The roller guide system of the LFR series guide roller bearing has the following characteristics  :

  1. High speed, low resistance and long life . The outer ring surface
    of the LFR series guide rollers of Linqing Zhonghai Jinggong Bearing Manufacturing Co., Ltd. is designed in a Gothic shape, so that when the rollers work, the roller and the guide rail form two angles of 60 degrees. Point contact, low friction resistance, uniform load, avoiding the stress concentration and boundary effect caused by installation and manufacturing errors in the work of the roller, so that the guide rail system has the working characteristics of high speed, low energy consumption and long life.
  2. The installation is simple and convenient. The
    eccentric shaft and the concentric shaft of the guide rail roller bearing make the installation very convenient. Adjust the eccentricity of the eccentric guide rail roller bearing to obtain a suitable preload.
  3. Stable operation, small error, and extremely low operating noise. The
    special processing equipment and testing equipment for the bearing ensure the accuracy of the roller shape. The mature processing technology and strict quality inspection process make all the outer ring of the roller radial runout and working surface The roundness is good, so that the error of the rail system during operation is minimal, the operation is stable, and the operation noise is extremely low.
  • LFRseries guide rail roller bearingsare the most widely used, economical and practical products among linear guide rollers. They can be adapted to cylindrical guide rails with stable operation, small error, extremely low operating noise and high operating speed.
    ●  The contact between the roller and the guide rail is two-point 60- degree contact, which has good contact performance and low running resistance, so as to achieve a relatively long service life.
    ●The  roller adopts the internal structure design of double row angular contact ball bearing and the thickened outer ring, so that the roller has a higher load capacity. The roller bearing is equipped with an eccentric wheel and a concentric shaft and is easy to install.
    ●The  rollers are made of high-quality bearing steel or stainless steel, processed by heat treatment and precision grinding, and filled with long-life, high-quality, multi-purpose grease. The roller dust-proof adopts metal dust cover (KDD) or rubber sealing ring (NPP) .
