Taper roller bearings
Tapered roller bearings can be separated from the inner ring with roller cage components together and the outer ring can be installed separately. As amended by the roller and raceway contact at the contact line can reduce the stress concentration. The tapered roller bearing can withstand large radial and axial load. Tapered roller bearings can only pass one-way axial load, axial load in the opposite direction to pass on another with symmetrical installation of tapered roller bearings. The tapered roller bearings, the largest amount of single row tapered roller bearings. In the front wheels of cars in recent years, using the small size of the double row tapered roller bearings. Four tapered roller bearings used in a large cold and hot rolling mill and other heavy machinery Bore size:17 mm Outside diameter:40 mm Model number:30203 Precision rating:p0, p6, p5, p4, p3 z1, z2, z3, z4 Seals type:open Number of row:single row

Features 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. Applications Hob bearing of truck, shaft of large machine tool, wheel shaft box, large reducer, bearing of rollers of steel mill, etc. Classification 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 expression method of dimensions, bearing accuracy, symbols and definitions have been revised by iso.Our catalog has been revised in conformity with the jis and iso revisions. Basic load ratings have been revised with improvements in our materials and manufacturing techniques and according to iso 281/1-1997. The basic static load ratings are expressed in accordance with iso 76-1987
