Four Row Tapered Roller Bearings
Four row tapered roller bearings are a type of bearing with high precision and high load-carrying capacity, featuring four rows of tapered rollers arranged between the inner and outer rings. These bearings are featured by strong load-carrying capacity, good rigidity, and suitability for applications requiring large radial and axial loads.
- Material: Chrome steel GCr15
- Bearing size: Inner diameter 0-200mm, outer diameter 0-400mm
- Cage material: Brass, steel, nylon, etc.
Four row tapered roller bearings are typically used in large machinery equipment such as metallurgy, mining, hoisting equipment, rolling mills, etc. They can stably and reliably support heavy loads and high-speed rotation applications, providing important power transmission and support in the industrial sector.

What is rolling bearings?
Rolling bearings employ a cylindrical roller design, which, compared to ball bearings, allows for the distribution of loads over a larger surface area. They are often more suitable for heavy-load applications.
What are the advantages of cylindrical roller bearings?
Cylindrical roller bearings offer outstanding performance, reliability, and longer lifespan. Theis bearing is tailored to meet the rigorous demands of heavy-duty applications, ensuring efficient machine operation and reducing downtime.
What are rolling bearings and why are they important?
Rolling bearings are mechanical components designed to reduce friction between moving parts and facilitate smooth motion in machinery. Unlike sliding bearings, rolling bearings use cylindrical, needle, or tapered rollers to carry and distribute loads. This rolling action minimizes friction, heat, and wear, making rolling bearings crucial for efficient operation across various industrial applications.
