a?high speed, high precision
b?high rigidity, stand impact and vibration
c?can withstand big axial load
This bearing is suitable to bear composite load of axial load and radial load. Normally radial load is predominant but for great taper angle bearing the axial load could be predominant.
Taper roller bearing is a separable bearing. Its outer ring can be mounted individually from the unit of inner ring, cage and rollers. Its radial and axial internal clearance can be adjusted during installation; even can be a interference installation. For taper roller bearing stamped steel cage is common selection. For large size bearing, welded steel cage or pin-assembled cage is used.
Hob bearing of truck, shaft of large machine tool, wheel shaft box, large reducer, bearing of rollers of steel mill, etc.
Tapered roller bearings are in many designs and sizes to match their many uses. These can be grouped as follows
single row tapered roller bearings;
paired single row tapered roller bearings;
double row tapered roller bearings;
four-row tapered roller bearings.
Single-row tapered roller bearings accommodate radial and axial loads (in one direction). For technical reasons, they are always positioned against a second tapered roller bearing in a mirror arrangement.
Double-row tapered roller bearings accommodate radial and axial loads (in both directions) and are available in metric or inch sizes. The axial play of the bearing pair is determined during bearing production. There are numerous applications in industry and in the automotive sector.
Four-row tapered roller bearings are used in rolling mills for the steel and non-ferrous industry sectors. These bearings are designed for extremely high radial and axial loads as well as for high speeds and impact loads and are used in extremely unfavorable ambient conditions such as high temperatures, water and contamination. With the new Performance series for rolling mills, costs can be significantly reduced from a TCO perspective.
[The factors that influence bearing performance and service life include but are not limited to the following:]
a.roller end/ flange contact area
c.consistency of profiles and roller size
