Bearing industry commonly used classification ( A)

CNC lathe bearing spindle bearing bearing as basic facilities for the CNC lathe parts, its immediate harm to the numerical control lathe features speed ratio, rotation precision and rigidity, chatter vibration machining, the noise resistance, heat and thermal deformation, etc. , thereby endangering the production and processing precision of parts, process performance, etc. Therefore, the excellent performance of CNC lathe is important to apply the excellence performance of bearings. Especially high speed precision CNC machine tool numerical control lathe bearing. The precision of the rolling bearing is generally divided into P0, P6, P5, P4 and P2 five levels, to fine lathe spindle bearing precision should be on the P5 and with superior leadership, and for the CNC lathe, CNC machining center contour line speed, high precision of the machine spindle bearing support, need to adopt P4 and hyperfine bearing with superior leadership. Numerical control lathe with spindle bearings bearings generally contain concave groove ball bearings, angular contact to touch the ball bearings, cylindrical roller bearings, double torsion Angle to touch the ball bearing, tapered roller bearing and torsion bearing characteristics of six kinds of structure. Printing equipment bearing bearing printing device to a piece of paper printing equipment and printing equipment of the main roller paper roll. Because of the diversity of use requirements, not only part of the printing equipment bearing can accomplish standardization. So printing equipment bearing including many sizes and specifications. Except typicality of two columns, high precision cylindrical roller bearing NN, NNU, N4N, N4U, also contains no 帯 帯 or stop ring ring of bearing module, precise positioning bearing module, irregular graphics bearings, linear and rotary bearing module composition module and circular cone roller bearings. Bearing a 帯 sealing and 帯 sealing two kinds. For cylindrical or conical barrel on both sides of the motor shaft to design. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
