introduction：The characteristics of cylindrical roller bearings are，High load carrying capacity、High stiffness、Allowable radial displacement，Except for bearings with inner and outer ring flanges。 Low friction：Open flange design，Work with roller end design and surface finish to promote lubricant film formation，Lower friction and higher axial base load rating。 Long service life：The roller logarithmic curve contour reduces the roller/Edge stress at raceway contact，And sensitivity to misalignment and axial flexure。 Improve operational reliability：The surface finish of the contact surface between the roller and the raceway is conducive to fluid movement Formation of a pressure oil film。

introduction：Knuckle bearings are widely used in engineering hydraulic cylinders,Forging machine,Construction machinery,Automation equipment，Shock absorbers for cars，Hydraulic machinery and other industries. Introduction and classification of knuckle bearings Knuckle bearings are spherical plain bearings，The basic type consists of an inner surface with a spherical sliding spherical contact、Outer ring composition。Depending on its structure and type，Can withstand radial load、Axial load，Or radial、Joint axial loads acting simultaneously。Because the spherical sliding contact area of the joint bearing is large，The Angle of inclination is large，At the same time, it is also because most of the joint bearings have adopted special process treatment methods，Such as surface phosphating、galvanize、Chrome plated or outer sliding surface lining、Insert packing、spraying。Therefore, it has a large load capacity and impact resistance，And has corrosion resistance、wear-resistant、self-centering、The characteristics of good lubrication or self-lub
