Spherical plain bearings

Product Description

Joint Bearings is a special structure of sliding bearing. Its structure is simpler than the rolling bearing, which is mainly an inner and outer sphere within a sphere composed of the outer ring, can bear a greater load, according to its different types and structures that can bear radial load, axial to load or radial, axial joint loads exist. Spherical Plain Bearings are generally used for slower swing movement (that is, angular motion), as the sliding surface of the spherical shape, is also available at a certain angle to tilt within the movement (ie, self-aligning movement), in the supporting shaft axis and shell holes of different heart degree is large, still work properly.
Spherical plain bearingsor bushings, are metal-on- spherical plain bearingsconsisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications. Size range: Available from *5 mm - **0 mm (0.**0 in. to *3.**2 in.) bore Design Attributes Rings manufactured from hardened steel help deliver consistent, reliable performance. Phosphate-treated rings coated with molybdenum disulfide (MoS2) minimize friction of contacting surfaces. Simplified housing and shaft designs reduce installation time.Joint bearingapplications A-frames, dump cylinders, front and rear struts, and steering cylinders for mining trucks Equalizer track bars, lift and tilt cylinders,spherical plain bearings push blades, trunnion balls and ripper blades for bulldozers Articulated joint upper and lower steering cylinders and boom and bucket cylinders for wheel loaders Stick and bucket cylinders for hydraulic excavators Additional applications for space shuttles,joint bearingheavy movable structures and miscellaneous vehicles .
