Descriptions of Heavy machinery bearing 2559/23

Taper roller bearings are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

Tapered bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.

Taper roller bearings are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.
The tapered roller bearings mainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring’s raceway. The bigger the contact angle is, the greater the capacity will be.

product advantages	(1).High precision rollers (lead to centering function and ensure pure rolling)
	(2).optimize the design of flange (keep precise copper core and position)
	(3).better contact with cone angle (more sustain of axial load)
design feature:	1.Easily installation. High radial and axial rated load.
design feature:	2.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 cup.

Physical Characteristics of Heavy machinery bearing 2559/23

(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 bearing 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.
