Thrust Roller Bearings
overview
Thrust Roller Bearings
Thrust roller bearings, available with cylindrical, tapered, or spherical rollers, are designed exclusively for axial load support. KG’s thrust roller bearings provide exceptional axial rigidity and are ideal for handling heavy loads. Standard designs feature machined brass cages, ensuring durability and reliable performance.
Features
- Exclusive Axial Load Support: Designed specifically to handle heavy axial loads, not radial loads.
- High Axial Rigidity: Provides exceptional stiffness for precise axial positioning under load.
- Durable Machined Brass Cages: Ensures reliable performance and long service life in demanding conditions.
Applications
- Heavy-Duty Gearboxes
- Marine Propulsion Systems
- Steel and Paper Mills
- Vertical Pumps and Compressors
- Crane Hooks and Lifting Equipment
- Machine Tool Spindles
- Oil Drilling Rigs and Equipment
- Rotary Tables and Industrial Turntables
Product List
Cylindrical Roller Thrust Bearings
Cylindrical roller thrust bearings are designed solely for axial load support, offering exceptional axial rigidity and suitability for high-load applications. They typically feature machined brass cages for enhanced durability and performance.
Key Features
- High Load & Rigidity: A simple yet robust design ensures excellent axial load capacity and structural rigidity.
- Best for Low Speeds: While not ideal for high-speed use due to roller sliding, their compact, cage-guided structure enhances stability in low-speed applications.
Applications
- Gearboxes and Speed Reducers
- Machine Tool Spindles
- Electric Motors and Generators
- Oil and Gas Drilling Equipment
- Pumps and Compressors
- Steel and Paper Mill Equipment
- Railway Axle Boxes and Traction Motors
- Wind Turbines and Industrial Fans
Tapered Roller Thrust Bearings
Tapered roller thrust bearings come in two types: TT and TTF.
TT bearings have a rib on the housing washer and can accurately guide the shaft in the radial direction.
Conversely, TTF bearings have no rib on the housing washer and can tolerate some eccentricity during operation.
 Features
- High Axial Load Capacity: Specifically designed to support very heavy axial loads, even under shock and impact conditions.
- Accurate Load Distribution: The tapered geometry ensures uniform load distribution, enhancing stability and service life.
Applications
- Rolling Mills (Backup Roll Assemblies)
- Heavy-Duty Gearboxes
- Marine Propulsion Systems
- Mining and Construction Equipment
- Oil and Gas Drilling Machinery
- Vertical Shaft Applications
- Steel and Paper Mill Equipment
- Large Industrial Presses
Spherical Roller Thrust Bearing
Spherical roller thrust bearings are self-aligning, allowing them to compensate for mounting misalignment and shaft deflection.
The E-type design enhances load capacity with a pressed steel cage, while machined brass cages are recommended for horizontal shafts and high-speed applications.
Due to the complexity of their internal components, oil lubrication is preferred even at low speeds to ensure optimal performance.
Standard cage materials typically include machined brass for durability and efficiency.
 Features
- Self-Aligning Design: The spherical raceway of the housing washer allows for automatic alignment, compensating for misalignment.
- High Load Capacity: Designed to handle substantial axial loads with the ability to support limited radial loads under axial force.
Applications
- Hydraulic Turbines and Water Wheels
- Marine Propulsion and Offshore Equipment
- Gearboxes and Extruders
- Pulp and Paper Processing Machines
- Cement and Mining Equipment
- Steel Mill Roll Necks and Continuous Casting Machines
- Vertical Pumps and Compressors
- Heavy-Duty Industrial Fans and Blowers

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.
