Product Description

The W 619/3-2Z bearing is a compact 2Z shielded ball bearing designed for precision applications requiring minimal friction and reliable operation. As a 619/3 deep groove bearing, it features dual metal shields (2Z) to protect against contaminants, enhancing durability in harsh environments. With an inner diameter of 3 mm, outer diameter of 8 mm, and width of 4 mm, it supports radial loads up to 0.25 kN and operates efficiently at speeds up to 45,000 rpm. Suitable for temperatures from -30°C to +110°C, it is widely used in small motors, medical devices, and precision instruments. Key advantages include low noise, extended service life, and maintenance-free operation, though its axial load capacity is limited compared to angular contact bearings. This shielded ball bearing excels in compact designs where space and contamination resistance are critical.
