Tapered roller bearings comprise solid inner and outer rings with tapered raceways and tapered rollers with cages. The bearings are not self-retaining. As a result, the inner ring together with the rollers and cage can be fitted separately from the outer ring. Tapered roller bearings can support axial loads from one direction as well as high radial loads. They must normally be axially adjusted against a second bearing fitted in a mirror image arrangement.
|
|
Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged, their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial ) load.
Our tapered roller bearings have single, double and four-rows. we manufacture both metric and inch size tapered roller bearings.

Single-row tapered Roller Bearings are the most widely used tapered roller bearings. They have a high radial capacity and a thrust capacity of about 60% of radial capacity.
The exact percentage depends on the contact angle of the tapered roller bearing. Variations within the type include tapered bores for frequent removal, pin cages and hollow rollers for higher capacity, and steep roller angles for higher thrust capacity.

Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the certerline of the bearing. Due to this design feature,rollers move along the center of theraceway surfaces. The tapered rollers are guided by the compound force of the inner and oter raceway surfaces which keep them pressed up against the large rib on the raceway surfaces which keep them pressed up against the large rib on the inner ring.A large variety of these bearings,including single,double,and four row arrangements,are in use both in metric and inch series.

Tapered roller bearings are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Along with metric series bearings, inch series bearings are also available. This type of bearing is suitable for applications that involve heavy or impact loading.
Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers which are profiled to distribute the load evenly. They have high radial and axial (thrust) load capacities at low to intermediate speeds. Tapered roller bearings are available in single-row, two-row and four-row designs. With single-row bearings, the thrust load capacity is about 60% of the radial capacity. Double-row bearings have a greater radial load capacity and can handle thrust loads from both directions. The rollers can be configured so that the contact lines to the races converge or diverge towards the axis of rotation. Diverging double-row bearings increase the rigidity of the shaft mounting, but converging bearings do not. Other configurations for double-row bearings feature a single outer ring and two inner rings, or two outer rings and a single inner ring. Four-row tapered roller bearings consist of four rows of alternating converging and diverging rollers.

Single row tapered roller bearings are separable radial bearings:
- Suitable for high radial loads and thrust loads (in one direction)
- Take up tilting moments
- When paired, can take up thrust loads in both directions
- Standards: DIN 616, DIN 720
- Series: 30200, 30300, 31300, 32000, 32200, 32300, 33000, 33100, 33200
- Application examples: gear boxes, pumps, compressors, etc.
Tapered roller bearings, IKOS design are sealed, ready-for-use, non-separable bearing units.

The inner and outer ring raceways and rollers of this type of bearing are made with a taper so that the planes of the surfaces of the raceways and roller axis meet at a point. The rollers are guided by the cone (inner ring) back-face rib. A single-row Tapered roller bearing can support a combined radial and axial load. If either a radial load or bi-directional axial load is to be carried, a pair of bearings must be used in a "face-to-face" or "back-to-back" mounting.
Tapered roller bearings are separable into the components: outer ring, inner ring and roller assembly. The non-separable inner ring and roller assembly is called the "cone", and the outer ring is called the "cup". Internal clearance is established during mounting by the axial positioning of the cone relative to the cup. This bearing type can be used in a preload situation to obtain higher rigidity and better running accuaracy of the shaft.

RKB taper roller thrust bearings have separable parts: shaft washer, housing washer and rolling element assembly.
RKB program includes the single direction type, the double direction type and the screw-down special type.
RKB T.R.T bearings are manufactured in two constructive versions.
The rollers are radially guided by the rib of one washer (suffix ZB).
These bearings can also be produced in the version without the cage (suffix V).
The most common series are T, TK and 351 type.
Bearings made of case hardened carburizing alloy steels can be also produced.
RKB bearings are used in the rolling mill applications associated.
RKB produces double direction taper roller thrust bearings in two constructive versions, either with central plane shaft washer and taper raceways in both housing washers or with both plane housing washers and taper raceways in the central shaft washer.
A special sleeve is arranged, so no special adjustment of the bearing is required.
As the double direction taper roller bearings are usually mounted with loose fit on the roll neck, the shaft washer is normally provided with one or two locating slots that, engaged with key-way or similar devices, prevent the shaft washer from rotating on the seating.
The most common series are 350, 351, 353 and TTK type.
RKB screw-down bearings are a special design of the single direction taper roller thrust bearings used for rolling mill arrangements.
They are generally produced with case hardened carburizing alloy steels and with full complement of long rollers of large diameter.
The dimensions of taper roller thrust bearings are not standardized.
The main boundary dimensions are produced according to ISO 199/1979

Tapered roller thrust bearings allow for a very compact bearing arrangement which can carry very heavy axial loads, and provide high shock-load resistance in a variety of applications.
We produce single direction tapered roller thrust bearings and double direction tapered roller thrust bearings. The screw-down bearings constitute a special design of single direction tapered roller thrust bearing.
