Cylindrical Roller Thrust Bearings / Cage Assembly

Cylindrical Roller Thrust Bearings / Cage Assembly

Core Features

  • Pure Axial Load Support: Unlike radial cylindrical bearings, these are designed specifically to support heavy axial loads in a single direction.
  • High Load Density: The use of cylindrical rollers instead of balls provides a larger contact area, allowing for much higher load ratings in a compact axial space.
  • Exceptional Rigidity: These bearings are very stiff and produce minimal elastic deformation under heavy pressure, ensuring precise axial positioning.
  • Modular Component Design: The product typically consists of a cylindrical roller and cage thrust assembly, a shaft washer, and a housing washer, which can often be purchased or installed separately.
  • Low Section Height: Provides a high power-to-weight ratio, making it ideal for applications where axial space is restricted but load requirements are extreme.

At Kriloha Ltd., we understand that “Axial-Integrity” is the foundation of high-torque rotating systems. Our Cylindrical Roller Thrust Bearings and Cage Assemblies are our engineered answer for “Maximum-Thrust-Resistance” and “High-Precision-Alignment.” As a premier provider of industrial components, Kriloha has developed a thrust series that balances mechanical invincibility with the design agility required for the world’s most demanding machinery.

The engineering of our thrust series is based on Uniform Stress Distribution. By utilizing precision-profiled rollers within a high-strength cage, we ensure that axial forces are spread evenly across the raceways, preventing the “point-loading” failure common in lesser designs. At Kriloha, we verify that our cage assemblies—whether machined brass or high-performance steel—are engineered to minimize friction and heat generation at high loads. This creates a “Rigid-Resilient” support system that maintains absolute stability even under fluctuating pressure.

Manufacturing these assemblies involves strict Parallelism and Surface-Finish Verification. We ensure that the washers and rollers are super-finished to facilitate an optimal lubricant film, extending the service life of your equipment. Whether you are maintaining a massive industrial extruder or a critical offshore swivel, Kriloha Thrust Bearings provide the mechanical durability your facility demands. By choosing Kriloha Ltd., you are investing in a “High-Load” technology that secures your most mission-critical axial assets.

Primary Use Cases

  • Heavy-Duty Gearboxes: Managing the intense axial thrust generated by helical or bevel gears.
  • Crane Hooks and Swivels: Providing smooth rotation under the massive vertical loads of suspended cargo.
  • Extrusion Machinery: Supporting the screw-drive shafts in plastic and metal extruders that face high constant pressure.
  • Oil and Gas Drilling Equipment: Essential for the rotary tables and top drives of drilling rigs.
  • Industrial Turntables: Ensuring fluid motion for heavy rotating platforms and indexing tables.

Frequently Asked Questions

Frequently Asked Questions (FAQs)
1. Can a cylindrical roller thrust bearing handle radial loads?
No. These bearings are designed to handle axial (thrust) loads only. Any significant radial load must be supported by a separate radial bearing.
2. What is the advantage of buying just the “Cage Assembly”?
In many compact designs, the rollers and cage can run directly against the hardened surfaces of the machine components (acting as raceways), saving the space and cost of separate washers.
3. Are these bearings suitable for high-speed applications?
Cylindrical roller thrust bearings are generally limited to lower speeds compared to ball thrust bearings due to the sliding friction that occurs at the ends of the rollers.
4. Can they handle misalignment?
No. These bearings are very sensitive to angular misalignment between the shaft and the housing. Precise machining of the mounting surfaces is critical for long service life.
5. Do they support thrust in both directions?
Standard assemblies support thrust in one direction. For bi-directional thrust, a double-acting assembly (incorporating two cage assemblies and three washers) is required.
