Tapered roller bearings

1. High load-carrying capacity : The rolling elements of the 30204 tapered roller bearing are conical with a large contact area for distributing the load. The contact lines between the tapered rollers and the inner and outer rings converge at the axis of the bearing, forming a good force distribution, enabling it to withstand large radial and unidirectional axial loads simultaneously. 

2.Stability and durability : Multiple rollers of the 30204 tapered roller bearing can contact the raceway at the same time. The multi-point contact characteristic improves the stability of the bearing.

3.Good impact resistance : The 30204 tapered roller bearing has been optimized by QIBR technicians and can withstand inertial forces and frictional forces from different directions. 

Deep Groove Ball Bearings

1. High load-carrying capacity : 1.The raceway of the 6210Z high-precision deep groove ball bearing is deep, which can accommodate more rolling elements and improve the load-carrying capacity.

2.Stability and durability : The structural characteristics of the 6210Z high-precision deep groove ball bearing enable the load to be evenly distributed, reducing local stress concentration. And QIBR bearings adopt high-strength steel and advanced heat treatment processes to ensure the durability of the bearings in harsh environments.

3.Good impact resistance : The raceway of the 6210Z high-precision deep groove ball bearing adopts a deep groove design, increasing the contact area between the raceway and the rolling elements, enabling the load to be evenly distributed, reducing local stress concentration, and improving the impact resistance.

Additional Notes:

The American customer decided to purchase the 30204 tapered roller bearings and 6210Z high-precision deep groove ball bearings from QIBR for the main shaft and auxiliary shaft of the ship propulsion system. QIBR tapered roller bearings and high-precision deep groove ball bearings can adapt to various working environments, including harsh conditions such as high temperature, high humidity, and salt spray, ensuring the reliable operation of the ship under various complex working conditions. Through large-scale production and lean management, QIBR can provide more competitive prices. Compared with other brands, it can reduce the procurement cost and increase the overall profit margin while ensuring durability and stability.
