Introductions :
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 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 larger , 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.

Taper roller bearings Physical Characteristics:
(1).Taper roller bearings have tapered inner and outer ring raceway between which tapered rollers are arranged.
(2).Three projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes taper roller bearings particular accommodation of combined (racial and axial) loads.
(3).The axial load carrying capacity of the bearings is largely determined by the contact angle.
(4).Taper roller bearing has the logarithmic contact profile that provides for optimum stress distribution over the roller/raceway/contacts.
(5).The special design of the sliding surfaces of the guide flange and large roller ends considerably promotes lubricant film formation in the roller.
Taper roller bearings applications :
Excellent alignment compensation
Suitable for large radial loads
Low to medium speed ratings
Application examples: widely used in automotive, truck, rolling mill, mining, farming machine, construction machine, general machine, etc.
