Self-aligning Ball Bearing

Double sealed deep groove ball bearing

Description：

Double-sealed bearings are commonly used in applications where environmental conditions may be harsh or where there is a need to prevent lubricant leakage or contamination. They are found in various industries including automotive, industrial machinery, agriculture, and more. The sealing arrangement helps to prolong the life of the bearing by maintaining proper lubrication and preventing the ingress of harmful contaminants, thereby reducing friction and wear. This type of bearing is often preferred in applications where maintenance is limited or difficult to perform regularly.
