Product Details


Deep groove ball bearings are bearing the most common type . Basic deep groove ball bearing is composed of an outer ring, an inner ring, a set of balls and a group holding structure into . Deep groove ball bearing type has two kinds of single and double row deep groove ball structure also split seal and open two structures, open means bearing structure without seal , sealed deep groove ball into dust seal and oil seal. Dust Gland Material steel stamping , just play simple to prevent dust from entering the bearing raceways . Oil- proof seal for the contact , which can effectively prevent the grease within the bearing spillover . Single row deep groove ball bearing type code 6 , double row deep groove ball bearing code is 4. Its structure is simple , easy to use , is the production of the most common , the most widely used class bearings. Deep groove ball bearings mainly take radial load , but also to support radial load and axial load. When the only radial load , the contact angle is zero. When the deep groove ball bearings with a larger radial clearance , the performance with angular contact bearings can bear large axial load , deep groove ball bearing friction coefficient is small , limit speed is also high.

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 .

    Zirconia bearing performance : Zirconia bearings with high temperature, cold , wear resistance, corrosion resistance , anti-magnetic insulation , self-lubricating , high- speed and other features . Can be used in extremely harsh environments and special conditions , can be widely used in aviation , aerospace, marine , petroleum, chemical, automotive, electronics, metallurgy , electric power, textile, pumps , medical equipment , scientific research and national defense and military fields , is the application of new materials, high-tech products . Ceramic bearing rings and rolling all- ceramic materials, zirconium oxide (ZrO2), silicon nitride (Si3N4), silicon carbide (Sic), alumina (AL2O3) of four. Holder PTFE , nylon 66 , polyether imide , zirconium oxide , silicon nitride , stainless steel or special aviation aluminum, thereby expanding the surface of the ceramic bearing applications .

    Zirconia bearing installation : When installing the bearing , the end face of the ferrule should exert equal pressure on the circumference , as the ferrule into strictly prohibited directly with a hammer and other heavy percussion bearing face , so as not to damage the bearings ! Moreover , if ferrule party ( eg outer ) pressure while rolling the ferrule through the other ( eg inner ) push , which often cause indentations in the raceway or abrasions, and must not use . In particular the non-separable type of bearing is also installed in the shaft and the bearing housing shown in Figure 1 : the inner and outer rings with the horn push balanced .

Two ceramic bearings with

    (I) the amount of interference

    The inner and outer roller bearing fixed to the shaft or the bearing housing , when it receives a load , the ferrule and the shaft or the bearing housing does not occur with the surface radial, axial and rotational direction of the relative movement . This relative movement will occur with surface wear, friction cracks, corrosion or friction , as well as causing the bearing , shaft and bearing housing damage, then wear flour mixed with the bearing, be a cause of dysfunctional , abnormal heat or vibration causes.

    Fixed bearing on the way to the ring and shaft or bearing housing mating surfaces aside the amount of interference , for static tie for the best. The thin ring with the load can be distributed equally on the circumference , without affecting load bearing capacity .

    However, the use of static with , in addition to bearing installation and removal convenient , the free side bearings with separate bearings , axial movement can not , therefore, can not be used for all occasions .

    (Ii) with the choice

    With generally chosen according to the following principles.

    According to direction of the load acting on the bearing , nature and one inner ring which is rotated, the load on the ring can be divided into rotational load , static load or a non-directional load. Rotate the load and do not bear the load of the ring should be taken as directed interference fit ( interference fit ) , to withstand static load rings, desirable transition fit or moving with ( clearance fit ) .

    Bearing load is large , or to withstand vibration , shock load, to increase the interference . The hollow shaft , thin-walled bearing housing or light alloy , plastic bearing housing , they should increase the amount of interference .

    High rotation precision is required to maintain the required high-precision bearings , shaft and the bearing box and improve the dimensional accuracy , to avoid excessive interference . If the interference is too large , may be the shaft or the bearing box geometry Accuracy of geometry of the bearing rings , to the detriment of the bearing rotation accuracy.

    If not separable bearings ( such as deep groove ball bearings ) with static inner and outer rings are used , then the bearing installation and removal is extremely inconvenient , it is best to use inside and outside the ring moving with a party .

    (Iii) Recommended fits

    About installing the bearing shaft and the shaft bearing housing , the aperture size tolerance , in the metric series , ISO286 ( dimension tolerances and fits ) have corresponding standards . Therefore, tolerances have been selected with the shaft, the aperture size tolerances may be. Figure 2 shows the pore size commonly used in the journal and the bearing inner and outer diameter tolerances with the relationship .

Third, ceramic bearings and classification code

    Ceramic bearings listed in this description represent on the suffix code to "Ce" as the symbol. The structure and composition is divided into: Full ceramic bearings and ceramic bearings combination . Wherein : ceramic bearing means , the outer ring and rolling elements are all with zirconium oxide (ZrO2), silicon nitride (Si3N4), silicon carbide (SiC), alumina (Al2O3) and other ceramic materials and manufactured according to user needs ;
