NSK Bearings through the "MOTION & CONTROL" (operation and control) technology, in order to build a comfortable and safe community dedication. While safeguarding the global environment, we should strengthen our solidarity and cooperation among nations, people and people through undertakings in the world.
Japan's Seiko Co., Ltd. (NSKLTD) was established in 1916, Japan is the country's first design and production of bearings manufacturers. For decades, NSK has developed countless new bearings to meet the needs of users all over the world, and has made great contributions to industrial development and technological progress. At the same time NSK relies on its technical advantages in precision machining to continuously develop high, refined and advanced products such as auto parts and precision mechanical components and actively carry out diversified operations in the field of electronic applications.
Gradually establish and perfect the trinity business system with production as the core, technology as guidance and marketing information as an aid. NSK will speed up the localization of this system so as to provide more direct and complete services for the vast number of users in China. China's industrial modernization make its due contribution.
NSK thrust ball bearings with high-speed operation can withstand the thrust load design, with the ball rolling raceway washer-like ring composition. As the ferrule is cushion-shaped, therefore, the thrust ball bearings are divided into flat-type cushion type and self-aligning spherical cushion type two types. In addition, this kind of bearing can bear the axial load , but can not bear the radial load.
1. With one-way, two-way two types
2, Thrust ball bearings can only bear axial load, one-way thrust bearings can only bear one direction of axial load, two-way thrust bearings can withstand alternating axial load in both directions.
Thrust ball bearings can not limit the radial movement of the shaft or the box, its limit speed is low, the one-way thrust bearing can limit the axial movement of the shaft or the box side, two-way bearing can limit the shaft or box in two Direction of the axial movement.
4, when using this bearing, if the axis of the shaft hole and the box is not the same heart, it will cause premature bearing damage, in order to eliminate this undesirable phenomenon, can be set aside between the outer diameter of the living ring and the box hole 0.5 ~ L mm radial clearance. At the same time, it is also required that the axis of the shaft and the support surface of the box should be vertical. In order to eliminate the tilt of the bearing center caused by the box support surface not perpendicular to the shaft centerline, an elastic lining material may be padded on the support surface of the living ring, Varnish, leather and oil-resistant rubber pads.
5, Thrust ball bearings in operation, due to the role of inertial force, but also between the ball and the raceway to produce sliding, leaving the temperature increases, the work surface easily damaged. Therefore, in order to prevent the ball sliding between the raceways, thrust ball bearings in the work must be minimal axial force.
6. In order to allow installation error, either one-way or two-way, can choose spherical self-aligning spherical seat type or spherical seat type.
