As a world class bearing manufacturer

Iljin Group produces key auto parts and industrial bearings
and supplies them to customers worldwide.

  • Hub Unit Bearing
  • Chassis & Suspension
  • Powertrain

Hub unit bearing

Attached to the wheel of vehicle, this bearing supports the weight while also transferring the power.
There are two types, ball bearings and tapered roller bearings. Currently we are manufacturing all 1st, 2nd and 3rd generation
bearings and 3 out of 10 cars worldwide are running with ILJIN’s bearing.

  • Ball Bearing Gen 1

    It has simpler assembly process and increased endurance level and reliability compared to those of Bearing Generation 0. Mainly used for driving wheels, it is composed of integrated outer ring, a two-piece inner ring, balls, seals, cages and grease.

  • Ball Bearing Gen 2

    This bearing has a built-in hub unit which decreases the number of components and thus is made easier to assemble and have higher endurance and reliability. Mainly used for non-driven automotive applications, it is composed of an outer ring with a built-in integrated hub, two inner rings, balls, seats, cages and grease.

  • Ball Bearing Gen 3

    It has a hub made with an integral spline, so it improves ease of assembly. Increased durability and reliability. It is equipped with an ABS sensor and thus can be used for both driven and non-driven automobiles. It has integrated outer ring, inner ring integrated with hub, balls, seals, cages and grease.

  • Tapered Roller Bearing Gen 1

    It has simple assembly process and higher endurance level and reliability through unitizing. Mainly used for heavier vehicles such as SUVs and pick-up Trucks, and applying a more compact design than ball bearings is possible.

  • Tapered Roller Bearing Gen 2

    Manufactured with an integrated built-in hub, its assembly process has been made easier and it has higher endurance and reliability. It is usually used for non-driven automobiles, it is for heavier vehicles and MPV automobiles.

  • Tapered Roller Bearing Gen 3

    Its hub and splines are built-in, and has improved ease of assembly and increased durability and reliability. It is a bearing with an integrated hub that has improved the shortcomings of the 1st and 2nd generation bearing, and can be used for vehicles with various weights, including SUVs, Pick-up trucks and MPVs.

Chassis & Suspension

This component connects the body of the automobile to its wheels and
alleviates road impact transferred to the body by maintaining proper stiffness in all directions.
It adjusts the movement of vehicle appropriately to enhance the passenger’s comfort.


Bearings for transferring vehicles engine power support radial and axial loads from gears.
With growing demand for better fuel efficiency, ILJIN focuses on developing bearings with low radial torque,
and high wear resistance and rolling contact fatigue strength.

  • Double Row Large Angular Contact Ball Bearing For Axles

    A bearing attached to shaft, a component of car axles and gear sets.

  • Double Row Angular Contact Ball Bearing with Flange type

    A flanged typed ACBB bearing that attaches to automatic transmissions.

  • Single Row Tapered Roller
    Bearing with a Steel Cage

    A tapered roller bearing that supports high radial and axial loads and lowered thermal radiation and wear by applying high-strength steel cage through design optimization.

  • Single Row Tapered Roller
    Bearing with a Plastic Cage

    A low-torque tapered roller bearing that has lowered torque applied compared to that of existing steel cage by applying optimized designs to enhance lubrication performance.

  • High Speed Deep
    Groove Ball Bearing

    A bearing used for precision machines with high speeds, precision measuring machines, high-speed motors, automotive T/M and axles and aerospace.

  • Ball Ramp

    A bearing used for clutch application of vehicles. It transforms rotational motion to straight line motion and operates clutch.
