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 |  | ||||||||

The W 639/3-2RS1 deep groove ball bearing is a robust, compact solution designed to perform efficiently in challenging applications. This high-quality bearing, tailored for precision and longevity, offers a dual-seal design that enhances its durability, making it a reliable choice for various demanding environments. Key Specifications:
Product Details: The W 639/3-2RS1 bearing is crafted for high-seal efficiency, utilizing dual-rubber seals on both sides to protect against contaminants like dust, moisture, and other particles. The 2RS1 seal technology ensures reliable performance in harsh environments by keeping the lubricant secure inside the bearing while preventing foreign materials from entering, thus reducing the need for frequent maintenance. The compact dimensions—3 mm inner diameter, 9 mm outer diameter, and 4 mm thickness—make this bearing a smart choice for applications where space is at a premium, such as in medical equipment, robotics, precision instruments, and miniature motors. Its deep groove design enables the bearing to handle both radial and light axial loads effectively, supporting smooth, consistent operation under various loads and speeds. Manufactured from high-grade stainless steel, the W 639/3-2RS1 bearing provides superior resistance to corrosion and wear, making it ideal for long-term, high-performance use. The deep groove structure, coupled with the high-seal design, allows for stable and quiet rotation, enhancing the bearing’s suitability for high-precision applications. This bearing's design also optimizes friction management, enabling smoother, higher-speed operations with minimal energy loss. The W 639/3-2RS1’s well-engineered dual-seal configuration is ideal for applications that demand durability and reliability without frequent lubrication maintenance. Its construction meets the needs of advanced industrial setups by combining compactness, resilience, and functionality in a single bearing. With its high-seal, low-maintenance design, the W 639/3-2RS1 is an ideal choice for professionals seeking a compact yet reliable component for high-precision equipment. Suitable for both new designs and replacements, it is built to support consistent, high-quality performance across a diverse range of industrial applications. | |||||||||
