Cross roller bearing products selection guide

Cross roller bearing products selection guide is 2020 - 02 - In cross roller bearing, cylindrical roller faith in show 90 & deg; On V groove rolling through the isolation piece is arranged vertically, each other so cross roller bearings can withstand radial load, axial load and torque load in the direction of the load. The size of the inside and outside the circle is miniaturization, thin form is more close to the limit of small size, and high rigidity, so more suitable for industrial robot joints and rotation, the rotation of the machining center machines, mechanical rotary department, precision rotary worktable, medical machinery, measuring instruments, such as IC manufacturing plant equipment. Rotating accuracy, bearing the vertical alignment between roller is equipped with isolation, to prevent the tilt of the roller and roller friction between, reduced the rotary torque. In addition, compared with before using steel retainer, the roller edge stress concentration or lock phenomenon will not happen. At the same time, because of the inner ring or outer ring is two integral structure, bearing clearance can be adjusted, even if the preloading are imposed, can also be high precision rotate smoothly. Cross roller bearing type: 1, RB, Inner circle as a whole, the outer ring fission) The basic model for the cross roller bearings. Outer ring is divided into two pieces, the inner ring to the whole structure, it is more suitable for inner ring rotation accuracy required. Type 2, RE ( Inner ring, outer ring fission overall) For cross roller bearings basic same, appearance is same size and type RB, but for the outer ring the overall structure, inner ring is divided into two pieces, it is more suitable for outer ring rotation accuracy required. 3, RU ( Inside and outside the circle as a whole, with mounting holes) , due to the outer ring and inner ring are mounting holes, do not need fixed flange and brackets when installation. In addition, the outer ring and inner ring are based on the overall structure, the installation will have little impact on performance, thus can obtain stable rotation precision and torque, suitable for the occasion of outer ring and inner ring spinning. 4, RA ( Inner circle as a whole, the outer ring fission, ultra-thin) This model is to decrease the thickness type RB inside and outside the circle to the limit of the compact, the structure and type RB as outer fission structure, more suitable for the need of light weight, compact design, such as mechanical rotating parts. 5, CRBH type ( Inside and outside the circle of integral type, ultra-thin) , this model is the ultra-thin RU, with ultra-thin design and outer ring and inner ring no mounting holes, and the need to flanges brackets fixed. In addition, the outer ring and inner ring are based on the overall structure, the installation has no effect on performance, and therefore can obtain stable rotation precision and torque, suitable for the outer ring and inner ring spinning but size miniaturization requirement. 6, SX type ( Inner circle as a whole, outer ring size, ultra-thin) , in the same journal, this type has smaller than RB types, the section size of the adoption of ultra-thin design, outer ring and inner ring no mounting holes, and the need to flanges brackets fixed, applicable to the inner ring spinning. （ Source: hong yuan bearing)
