Plain bearings, generally, could be the most affordable sort involving bearing. They're also compact and lightweight, and they've a higher load-carrying capacity.

spherical roller bearings is mainly composed of a spherical inside the circle and the outer within a sphere, can bear larger load. According to the different types and structures, it can bear radial load and axial load or radial, axial and existing joint load. Due to the sphere, the circle with composite materials, the bearings in work can produce self-lubrication. Commonly used for low speed of swing motion, also can be in certain scope for tilting Angle motion, when the axis and axle shell hole concentricity, still can work normally. ChengYing joints for self-lubrication auxiliary machine, hydraulic industry etc.

Spherical plain ina bearing is widely applied in engineering, hydraulic oil cylinder metalforming machine, engineering machinery, automation equipment, automotive shock absorber, hydraulic machinery industry etc. spherical plain bearing profile and classification of spherical plain bearing is spherical sliding bearing, basic is by sliding surface contact with spherical surface of the inner and outer. According to its structure and types of different, can bear radial load and axial load, radial, axial or is the effect and combined load. Because of the spherical roller bearings  spherical sliding large contact area, dip Angle, also because most of the spherical plain bearing special processing methods, such as surface phosphating, galvanization, chrome or sliding surface and lining mat, spraying, etc. So have bigger load capacity and impact resistance ability, and have corrosion resistance and wear, self-aligning and lubrication good or lubricated non-lubricated dirt, dislocation even also can work normally. Therefore, thespherical plain bearingsare widely used in low speed of swing motion, tilt movement and rotation.

Import spherical roller bearings , such as SB type, type, GE, CF series, and the amount and type of other types of the joint fag bearings and fixed-end joint bearings, etc.

SKF GE-45-ES-2RS spherical roller bearings  requiring maintenance have the sliding contact surface combination steel-on-steel. SKF bearings with this sliding contact surface combination require regular relubrication. The high wear resistance of the sliding surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated. 

spherical roller bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface,which enables it to tolerate large load.According to their types and configuration,it can tolerate axle and radial load as well as conbined axle and radial load.Since it has composite material on the outer sphere of the inner ring,thus it can produce self-lubricating during work. Self-lubricating [spherical roller bearings]  applies in water conservancy,specialized mechinery and other industries.Because of the large sphere slidinig contact area and tilt angle of the plain bearing ,as well as most of the spherical roller bearings take special craft treatment,such as surface phosphating, galvanization,chromate treatment,and inlaid mats, spray coating and so on,thus, it has larger load capacity and anti-force capability,as well as anti-corrosion,wear resistant,sel-aligning and self-lubricating features.They can work normally even if it installed mismatch. Therefore,spherical plain bearing are widely used in low-speed swing motion,tilt and rotation movement.
