Structural features and models of joint bearings

The joint bearing adopts a structure in which the inner and outer rings are in spherical contact. It is a self-aligning joint bearing that can withstand large radial loads and bidirectional axial loads at the same time. There are many types of joint bearings, according to the type of sliding surface can be roughly divided into oil type and non-oil type. The inner and outer rings of the oil-filled spherical plain bearings are made of high-carbon chromium bearing steel. The sliding surface is treated with a phosphate film and covered with a molybdenum disulfide (MoS2) dry film. It operates with low torque and has excellent wear resistance and large load capacity. Bearing. It is especially suitable for the parts where the load changes alternately and the impact load acts. It is widely used in industrial machinery, construction machinery, etc. The non-lubricated joint bearing is equipped with a special PTFE lined outer ring reinforced with a copper alloy mesh on the sliding surface and an inner ring plated with hard chromium on the sliding surface, which has less creep to the compressive load and is excellent in wear resistance. Maintain joint bearings. It is especially suitable for bearing loads in a certain direction, and is used in areas where oil is not suitable for food machinery and other parts of construction machinery that cannot be refueled. Bearing type classification Inch SB SBA GEE, ES GEG, GS SBB Metric series GEES-2RS GEGS-2RS SBB -2RS GEEC ─GEEC-2RS ─Non-oil-repellent joint bearing without sealing gasket with gasket The gasket comes with a sealing gasket. The outer ring of the oil-filled joint bearing SB is a bisecting type, and the outer circumferential groove of the outer ring is equipped with a ring fixed inner and outer ring. Oil-filled spherical plain bearing SBA This type of bearing has a single-split outer ring, and the inner and outer rings are not separated separately. The operation before installation is easy and it is also easy to install in the bearing seat. The main dimensions are the same as SB and can be used interchangeably, but the radial internal clearance is made smaller. Oil-filled spherical plain bearings GEE, GEES, the size series of this type of bearing comply with ISO standards and are global. The outer ring is a single split type, divided into GEE and GEES according to the size of the bearing. GEES comes with a gasket. The double-lip-shaped polyurethane gasket has the function of preventing grease leakage and dust prevention. It is indicated by marking -2RS at the end of the nominal model number. Compared with GEE and GEES, GEG and GEGS bearings have larger load capacity and allowable inclination angle. The size series conform to ISO standards and are global. The outer ring is a single split type, divided into GEG and GEGS according to the size of the bearing. GEGS comes with a gasket. The double-lip-shaped polyurethane gasket has the effect of preventing grease leakage and dustproofing. Oil-filled spherical plain bearings SBB This bearing is an inch series with a single-split outer ring. This type of bearing comes with a sealing gasket. The double-lip-shaped polyurethane sealing gasket has the effect of preventing grease leakage and dust prevention. Non-oil-filled spherical plain bearings. The main dimensions of GEEC bearings are the same as those of GEES-oil-filled spherical plain bearings. They are global bearings. The sliding surface adopts a special PTFE lining reinforced with a copper alloy mesh, which has less creep to compressive loads and is a maintenance-free joint bearing with excellent wear resistance. This type of bearing comes with a sealing gasket. The synthetic resin sealing gasket has a dust-proof effect. It is indicated by marking -2RS at the end of the nominal model number. In addition, our company also manufactures highly anti-rust bearings suitable for working in corrosive environments or water splashing environments.
