Metric double row tapered roller bearings

Single-row metric tapered roller bearings solve several key problems in various fields, which are mainly reflected in the following aspects:

1. Single-row metric tapered roller bearings have high load-bearing capacity

The contact angle between the inner ring, outer ring and roller of a single-row metric tapered roller bearing is usually a cone, which can bear large radial and axial loads at the same time. Due to its rolling contact method, the load distribution of this type of bearing is relatively uniform and the load-bearing capacity is relatively high.

2. Single-row metric tapered roller bearings have good wear resistance

Single-row metric tapered roller bearings are particularly suitable for bearing radial loads and axial loads acting simultaneously. The contact angle of the bearing (usually between 15° and 30°) determines its load-bearing capacity for axial loads, so it is often selected in applications with high loads and high reliability requirements.

3. Single-row metric tapered roller bearings have adjustable clearance

During the installation process of single-row metric tapered roller bearings, the radial clearance between the inner and outer rings can be adjusted according to actual needs. This adjustability enables the bearings to adapt to different working conditions and thus obtain the best operating performance.

4. Good adaptability

Due to the geometric characteristics between the inner and outer rings and rolling elements of the single-row metric tapered roller bearings, it can adapt to a certain axial displacement. During the process of operation, the bearings can effectively withstand the eccentricity or axial displacement of the shaft and have good adaptability.

Performance improvement and solutions for single-row metric tapered roller bearings

1. Improve high-speed adaptability

Improve the structure of the bearing, reduce the friction between the inner and outer rings, and reduce the temperature rise during the process of operation, thereby improving the high-speed operation capability of the bearing.

2. Corrosion resistance

By selecting corrosion-resistant materials, or surface coatings or plating, the working ability of the bearing in harsh environments such as moisture, salt spray, acid and alkali can be improved, and the service life can be extended.

3. Improve manufacturing accuracy

Adopt advanced foreign processing equipment and processes, such as precision grinding, super-finishing grinding, etc., to improve the geometric accuracy of the inner and outer rings and rollers, reduce processing errors, and thus improve the rotation accuracy and roughness of the bearing.

4. Improve material properties

The carburizing process is used to harden the surface of the material, while its core (heart) still retains a low hardness and good toughness. This structure enables the bearing to maintain sufficient toughness when subjected to large loads, avoiding cracking or fragmentation due to impact or excessive fatigue.
