In the field of machine tool manufacturing, high-precision bearings can be called the "heart" of machine tools, and their performance directly affects the machining accuracy, stability and service life of machine tools. For a long time, domestic machine tool manufacturers have been highly dependent on imports for high-end bearings, which is not only high in cost but also unstable in the supply cycle, which seriously restricts the development of enterprises and the improvement of market competitiveness. In order to break through this dilemma, Hebei Bearing Industry Technology Research Institute (hereinafter referred to as the Provincial Bearing Research Institute) has successfully launched a series of high-precision supporting bearing sets to meet the strict needs of the machine tool industry, with stable accuracy above P4 level, and excellent stability and durability during high-speed operation. The quality of these products meets or even exceeds the imported similar standards, realizes the localization of key bearings, and breaks the international monopoly.
The cost-effective advantage is highlighted, adding impetus to enterprises to reduce costs and increase efficiency
In terms of cost control, the high-precision supporting bearing group of the Provincial Bearing Research Institute has shown significant advantages, and the price is only about half of that of imported bearings. Taking the common specification bearings of machine tool spindles as an example, the unit price of imported brands can reach thousands of yuan, while the same specification products of our institute only cost more than 1,000 yuan. This price advantage will greatly reduce the production cost of machine tool manufacturers, effectively improve the profit margin of enterprises, and help domestic machine tools grasp the price initiative in market competition.
Customized solutions to accurately match industry needs
The high-precision supporting bearing group of the Provincial Bearing Research Institute not only has advantages in quality and price, but also provides intimate customized services to provide high-quality and low-cost solutions for domestic machine tool manufacturers.
High stiffness cylindrical roller bearings: suitable for high-load precision spindle scenarios
Single row cylindrical roller bearing N10 series and double row cylindrical roller bearing NN30 series can withstand high radial loads, suitable for lathe spindles with high requirements for rigidity and precision, because the outer ring has no flange, the raceway has no axial constraint on the roller, can compensate for the change of rotational movement length direction, so it is especially suitable as a floating bearing as a free end. By optimizing the internal dimensions of bearings, roller logarithmic busbars, and cage shapes, and using high-standard materials, stable operation in the field of low heat generation and high speed is achieved.
High-efficiency thrust angular contact ball bearing: Construct a stable axial force system
Thrust angular contact ball bearings, BAR10 series, BTR10 series, and 2344 series bear axial loads in the machine tool spindle, and have high rigidity and high speed performance. In the spindle arrangement, thrust angular contact ball bearings are used in combination with tapered bore cylindrical roller bearings that bear radial loads.
As shown in the figure:
Hebei Bearing Industry Technology Research Institute will continue to take technological innovation as the core, provide more accurate and reliable bearing solutions for domestic machine tool manufacturers, and help the machine tool industry move towards a new stage of high-quality development!
