introduction：Air bearing（Also known as air bearing）It means using gas（Its usually air.，But it could be other gases）Plain bearings as lubricants。Air is less viscous than oil，High temperature resistance，pollution-free，It can therefore be used in high-speed machines、In instruments and radioactive installations，But its load capacity is lower than oil。 Air bearings are divided into three categories：Aerostatic bearing、Air dynamic pressure bearings and extrusion film bearings。In general industry，Aerostatic bearings are widely used。 Working principle of air bearing： Conventional motor spindles are supported by bearings，The higher the speed，Bearing alignment accuracy，The higher the lubrication and other requirements，The shorter the service life。The air motorized spindle manages to suspend the spindle in the air，And can rotate stably and with high precision，Principal axis、The processing precision of air bearing can achieve full speed12Ten thousand revolutions/Points or more。 This suspension is achieved by pressurized air in

introduction：What is self-lubricating bearing？ Self-lubricating bearings are divided into composite self-lubricating bearings，Solid inlaid self-lubricating bearing shaft，Bimetallic material。Self-lubricating bearing，Special material self-lubricating bearings，According to different uses and working conditions，Use different self-lubricating bearings。One of the major classes of solid inlaid self-lubricating bearings(For shortJDB)It is a novel lubricated bearing with the characteristics of metal bearing and oil-free lubricated bearing，The load is borne by a metal matrix，Specially formulated solid lubricating materials play a lubricating role。 It has a high carrying capacity，Impact resistance，High temperature resistance，Self-lubricating ability is strong，Especially suitable for heavy loads，Low speed，Reciprocating or swinging such as difficult to lubricate and form oil film occasions，Also not afraid of water and other acid erosion and erosion。The products have been widely used in metallurgical continuous casting ma

introduction：Rolling bearings if only according to the bearing to bear the external load is different to classify，Rolling bearings can be broadly divided into radial bearings（Mainly bear radial load）、Thrust bearing（It can only withstand axial loads）、Radial thrust bearing（It can withstand both radial and axial loads）。 Radial thrust ball bearing，The bearing of this structure，It can withstand radial loads and axial loads in one direction。Find the inner circle、Have an outer ring 15 The degree of、 25 The degree of、 30 Kwoku 40 Degree contact Angle。The greater the contact Angle，The greater the axial load bearing capacity。The smaller the contact Angle，The more favorable it is for high-speed rotation。 usual，Set the two bearings against each other，Adjust internal clearance before use。 Radial thrust ball bearing，It belongs to a class of bearings that can withstand both radial and axial forces，Its actually an angular contact bearing，The two are the same concept，Formerly called centripetal thrust，Now call it angular contact。O

introduction：The rolling element is the centripetal rolling bearing of a cylindrical roller。The internal structure of cylindrical roller bearings is arranged in parallel with rollers，A spacer or spacer block is arranged between the rollers，It can prevent the tilt of rollers or friction between rollers，The increase of rotational torque is effectively prevented。 Bearing characteristic： The cylindrical roller is in linear contact with the raceway，Large radial load capacity。It is suitable for bearing heavy loads and impact loads，Also suitable for high-speed rotation。The raceway and rolling body of cylindrical roller bearing are in geometric shape。After an improved design，It has a high carrying capacity，New structural design of flange and roller end face，Not only improves the axial bearing capacity of the bearing，At the same time, the lubrication condition of the contact area between the roller end face and the rib is improved，The performance of the bearing is improved。 Bearing class： Cylindrical roller bearings ar
