Product Details
Single row angular contact ball bearings:  This kind of bearing locking in the outer ring, inner and outer rings can not be separated, can be combined radial and axial loads and axial loads in one direction . Axial load capacity determined by the contact angle , the contact angle is larger, the ability to withstand high axial loads . This kind of bearing shaft or housing to limit axial displacement in one direction .
     Single row angular contact ball bearings can withstand axial load in one direction , the radial load, will cause additional axial force. And the only limit shaft or housing in a direction of axial displacement . Angular contact ball bearing contact angle of 40 degrees , so you can bear large axial load. Angular contact ball bearing non- separation type design , inner and outer rings on both sides of the shoulder uneven . In order to improve the bearing load capacity , which would lower side of the shoulder machined , so that the ball bearings can be put more .
Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load , limiting both the axis of the axial displacement . Mainly used to limit the axial displacement of shaft and housing components in two-way double row angular contact ball bearings , the outer ring is limited between the tiltable , allowing the tilt angle depends on the bearing internal clearance , bearing size, internal design and acting on the bearing force and moment , and the maximum allowable tilt angle should ensure that the bearing will not generate excessive additional stress . If the bearing inner and outer angle of inclination between will affect bearing life , also causing precision bearings running down , running noise increases . Double row angular contact ball bearings generally use nylon cage or solid brass cage . Double row angular contact ball bearing installation should pay attention , although bearings can withstand axial load, but if there is one side of the gap when the ball should be careful not to let the main axial load through the notched side of the gutter . Note that the bearing should be used without the ball gap to bear the main load side of the raceway .
The material properties of ZrO2 Bearing : Pure ZrO2 is white, with yellow or gray impurities , generally contain HfO2, easily separated . The world's proven resources of approximately 19 million tons of zirconium oxide, zirconium is usually caused by zirconium ores purification system. At atmospheric pressure pure ZrO2 There are three crystal : monoclinic (Monoclinic) zirconia (m-ZrO2), Quartet (Tetragonal) zirconia (t-ZrO2) and cubic (Cubic) zirconia (c-ZrO2), the three crystal type exist in different temperature ranges , and can be transformed into each other :
Zirconia forming: forming a zirconia ceramic dry pressing , isostatic pressing , slip casting , hot die casting , tape casting , injection molding, extrusion molding plastic , colloidal solidified molding. Which is the most widely used injection molding and dry pressing .
   Sintered zirconia : zirconia ceramic sintering method can be employed generally are: ⑴pressureless sintering , ⑵hot pressing sintering and reactive hot pressing sintering , ⑶hot isostatic pressing (HIP), ⑷microwave sintering , ⑸high pressure sintering, ⑹spark plasma sintering (SPS), ⑺situ compression molding and sintering . Often dominated by pressureless sintering .
Structural ceramics , zirconia ceramics as a high bending strength and high wear resistance , excellent thermal insulation properties, thermal expansion coefficient close to the steel, etc., it is widely used in the field of structural ceramics .
