Special Features

  • 1.Core definition: Cylindrical roller bearings are an important type of rolling bearings. They are based on parallel raceways and cylindrical rolling elements on the inner and outer rings. They mainly bear radial loads and can also withstand certain axial loads. They have high radial load capacity and good high-speed performance, and are suitable for mechanical scenarios with dual requirements for load and speed.
  • 2.Main Structure: The basic structure consists of an outer ring, inner ring, cylindrical rollers, and a cage. Some models also include seals or dust covers. The inner and outer ring raceways are cylindrical, and the rollers are cylindrical and parallel to the raceways. The cage evenly separates the rollers, reducing friction and collision. Seals prevent lubricant loss and impurities from entering, extending service life.
  • 3.Common types: There are two types according to structural differences. One is single-row cylindrical roller bearings. The NU type has no inner ring ribs, while the NJ type has a single inner ring rib. The other is double-row cylindrical roller bearings, which have a stronger radial load capacity and are suitable for heavy machinery. In addition, there are models with cages or full complement rollers.
  • 4.Typical Applications: Widely used in high-load, medium-speed equipment, such as motor spindles, machine tool spindles (requiring high precision and high load capacity), automotive gearboxes, mining machinery (for heavy load scenarios), and wind turbines (tolerance to long-term radial loads).
