Structural features and types of IKO spherical plain bearings

The IKO spherical plain bearing adopts a structure in which the inner and outer rings are in spherical contact, and is a self-aligning spherical plain bearing that can withstand large radial loads and bidirectional axial loads at the same time. There are various types of spherical plain bearings, which can be roughly divided into oil-filled and non-oiled types according to the type of sliding surface. The inner and outer rings of the oil-filled spherical plain bearing are made of high-carbon chromium bearing steel, the sliding surface is treated with phosphate film and covered with a dry film of molybdenum disulfide (MoS2), which operates with low torque and has excellent wear resistance and large load capacity. bearing. It is especially suitable for parts with alternating load changes and impact loads, and is mainly used in industrial machinery, construction machinery, etc. IKO oil-free spherical plain bearing is equipped with a special PTFE-lined outer ring reinforced with copper alloy mesh on the sliding surface and an inner ring plated with hard chrome on the sliding surface, which has less creep under compressive load and is excellent in wear resistance. Maintenance-free spherical plain bearings. It is especially suitable for bearing loads in a certain direction, for food machinery and other fields that are not suitable for oil, and for parts of construction machinery that cannot be refueled. Bearing model classification Inch SB SBA GEE, ES GEG, GS SBB Metric series GEES-2RS GEGS-2RS SBB -2RS GEEC ─GEEC-2RS ─ Non-lubricated spherical plain bearings without sealing gaskets with sealing gaskets Oiled spherical plain bearings without sealing The gasket is attached with a sealing gasket. The outer ring of the oil-filled spherical plain bearing SB is a split type, and the outer peripheral groove of the outer ring is equipped with a ring to fix the inner and outer rings. Oil type spherical plain bearing SBA The outer ring of this bearing is a single split type, the inner and outer rings are not separated from each other, 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 dimension series of this bearing conforms to ISO standards and is global. The outer ring is a single split type, which is divided into GEE and GEES according to the size of the bearing. GEES comes with a gasket. The double-lip-shaped urethane gasket has the function of preventing grease leakage and dustproof. It is indicated by -2RS at the end of the nominal model number. Oil-filled spherical plain bearings GEG and GEGS bearings have larger load capacity and allowable inclination angle than GEE and GEES, and their dimension series conform to ISO standards and are global. The outer ring is a single split type, and is divided into GEG and GEGS according to the size of the bearing. GEGS comes with a gasket, and the double-lip-shaped urethane gasket has the function of preventing grease leakage and dust. IKO oil type spherical plain bearing SBB This bearing is an inch series, and the outer ring is a single split type. The bearing is equipped with a gasket, and the double-lip-shaped urethane gasket has the function of preventing grease leakage and dust. Oil-free spherical plain bearings GEEC type bearings have the same main dimensions as oil-filled spherical plain bearings GEES, and are global bearings. The sliding surface adopts a special PTFE lining reinforced with copper alloy mesh, which has less creep against compressive load and is a maintenance-free spherical plain bearing with excellent wear resistance. This bearing comes with a gasket, and the synthetic resin gasket has a dust-proof effect, which is indicated by -2RS at the end of the nominal model number. In addition, our company also produces high rust-proof bearings suitable for working in corrosive environments or environments with splashing water.
