Resistant to extreme temperatures 61902 Precision Miniature Ball Bearing

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

Knowledge and introduction of bearings

The 61902 Precision Miniature Ball Bearing is a premium-quality, single-row deep groove ball bearing designed for high-performance, space-constrained applications. With its compact design and exceptional load-bearing capabilities, this bearing delivers reliable, smooth operation under varying speeds and loads. Perfect for industries that require both high precision and durability in a small package, the 61902 is an ideal choice for applications in electronics, motors, robotics, and high-speed machinery.

Key Features:

1. Space-Saving Design:
   The 61902 bearing offers a compact form factor, with an outer diameter of 28 mm, an inner diameter of 15 mm, and a width of just 7 mm. This makes it perfect for use in applications where space is limited, yet high performance is essential.

2. High-Speed Operation:
   Engineered for high rotational speeds, the 61902 bearing ensures smooth and efficient motion even at elevated RPMs. Capable of handling speeds up to 30,000 RPM (depending on lubrication and environmental factors), it is an excellent choice for applications requiring rapid movement or rotation, such as electric motors, fan systems, and small machinery.

3. Enhanced Load Capacity:
   Despite its compact size, the 61902 bearing is designed to carry both radial and axial loads with exceptional efficiency. Its optimized raceway geometry minimizes friction, enabling the bearing to handle heavy loads while maintaining long-lasting performance.

4. Corrosion and Wear Resistance:
   Manufactured from high-quality steel or stainless steel, the 61902 bearing is built to resist corrosion, wear, and environmental challenges. This makes it suitable for use in a wide range of conditions, including environments with exposure to moisture, dust, and temperature fluctuations.

5. Low Friction and Quiet Operation:
   Featuring precision-engineered raceways and balls, the 61902 bearing operates with minimal friction, which helps reduce wear and tear. Its low friction design also results in quieter operation, making it ideal for noise-sensitive applications such as household appliances, medical equipment, and consumer electronics.

6. Long Service Life:
   The 61902 bearing is designed to provide high durability and extended service life, even in demanding applications. Its high load capacity and low-maintenance design help reduce downtime and increase the overall efficiency of the system in which it is installed.
