring of the bearing. The thinner end is the big one.

Q:What is the difference between deep groove ball bearings and angular contact ball bearings?: Deep groove ball bearings and angular contact ball bearings are not the same

Q:How can angular contact be distinguished from the front and back? What are the characteristics of each?: Hello, there is a number on the front, no number on the back

Q:What does angular contact ball bearing 70216AC mean?: 7--- angular contact ball bearing0--- normal width series2--- diameter series code, which means light series16--- internal diameter code indicating the inner diameter of 16*5=80mmAC--- internal structure code indicating the nominal contact angle of angular contact bearing is 25 degrees

Q:Is there a way to calculate the axial force of angular contact ball bearings?: The rated axial dynamic load of the bearing is: 4300N. Axial force can be calculated by formula. Please consult the professional manual!
