30302 Inch Tapered Roller Bearing

The imperial tapered roller bearing main use: automobile front wheel, rear wheel, transmission, differential, small gear shaft, machine tool spindle, building machinery, large agricultural machinery, railway vehicle gear speed reducer, rolling mill roll neck small reduction gear.

Tapered roller bearing inner and outer ring of taper rolling way, between race with tapered roller. If the conical surface extension, and eventually converge on the bearing axis. Tapered roller bearing is mainly used to bear to mainly consisting of radial load, axial load. Bearing the axial bearing capacity is determined by contact Angle, the larger the antenna, the greater the axial bearing capacity. Tapered roller bearing for separating type bearing, within the inner ring with roller and cage components, can be installed separately from the outer ring. This kind of bearing can limit the shaft or the shell side of the axial displacement, are not allowed to have tilted axis relative to the shell hole. Under the effect of radial load, can produce additional axial force, therefore, generally in the bearing of the two bearing, bearing outer ring and inner ring with the face should be relative to the installation. Main use: these bearings are of automobile front wheel, rear wheel, transmission, differential, small gear shaft, machine tool spindle, building machinery, large agricultural machinery, railway vehicle gear speed reducer, rolling mill roll neck small reduction gear. U production classification metric, inch of single, double, four row tapered roller bearing structure 1. Restrict single row tapered roller bearing the bearing shaft or a direction of the shell axial displacement, carry axial load in one direction. Under the action of radial load, axial force status of the bearing should be balanced. Two bearings should be face to face or back to back. 1. Double row circular cone roller bearings of the tapered bearings in bear radial load at the same time it can be subject to bi-directional load. Can be within the scope of the bearing axial clearance limit shaft or shell two-way axial movement. 1. The four row tapered roller bearing of the bearing performance and double row circular cone roller bearings basic same, but the than double row tapered roller bearing radial load is bigger, limit rotational speed is a bit low, mainly used in heavy machinery, such as rolling mill, etc. 1. More than double seal, four row circular cone roller bearings provide long life, sealed double, four row circular cone roller bearings. To personalized new design of bearing, change the sealed bearing with traditional design method, by adopting the combination of sealing and dustproof new type sealing structure, improve the sealing effect, improve the sealing performance. More sealed double bearings, four row circular cone roller bearings with open structure, compared life increased by 20% ~ 40%; Lubricant consumption reduced by 80%. Sealed bearing with more rear code XRS logo. ◈ size range of circular cone roller bearings basic size has been listed in size data table, single row taper roller bearings, inner diameter size range: 20 mm to 1270 mm diameter size range: 40 mm to 1465 mm width size range: 15 mm to 240 mm double row circular cone roller bearings: inner diameter size range: 38 mm to 1560 mm diameter size: 70 mm to 1800 mm width size range: 50 mm to 460 mm range of four row tapered roller bearing inside diameter size: 130 mm to 1600 mm
