Product Description

The 6218-2Z bearing is a double-shielded deep groove ball bearing designed for reliable performance in moderate-load industrial applications. With a bore diameter of 90 mm, outer diameter of 160 mm, and width of 30 mm, this 6218-2Z ball bearing features dual metal shields (2Z) to protect against contaminants while retaining lubrication. Its chrome steel construction supports dynamic and static load capacities of 103 kN and 72 kN respectively, operating smoothly at speeds up to 4,800 rpm under grease lubrication. The 2Z shielded ball bearing excels in machinery like motors, pumps, and conveyor systems, offering low noise, reduced friction, and extended service life. It operates optimally within -30°C to +120°C and tolerates brief exposure to higher temperatures. Though unsuitable for extreme high-speed or submerged environments, its balance of durability and cost-effectiveness makes it ideal for general manufacturing and automotive applications.
