When it comes to handling heavy radial loads at high speeds, bearings, especially cylindrical bearings are the most favored ones. They are known for their cylindrical rolling elements that distribute loads evenly across a broad surface. The applicability and suitability of cylindrical bearings are high due to the flexibility they offer in the designs, internal clearance class, dimensions and series. The single-row cylindrical bearings are nevertheless the most desirable components in applications for they are available in standardized sizes. Cylindrical Bearings The improved designs in cylindrical roller bearings offer enough choices when it comes to using them for precision machine tools. The bearing, with a cage is crafted to support rapid accelerations and heavy radial loads at high speeds. When double-row cylindrical bearings offer high radial rigidity, there are full complement bearing designs in these to handle high radial loads at moderate speeds.
Nevertheless, the intrinsic features of the bearing decide the its performance and they are given below: Integral roller flanges: The rolling elements are guided by the integral flanges on the inner and outer raceways. Inclined by a defined angle, these flanges are open and help form a lubricant film during the operation on the contact surface area. This helps reduce frictional heat, as well as thrust. Excellent operational reliability: The hydrodynamic lubricant film formation on the contact surface area helps optimize the rolling movement of the rolling elements in a cylindrical bearing. The formation of the lubricant is maximized because of the raceway contact area and surface finish; thus, offering excellent operational reliability. Even distribution of loads: The logarithmic profile of the rollers enables equal disbursal of loads in the raceway contact area. Consequently, the roller ends do not experience any stress peaks; instead, it offers the bearing a long service life. Furthermore, there are minimal chances of misalignment and shaft deflection because of the roller profile. Interchangeable components: The separable components of the cylindrical roller bearings come in standard sizes, designs and dimensions to facilitate easy interchangeability. A raceway can be easily mounted or dismounted if it belongs to a similar ‘internal clearance class’. When it comes to misalignment, cylindrical bearings, in contrast to spherical plain bearings, can handle misalignment to certain limits by reducing it. In a similar way, they also allow axial displacement to some extent, unlike that handled by a spherical ball bearing. Get to Know Some Types of Cylindrical Bearings for Multiple Applications There are single-row and double-row cylindrical bearings suitable for various applications such as furnaces,rolling mills, railway axle boxes, and so on.The other variations in designs include machined brass or pressed steel cages and also molded polyamide cages based on the application. Thus, there are enough choices when it comes to using cylindrical bearings for any applications.
