Taper Roller Bearing NSK HR30208J Bearing 40×80×19.75mm Used In Elevator

Single Row Taper Roller Bearing NSK HR30208J Bearing is one kind of tapered roller bearing design. Its dimension is 40×80×19.75mm,weight is 0.42kg, the material are adopt high quality chrome steel,this design are separable. the bearing ring with the rollers and cage assembly can be separated from the other ring, so this kind of bearing are the same with single row cylindrical roller bearings .

For normal-angle tapered roller bearings, no contact angle symbol is used. Medium-angle tapered roller bearings are primarily used for the pinion shafts of differential gears of automobiles. Among those with high load capacity (HR series) , some bearings have the basic number suffixed by J to conform to the specifications of ISO for the cup back face raceway diameter, cup width, and contact angle. Therefore, the cone assembly and cup of bearings with the same basic number suffixed by J are internationally interchangeable.

Among metric-design tapered roller bearings specified by ISO 355, there are those having new dimensions that are different than the dimension series 3XX used in the past. Part of them are listed in the bearing tables. They conform to the specifications of ISO for the smaller end diameter of the cup and contact angle. The cone and cup assemblies are internationally interchangeable.

Taper Roller Bearings also have the other different design as follows

--Metric Single Row Taper Roller Bearings

--Inch Single Row Tapered Roller Bearings

--Double Row Taper Roller Bearings

--Four Row Taper Roller Bearings

--Hub bearing units for trucks

Design features Of Taper Roller Bearing HR30208J

Taper 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 taper 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 higher the axial load carrying capacity . An indication of the angle size is given by the calculation factor e; the larger the value of e, the larger the contact angle and the greater the suitability of the bearing for carrying axial loads.
