Cylindrical roller bearing structure and purpose

  Cylindrical roller bearing internal structure using cross roller arranged perpendicular to each other (which is also cross roller bearings origin of the name), equipped with the interval between the roller cage or isolation block, you can prevent mutual ground between the tilt roller or rollers police, effectively preventing the increase in rotational torque. Cylindrical roller and raceway for the line contact bearings. Load bearings for printing machine , the main radial load. The rolling element and ring wall friction is small, suitable for high-speed rotation. Inner or outer wall of the cylindrical roller bearings, the inner and outer rings relative to the axial movement can therefore be used as free-end bearings. On either side of the inner and outer double wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction. General Crossed Tapered Roller Bearing  of steel stamping cage, or copper alloy machined solid cage. But there are also some use of polyamide forming cage. Cylindrical roller bearing raceways and rolling lanes geometry. After the improved design, with a high load carrying capacity, the new design ribs and roller end, not only improves the axial bearing capacity, while improving the roller end contact area with the wall lubrication conditions, improved performance of the bearing. Cylindrical roller bearings are separable bearings, installation and removal is very convenient. Cylindrical roller bearings can withstand greater radial load and applies to the use of lead in high speed applications. Double row cylindrical roller bearings: double row cylindrical roller bearings are swimming bearings, the separability makes installation and removal easy. Two rings can be a tight fit. Double row cylindrical roller bearings almost not allowed to have the tilt angle.
