SKF Taper Roller Bearing 30214 J2/Q
Taper Roller Bearing:
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the contact angle; the large contact angle. the higher the axial load carrying capacity. Tapered roller bearings are generally separable, i.e. the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the (out ring).
We can provide maiy kind of tapered roller bearings including metric and imperial standard in different occasions:
Single row: Consist of a innerring with single race, a outer ring with single race, a steel cage and a set of taper roller.
Single row paired: Consist of two sets of single row tapered roller bearings and one or two spacer. It has three kinds of configurations.
Doubel Rows: Consist of outer ring with two races and two subassemblies which are consist of rollers and cages. The main purpose is applicable of gearboxes, hoisting equipment, rolling mills and machines used in the mining industry, e.g. tunnelling machines.
Four-row: It has two configurations which are called as TQO and TQI. TQO consist of two rows inner rings, subassemblies which consist of rollers and cages and one inner spacer, one outer spacer, one outer ring with two single races, two outer rings with single race.
TQI consist of two ring with double races, one outer spacer, two rows inner rings subassemblies which consist of rollers and cages and two single inner rings which rollers and cages.
Gradient angle allowed:
Tapered Roller Bearing does not allow axis relative shell holes are inclined, the laregest value of its gradient angle can not be exceed.
The clearance:
The clearance of single row tapered roller bearings can only be obtained after mounting and is determined by adjustment of the bearing per consumer's requirement. The axial clearance of paired single row is in sheet one. The radial clearance of two rows tapered roller bearings and four rows tapered roller bearing are in sheet two.
