Double Row Tapered Roller Bearings
Double row tapered roller bearings are an important type of bearing characterized by a arrangement of tapered rollers between the inner and outer rings, capable of simultaneously bearing radial and axial loads in both directions. These bearings are featured by stable structure, high load capacity, and suitability for high-speed rotation.
- Material: Chrome steel GCr15
- Bearing size: Inner diameter 0-200mm, outer diameter 0-400mm
- Cage material: Brass, steel, nylon, etc.

Double row tapered roller bearings are typically used in automotive transmission systems, steering systems of engineering machinery (such as cranes, excavators, and forklifts), transmission systems or rotating systems, main bearings of wind power systems, gearboxes, etc., providing reliable support and protection for various heavy loads, high speeds, and complex working conditions.
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.
