Product Description

A Single-row Tapered Roller Bearing Ring is designed to accommodate both radial and axial loads simultaneously. The tapered geometry of its inner and outer raceways and rollers allows it to manage combined loads efficiently. Compared with double-row types, the single-row structure is more compact and lightweight—ideal for applications requiring medium-to-high load capacity where axial space is limited.

Our forged inner and outer rings for single-row tapered roller bearings are manufactured from high-carbon bearing steel through precision ring-rolling and heat treatment processes.
These Bearing Rings feature dense internal structure, high hardness, and superior wear resistance, ensuring smooth rotation, low noise, and long service life.
They are ideal for applications requiring high load capacity and stability, such as wind turbine main shafts, gearboxes, heavy machinery, mining and metallurgical equipment, and marine propulsion systems.

Applications

Large-diameter single-row tapered roller bearing rings are widely used in high-load, high-precision rotating systems, including:

Wind Power Generation:
As tapered roller bearing rings for wind turbines, used in main shaft systems, gearbox supports, and planetary gear assemblies for large-scale turbines.
Industrial Power Transmission:
Applied in heavy machinery, mining equipment, and metallurgical gearboxes where high torque and stiffness are essential.
Marine Propulsion Systems:
Providing reliable torque transmission under harsh marine environments, working alongside forged shafts and forged discs.
Construction & Mining Equipment:
Serving as key bearing components in excavators, cranes, and rolling mills requiring high axial and radial load capacity.

Our Alloy Steel Shrink Disc delivers mechanical locking performance for the heavy‑duty applications. Leveraging Liaoyuan’s ring‑rolling technology and custom‑design capabilities, these shrink discs provide backlash‑free torque transmission with superior strength, reliability, and service life. Whether you’re driving wind‑power gearboxes, heavy‑machinery shafts, or hoisting systems, choosing our solution ensures a perfectly engineered fit .
