Spherical Roller Bearing

1. Self-aligning ability: 22208 spherical roller bearings can automatically adjust the relative position of the inner and outer rings, compensate for the eccentricity and installation errors of the shaft, and ensure the stable operation of the mine hoist under high load conditions.

2. High load-bearing capacity: With two rows of rollers, it can simultaneously withstand large radial loads and bidirectional axial loads, which is suitable for mine hoists to work under high radial load environments.

Tapered roller bearing

1. Withstand complex loads: 32228 tapered roller bearings adopt a tapered raceway design and can withstand radial and axial loads at the same time, making them suitable for use in mine hoists under complex load conditions.

2. High precision and stability: 32228 tapered roller bearings are heat-treated and precision-machined to maintain good geometry under high load and high-speed operation, and have good stability at high speed, ensuring the smooth operation of the hoist.

Additional Notes:

The Portuguese customer decided to purchase QIBR's 22208 spherical roller bearings and 32228 tapered roller bearings to improve the safety and stability of its mine hoists. 22208 spherical roller bearings and 32228 tapered roller bearings have excellent load-bearing capacity and can withstand heavy loads and impact loads. It is particularly suitable for the high-intensity working environment of mine hoists to ensure stable operation. When there is a certain angle deviation between the bearing seat and the shaft of the 22208 spherical roller bearing, it can effectively compensate for the centering error generated during operation and improve the tolerance of the system. The 32228 tapered roller bearing has low friction characteristics, which can effectively reduce energy loss and improve the operating efficiency of mine hoists.
