Single-Row Tapered Roller Bearings

The single-row tapered roller bearing is the most basic and most widely used tapered roller bearing. The outer ring and the inner ring can be separated. Therefore, any outer ring or inner ring that is in accordance with the ISO shape and size standards can be interchangeable with their counterparts made by other manufacturers. This type of tapered roller bearings is often installed in pairs. The clearance and bearing capacity can also be adjusted as required when the bearings are installed.

Our single-row tapered roller bearing is most frequently used in rear axle hubs of automobiles, spindles of large machines, speed reducers with high powers, trolley wheels of conveying apparatuses, etc.
