Tapered roller bearings - Single-row - Inch series -- 28680/22

KOYO Tapered Roller Bearings 28680/22 bearings specification:

Tapered roller bearings consist of four independent components: the cone(the inner ring); the cup(the outer ring); the tapered roller(the rollingelements); and the cage(the roller retainers).

• This type bearings are designed to accommodate both radial and axial loads.
• Seprable design, i.e. the cone,consisting of the inner ring with roller and cage assembly, can be mountedseparately from the cup (outer ring).  
• Strong operation reliabilty and low sensitivity tomisalignment

• 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.
• Single row taper roller bearings can carry axial loads in one direction only. A radial load imposed on the bearing gives rise to an induced axial load which must be counteracted and the bearing is therefore generally adjusted against a second bearing. Some single row taper roller bearings are also avaible as matched paors in a face-to-face arrangement. These are specially manufacured so that when mounted immediately adjacent to each other, the predetermined axial internal clearance will be obtained and an even distribution of radial load achieved. Paired bearing arrangements are used where the load carrying capacity of a single bearing is inadequate, or the bearing arrengement must carry axial loads in both directions under given conditions of axial play.
• Taper roller bearings are generally separable, the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring).

  Tapered Roller Bearing apply mainly to the radial load to bear mainly of the radial and axial load, and the large cone angle tapered roller bearings can take to the axial load consisting mainly of joint load. Tapered roller bearings for the separation-bearing, and the outer ring of its components can be installed respectively, in the process of installation and use of the bearings may be adjusted radial clearance and axial clearance, the surplus can also be installed.

  Tapered roller bearing 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 pre-loaded mounting can be made.

Characteristic :
Taper roller bearings consists of two main units, a cup and a cone. The cup is on the outer race whereas the cone consists of inner race, the separator and compliment of taper rollers. The tapered rollers are guided by the high load on the inner race. The tapered roller bearings are manufactured with interchangeable cups and cone on the shaft separately.
These bearings are capable of carrying both the radial and axial loads and permit fine adjustment for end play. Greater care is required to ensure the proper alignment of bearings and maintenance of proper axial clearance is essential to avoid bearing failure. Due to more development in the design of the tapered roller bearings, these are also available with 2 rows and 4 rows.

These bearings can limit the axial displacement of either shaft or the housing in one direction. When only radial load, the auxiliary axial force can be formed. It is suggested that two of the bearings be prt in face to face or back to back arrangements in application and the cup and cones should be mounted relatively to their end surfaces.

Tapered roller bearings are mainly used on variable speed devices, differential mechanisms, pinion shafts, machine tool sindles, construction machines, large size agricultural machines, gear deceleration devices for railway vehicles, and the small deceleration devices for mill roll necks.

 1.Feature:

1)Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged.

2)Their rolling elements linearly come into contact with the raceways of inner ring and outer ring.

3)Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load and also can take the axial load only.

4)The larger the contact angle is, the higher the axial capacity can be loaded.
