Our customer compared our usual supplies to Chinese No.2 largest factory for large size bearings.
Quality can often be seen by eyes, please focus on surface roughness, chamfer, roller treatment, and to think the price of the ugly looking is much higher than the better quality stuff.
You may see from the picture, 22218 on the right from Findbearing, seems more shining. The reflection of light shows different roughness, focus on the raceway and rollers. Although spherical roller bearings usually do not require vibration test, it is without think that the bearing with good roughness has better performance on noise.
