IKO creates a range of crossed roller bearings that can simultaneously support moment, thrust, and radial loads.
Crossed roller bearings with high stiffness provide a sturdy, one-piece design for maximum precision.
A two-piece outer ring that is fastened together in standard crossing roller bearings prevents separation during shipping and installation.

3. The different types of IKO bearings?

Here are the different types of IKO bearings:
    1.   Crossed Roller Bearings

These small bearings have rollers that are diagonally crossed between the inner and outer rings.
Options for roller guides include a cage or divider in addition to a full complement layout.
For high-speed rotation, the cage and separator designs both provide a low coefficient of friction.
  • Mounting Holed Type
High-stiffness crossed roller bearings with mounting holes have mounting holes on both the inner and outer rings for simple installation. For maximum rigidity and accuracy, an inseparable design combines the inner and outer rings into a single structure. The sizes of the shafts range from 10 to 90 mm.
  • High Rigidity
For high rigidity, an inseparable design combines the inner and outer rings into one structure. Separators between the cylindrical rollers, suited for high rotating speeds, provide smooth spinning. The sizes of the shafts range from 20 to 300 mm.
  • Standard
Available in caged and full complement variants, shaft diameters range from 30 to 250 mm. There are CRB and CRBC models with shaft diameters up to 800 mm.
  • Slim
Slim crossed roller bearings have a narrow width and a tiny outside diameter compared to the internal diameter. 50 to 200 mm is the range of shaft diameters. Available in full complement, separation, and caged forms.
  • Super Slim

    1.   Shell Type Needle Roller Bearings

IKO makes a variety of radial needle roller bearings to accommodate various machine profiles and application requirements.
These include machined-type needle roller bearings, shell-type bearings, and needle roller cages for use both externally and internally in engine connecting rods.
Depending on the configuration, shell-type needle roller bearings are thin, light-motion parts that can support either heavy loads or fast speeds.
With the lowest sectional height of any needle roller bearing, a streamlined profile is made possible by an outer ring constructed of high-strength steel.
There are two varieties of shell-style bearings: caged and full complement:
  • The precise needle rollers in caged bearings for high-speed rotation are precisely guided by a cage and thrust rings.
  • Press-fit full complement bearings for large loads and low-speed rotation into the housing without the need for axial positioning devices, providing a cost-effective solution for mass-produced goods.
    1.   Machined Type Needle Roller Bearings

Low sectional heights and high load ratings are characteristics of our machined-type needle roller bearings.
These parts are also excellent for housings made of light alloys because of their extremely robust outer ring. There are three different types: guided, caged, and solid-lubricant type.
These bearings with or without inner rings are options in design. Shafts serve as the raceway in bearings without inner rings, which have streamlined, small footprints.
    1.   Needle Roller Bearings With Separable Cage

5. Advantages and disadvantages of IKO bearings?

These are the advantages of IKO bearings:
  • The gearbox receives no or less stress, relies on the torsion arm to sustain less distortion, and the assembly is straightforward.
  • The suitable range of bearings is wider, and the bearing capacity can be enhanced by extending the space between the bearings.
  • The shaft and bearing have a smaller diameter and are less expensive.
  • The overall rigidity of the shaft system is quite high due to the elimination of the axial clearance, and the dynamic load has little impact on it.
  • The transmission chain is small, the main shaft is short, and the nacelle can be made to be relatively short in length.
  • As a result of the bigger diameter and shorter shaft of IKO bearings, the total stiffness of the shaft system is high and the amount of structural deformation brought on by the load is minimal.
  • IKO bearings are simple to grease because they may be lubricated from both sides.
  • Because the gearbox and the main shaft are integrated, the main bearing can be lubricated with oil, reducing pollution from the lubrication of the main shaft, improving bearing lubrication, and extending bearing life.
The disadvantages:
  • The location of the hub in the axial direction is poor, and the axial clearance is rather large.
  • The main bearing does not experience any pre-tightening force, and the axial displacement following a load is considerable.
  • A single roller might not revolve at the same time due to the absence of a pre-tightening force, resulting in slippage, which will cause a very high peak load.
  • The load has a significant impact on the shaft despite its modest size.
