| 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 639/3-2Z deep groove ball bearing is designed to meet the needs of high-precision applications in compact spaces. This premium-grade bearing features a dual-shield (2Z) construction, providing reliable protection against contaminants while supporting consistent, smooth operation across various applications. Key Specifications:
Product Details: The W 639/3-2Z bearing offers a dual-shield configuration, with metal shields on both sides to protect the bearing interior from dust, debris, and moisture. This design minimizes maintenance needs by securing the lubrication within the bearing, making it a durable solution for applications where space is limited and operational consistency is critical. With its deep groove architecture, this bearing can handle radial and moderate axial loads with ease, offering excellent stability even at higher speeds. The compact size, featuring a 3 mm inner diameter, a 9 mm outer diameter, and a 4 mm width, makes it ideal for tight spaces in precision devices, such as small motors, medical equipment, and other miniature mechanisms. The bearing’s stainless steel composition provides added corrosion resistance, contributing to a longer lifespan and reliable performance in demanding environments. Engineered for smooth, high-speed functionality, the W 639/3-2Z is built to reduce friction and support stable rotations, making it highly suitable for delicate and precision-requiring applications. This W 639/3-2Z bearing is well-suited for engineers and manufacturers who need a high-quality, low-maintenance component that combines durability with compactness. Whether for new designs or as a replacement, this bearing is crafted to provide smooth, efficient operation across a range of challenging industrial settings. | |||||||||
