Descriptions of Japanese industry spherical plain bearing GEG60ES
Spherical plain bearings can carry a high capacity of radial and axial loads in a small envelope due to a large contact area.  They are suitable for static oscillatory applications where moderate misalignment may be common, such as in mining and construction applications.

Spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be possible at relatively slow sliding speeds.

Spherical plain bearings requiring maintenance have the sliding contact surface combination steel-on-steel. 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. Bearings which have cylindrical extensions at both sides of the inner ring are intended for applications where normally spacer sleeves are arranged at either side of the bearing, or are specially designed for the bearing arrangements of hydraulic cylinders.

Spherical rollers are put between the spherical raceway on the outer ring and the two grooves on the inner ring for there bearings. Since the center of the arc raceway on the outer ring is the same as the center of the whole bearing arrangement, there bearings are self-aligned and automatically adjust the bending of the shaft and housing and the eccentricity. The bearings can carry radial load and axial load in double directions. The especial radial load carrying capability makes there bearings suitable for heavy load and shock load carrying.

Spherical Plain Bearings are self-aligning spherical plain bushings that have inner and outer rings with spherical sliding surfaces, and can take a large radial load and a bi-directional axial load at the same time.

Steel-on-steel Spherical Plain Bearings have inner and outer rings of high carbon chromium bearing steel, of which sliding surfaces are phosphate-treated and then dry-coated with molybdenum disulfide (MOS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity.

 Classification and features of Japanese industry spherical plain bearing GEG60ES

Joint bearing can bear larger load. According to their different types and structure, 

can bear radial load, axial load and radial, axial and the existence of joint load. Because 

of the inner ring of the outer spherical surface with composite material, so the bearing in 

the workplace can generate self lubrication. Commonly used for low speed of swinging 

movement, and the low speed rotation, also can be in a certain angle range for tilting 

movement, when the supporting shaft and the shaft hole of the shell are not concentric 

degree bigger when, can still work normally. Joint self-lubricating bearings used in water

conservancy, specialized machinery etc..
