Double Row Tapered Roller Bearings

At Kriloha Ltd., we recognize that extreme industrial challenges require “Multi-Point” stability. Our Double Row Tapered Roller Bearings are our engineered answer for “High-Torque” and “High-Load” reliability. As a premier provider of industrial components, Kriloha has developed a range that balances mechanical invincibility with operational agility.

The engineering of our double row series is based on Structural Symmetry. By utilizing two rows of rollers, we create a balanced load distribution that prevents uneven wear on the raceways. At Kriloha, we offer multiple configurations—including TDO (One double outer race and two single inner races) and TDI (One double inner race and two single outer races)—to match the specific housing and shaft requirements of your equipment. This creates a “Rigid-Resilient” support system that remains stable under the most punishing industrial duty cycles.

Manufacturing these bearings involves strict Pre-Set Clearance Calibration. We verify that every assembly is matched to precision standards, ensuring that the internal geometry is optimized for heat dissipation and load carrying. Whether you are overhauling a massive gear drive or a critical rail axle, Kriloha Tapered Roller Bearings provide the mechanical durability your facility demands. By choosing Kriloha Ltd., you are investing in a “High-Capacity” technology that secures your highest-value rotating assets.

Primary Use Cases

Heavy-Duty Gear Drives: Used in industrial reduction gears where high torque and reversing thrust loads are present.
Railway Axle Boxes: Supporting the immense weight and lateral forces of freight and passenger rail cars.
Rolling Mill Work Rolls: Managing the high radial forces and shock loads in steel and aluminum processing facilities.
Hoisting Equipment: Found in large cranes and winches where stable, high-capacity rotation is mission-critical.
Automotive Transmissions: Employed in heavy-duty commercial vehicle transmissions to manage complex gear mesh forces.

Frequently Asked Questions

Frequently Asked Questions (FAQs)
1. What is the advantage of a double row over two single-row bearings?
A double row bearing is usually factory-matched and pre-adjusted, reducing installation errors and ensuring a more compact design with higher rigidity.
2. Does a double row bearing require a spacer?
Depending on the design (TDO or TDI), a spacer may be used between the rings to set the exact internal clearance or preload. Kriloha provides these as precision-ground matched sets.
3. Can these bearings handle misalignment?
While very rigid, they have limited tolerance for misalignment. Precise shaft and housing alignment is essential to prevent edge loading on the rollers.
4. Are they available in both Metric and Inch series?
Yes. Kriloha supplies double row configurations in both standard Metric (ISO) and Inch (ABMA) dimensions to fit global machinery.
5. How are they lubricated?
They can be grease or oil lubricated. Most double row housings include specialized lubrication holes and grooves in the outer or inner rings to ensure both rows of rollers receive even cooling and lubrication.
