关节轴承是一种球面滑动轴承,宜于做倾斜或旋转的摆动,具有自调心的作用。自润滑关节轴承是在轴承外圈内球面粘贴一层自润滑衬垫材料,用衬垫滑动表面对内圈外球面的滑动摩擦代替钢表面的滑动摩擦。自润滑关节轴承具有结构紧凑、重量轻、耐冲击、耐腐蚀、承载大、使用寿 Spherical plain bearings are spherical bearings, suitable for tilt or rotation of the swing, with self-aligning effect. Self-lubricating spherical plain bearings are made by attaching a layer of self-lubricating cushioning material to the spherical surface of the bearing outer ring, replacing the sliding friction of the steel surface with the sliding friction of the sliding surface of the lining on the outer spherical surface of the inner ring. Self-lubricating bearings with a compact, light weight, impact resistance, corrosion resistance, load capacity, service life
