| Deep groove ball bearing with seals or shields | |||||||||
Deep groove ball bearing with seals or shields Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea ling prolongs bearing service life Simple, versatile and robust design Low friction and high-speed capability Accommodate radial and axial loads in both directions Require little maintenance |  | ||||||||
Knowledge and introduction of bearings | |||||||||
The W 638/3-2Z deep groove ball bearing is a compact, precision-engineered bearing designed for applications requiring space efficiency and protection from contaminants. Made from high-grade stainless steel, this bearing provides excellent durability and resistance to corrosion, making it suitable for challenging environments and demanding applications. The dual metal shields (2Z) keep out dust and debris, ensuring that internal lubricant is retained, which minimizes maintenance and extends the lifespan of the bearing. Designed for low friction, the W 638/3-2Z offers smooth, reliable performance even at high rotational speeds, making it ideal for applications in small motors, precision instruments, robotics, and other compact devices that require stable, consistent performance. Its optimized design combines durability with efficient operation, ensuring a balance of strength and performance in miniature systems. Key Features and Benefits:
