Tapered Roller Bearings
overview
Tapered Roller Bearings
KG Tapered Roller Bearings are specifically designed to handle combined radial and axial loads, making them ideal for applications that experience both types of forces simultaneously. With their conical geometry and high load-bearing capacity, they are a trusted choice for heavy-duty, high-performance industrial and automotive applications.
Features
- Handles Combined Loads : The tapered raceways allow these bearings to support both radial and axial loads efficiently—especially in one direction.
- High Load-Carrying Capacity : The line contact between rollers and raceways enables excellent support under heavy and shock loads.
- Adjustable Clearance : Axial clearance can be adjusted during mounting, allowing precise control over performance and preload.
- Separable Components : The inner (cone) and outer (cup) rings can be mounted separately for ease of assembly and inspection.
- Long Service Life : Manufactured with high-quality steel and precision engineering for durability and reliability under extreme conditions.
Application
- Automotive Wheel Hubs and Transmissions
- Gearboxes and Differentials
- Agricultural Equipment
- Mining and Construction Machinery
- Heavy-Duty Trucks and Trailers
- Steel Mills and Industrial Drives
- Railway Axle Boxes
Why Choose KG Tapered Roller Bearings?
KG Tapered Roller Bearings offer superior load handling, precise alignment and long-lasting performance even in harsh environments. Trusted across industries for their consistent quality, cost-efficiency and global support, these bearings are an excellent solution for demanding mechanical systems where strength and reliability are critical.
Double Row Tapered Roller Bearings
KG Double Row Tapered Roller Bearings are engineered to support both radial and axial loads in two directions, making them ideal for applications that require high load capacity and stability in both radial and axial directions. These bearings are designed with two rows of tapered rollers, allowing for greater load distribution and improved performance in heavy-duty and high-stress applications.
Key Features
- Dual Load Capability : Designed to handle both radial and axial loads in two directions, providing a versatile solution for applications under mixed load conditions.
- High Load-Carrying Capacity : The two-row design increases the bearing’s load capacity compared to single row bearings, making them suitable for heavy-duty applications.
- Compact Design with Greater Stability : The double-row configuration allows for a more compact bearing arrangement, saving space while offering superior stability under dynamic loads.
- Separable Components for Ease of Assembly : The inner and outer rings can be disassembled, making installation, inspection, and maintenance easier.
- Long-Lasting Durability : Constructed with high-quality materials and precision engineering, these bearings ensure extended service life and reliability in demanding conditions.

Single Row Tapered Roller Bearings
Single row tapered roller bearings are engineered to support both radial and axial loads simultaneously. Their raceway geometry is designed so that the projection lines converge at a single point on the bearing axis, ensuring smooth rolling motion. This precise alignment minimizes frictional resistance, enhancing operational efficiency and extending bearing life.
Key Features
- Combined Load Support : They can handle both radial and axial (thrust) loads simultaneously, making them suitable for applications with combined loading conditions.
- Converging Raceway Geometry : The raceway angles are designed to converge at a single point on the bearing axis. This ensures optimal load distribution and smooth rolling motion.
- Low Friction and Long Life : The precise alignment minimizes friction, improving efficiency and extending the bearing’s service life.
Application
- Automotive Transmissions and Wheel Hubs
- Gearboxes and Differentials
- Construction and Mining Equipment
- Agricultural Machinery
- Machine Tool Spindles
- Conveyor Systems
- Pumps and Compressors
Four Row Tapered Roller Bearings
Four-row tapered roller bearings can accommodate combined (radial and axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.
Key Features
- Support for Combined Loads : Designed to accommodate both radial and axial loads, making them ideal for heavy-duty applications.
- Optimized for Low to Moderate Speeds : Specifically engineered to operate efficiently at low to moderate rotational speeds.
- Application-Specific Design : Primarily used in work roll positions in rolling mills, where high load capacity and durability are essential.
Application
- Rolling Mills
- Heavy Industrial Machinery
- Gear Drives and Large Shafts
FAQ's
What are radial loads and axial loads?
Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads
How do deep groove ball bearings (DGBBs) differ from single-row angular contact ball bearings?
While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.
What are the differences between open, sealed, and shielded deep groove ball bearings?
Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings.
NSK uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
