slewing bearings is a kind of large-size bearing with special configuration which can bear axial load, radial load and tilting moment. generally, a slewing bearing has mounting holes, lubricating holes and sealing system which can meet different needs of different machines under different working conditions. our slewing bearings include the following types: 4 point contact ball slewing bearing; double-row angular contact ball slewing bearing; crossed cylindrical roller slewing bearing; three-row cylindrical roller slewing bearing; ball and cylindrical roller combined slewing bearing. these bearings can be divided with no-gear, external gear and internal gear. slewing bearings can meet different needs of different machines under different loads as per their types. 4 point contact ball slewing bearing can carry higher dynamic loads; crossed cylindrical roller slewing bearing can carry higher static loads; the preload of crossed tapered roller slewing bearing can make it better support rigidity and higher rotation accuracy; three-row cylindrical roller slewing bearing can carry large load.

Tapered roller bearings, the outer ring has a tapered raceway, raceway with tapered roller between. If an extension of conical surface, and ultimately converge on the bearing axis point. Tapered roller bearings are mainly used to bear radial load mainly consisting of radial and axial load. The axial load bearing capacity of the decision by the contact angle, the greater the reach, the greater the axial load capacity. Tapered roller bearings for the separation of bearings, roller and cage with the inner ring in the inner components separately with the outer ring installation. This kind of bearing shell side may limit the axis or axial displacement, does not allow a tilt axis relative to shell hole. In the radial loads, will produce additional axial forces, therefore, generally supported in two bearings, the bearing outer ring and inner ring with the face should be relatively installation. The main purpose of such bearings: Automotive front, rear, transmission, differential, pinion shaft, spindle, construction machinery, large-scale agricultural machinery, railway vehicles, gear reduction rolling mill roll neck small deceleration devices. Structure Single row tapered roller bearings - Metric and Inch Double row tapered roller bearings - Metric and Inch Single row tapered roller bearings Such bearings can only limit the shell axis or axial displacement in one direction, a direction under axial load. Under the action of the radial load, axial force generated by the bearing must be balanced. Face to face or back to back two bearings should be used. Double row tapered roller bearings Such tapered bearings, while the radial load can withstand two-way axial load. In the bearing axial clearance or shell within the limits of the bi-axial shaft movement. Size range Tapered roller bearings RNB basic dimensions are listed in the data table size, Single row tapered roller bearings: Diameter size range: 15mm ~ 260mm Diameter size range: 42mm ~ 400mm Width range: 14mm ~ 87mm Double row tapered roller bearings Diameter size range: 15mm ~ 260mm Diameter size range: 35mm ~ 420mm Width range: 25mm ~ 200mm Competitive Advantage High-precision roller - guide on the featuress to ensure that the pure rolling Optimal rib design - concentric and maintain accurate positioning Increased exposure to taper - more axial load.
