cylindrical roller bearing can be prevented from tilting roller or rollers each other mill inspections

  Cylindrical roller bearing roller internal structure was aligned perpendicularly intersecting each other (which is also cross roller bearings origin of the name), equipped with the interval between the roller cage or isolation block, cylindrical roller bearing can be prevented from tilting roller or rollers each other mill inspections, effectively preventing the increase of rotational torque. Inner or outer cylindrical roller bearing  of the cylindrical roller bearings, the inner and outer rings relative to the axial movement can, so you can use as a free-end bearings. On either side of the inner and outer double-wall, rings on the other side there is a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction. General use steel stamping cage, or copper alloy roller bearing solid cage. But there are also some use of polyamide forming cage. Cylindrical roller and raceway line contact bearings. Load capacity, the main radial load. Rolling ring wall friction is small, suitable for high-speed rotation. Roller and raceway line contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.

Backing bearings for multi-row cylindrical roller bearings

  Backing bearings known as wheel bearings, is a comprehensive load can withstand large bearings can bear large axial, radial load and overturning moment simultaneously. Slewing ring bearings generally with mounting holes, internal gear or external gear, lubrication holes and sealing devices, which can host design compact guide is simple, easy to maintain. Slewing ring bearings with or without gear, external gear type and the tooth-like four-point contact ball bearings, double row angular contact ball bearing Cross cylindrical roller bearings, tapered roller bearings and backing bearing  three-row cylindrical roller bearings four composite series, four point contact ball bearings with high static load capacity, cross-cylindrical roller has a high dynamic load capacity, cross-tapered roller bearings preloaded bearings can have greater support rigidity and rotary precision, three-row cylindrical roller bearings due to increase the carrying capacity of lead Backing Bearings height, were subjected to various forces from different races, so the force under the same circumstances, the bearing diameter can be greatly reduced, and thus there is more compact so that the host is characterized by a high-load capacity of slewing ring bearings. Slewing ring bearings are widely used for lifting machinery, mining machinery, construction machinery, port machinery, ship equipment and precision machinery radar and missile launchers and other equipment of large rotary device. But also according to the user's specific requirements design, development, production of special structure slewing ring bearings. Backing bearings are particularly thick outer bearing, when used to form a group to be mounted on stationary support roller shafts become.
