3. Technical Description

The NTN 4T-02474/02420 is a high-quality, single-row tapered roller bearing designed to carry combined loads, meaning both radial and axial forces. The conical raceways and tapered rollers ensure:

• Excellent load distribution
• High rigidity
• Reliable performance under demanding conditions

Because of its cup-and-cone, separable design, the bearing is:

• Easy to mount and dismount
• Convenient for applications requiring periodic inspection or replacement

Single-row tapered roller bearings are generally used in pairs, mounted in mirror-image arrangements to support axial loads in both directions. They can be mounted in:

• X-arrangement (crossed)
• O-arrangement (face-to-face)
• Tandem arrangement (to share axial load in one direction)

4. Typical Applications

• Automotive differentials and axles
• Transmissions and gearboxes
• Industrial gear drives
• Agricultural and construction machinery
• General power transmission where combined loads are present

5. Key Advantages

• Premium Japanese NTN quality
• High radial and axial load capacity
• Separable cup and cone → easier handling and mounting
• Standardized dimensions → interchangeable with other 02474/02420 sets
• Suitable for demanding industrial and automotive applications
