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 sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed  makes radial and axial loads in both directions, so it requires little maintenance.

Knowledge and introduction of bearings                                                                                                         

The KOYO 625 deep groove ball bearing is a miniature bearing known for its precision and reliability.

KOYO 625 Deep Groove Ball Bearing:

• Type and Design: The KOYO 625 is a miniature deep groove ball bearing, which is part of the metric series with an outer diameter less than 9mm.

  These bearings are designed to handle high radial loads and light axial loads in both directions. They are optimized for high running accuracy, quiet operation, and very high speeds.

• Materials: KOYO 625 bearings are typically made from materials such as carbon steel, bearing steel, stainless steel, plastic, and ceramic.

  These materials ensure the bearing's durability and performance in various applications.

• Sealing: The KOYO 625 bearing can feature a non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z), which allows for higher speeds than bearings with rubber seals.

  This sealing provides better protection against contaminants while maintaining high-speed capabilities.

• Applications: These bearings are ideal for a wide variety of light-duty instrument and precision applications.

  They are commonly used in industrial equipment, small rotary motors, and other high-speed, low-noise fields

  such as office equipment, micro motors, instruments, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepping motors,

  video recorder drums, toy models, computer cooling fans, bill counting machines, fax machines, and more.

• Series and Variants: The KOYO 625 bearing belongs to the 623 series, which includes other similar miniature deep groove ball bearings like 623, 624, 625, 626, 627, 628, and 629.

  These bearings are part of the broader deep groove ball bearing family, which includes various series like 604, 61800, 61900, and 6200, among others.

• Performance: KOYO 625 bearings are known for their good fixed bearing properties, but they can also be used as floating bearings in both directions.

  This versatility makes them suitable for a wide range of applications where both precision and adaptability are required.

The KOYO 625 deep groove ball bearing is a high-quality, reliable choice for applications where small size, high speed, and low noise are paramount.

Its design and construction make it a popular choice in many industries and applications around the world.
