The structure and assembly dimensional accuracy and rotational accuracy of Inch tapered roller bearings for FAG are different from metric bearings. It is mostly used in imported machinery or industries with special needs. The external dimensions and tolerances are expressed in imperial units and are suitable for devices with imperial (usually inches) dimensions. For example, TIMKEN imperial tapered roller bearings sold by Yarui Company refer to tapered roller bearings whose external dimensions are measured in inches and originate from the British and American countries. Its structural types also include single row, double row, four row, etc., and its working performance is the same as the corresponding metric tapered roller bearing. Inch bearings express the outer dimensions and tolerances of the bearings in imperial units, and are suitable for devices with inch dimensions. Inch-size bearings are suitable for various inch-size industrial machines, small rotary machines, etc. The structure and assembly dimensional accuracy and rotational accuracy of Inch tapered roller bearings for FAG are different from metric bearings. Mostly used in industries with imported machinery or special needs. The counterpart is the metric bearing.
The inner and outer rings of Inch tapered roller bearings for FAG have tapered raceways, and tapered rollers are installed between the raceways. If the tapered surface is extended, it will eventually converge at a point on the bearing axis. Tapered roller bearings are mainly used to bear radial and axial combined loads, which are mainly radial loads. The axial load-carrying capacity of the bearing is determined by the contact angle. The larger the contact angle, the greater the axial load-carrying capacity. Tapered roller bearings are separable bearings. The inner ring with rollers and cage constitutes the inner component and can be installed separately from the outer ring.
This kind of bearing can limit the axial displacement of one side of the shaft or housing and does not allow the shaft to tilt relative to the housing hole. Under the action of radial load, additional axial force will be generated. Therefore, generally in the two supports of the bearing, the outer ring and inner ring of the bearing should be installed relative to each end surface.
The main uses of this type of bearings: automobile front wheels, rear wheels, transmissions, differentials, pinion shafts, machine tool spindles, construction machinery, large agricultural machinery, railway vehicle gear reduction devices, and rolling mill roll neck small reduction devices.
