Single Row Deep Groove Ball Bearings – Miniature

Welcome to www.bearings.co.th, your trusted source for high-performance industrial components. In the realm of compact and high-precision machinery, Single Row Deep Groove Ball Bearings – Miniature play an indispensable role. These meticulously engineered bearings are specifically designed for applications where space is at a premium but reliable rotational motion is paramount. Unlike their larger counterparts, miniature deep groove ball bearings offer exceptional performance in constrained environments, making them a cornerstone of modern miniaturized technology. Their simple design, consisting of an inner ring, an outer ring, a set of balls, and a cage, ensures efficient operation and minimal friction, even at high speeds.

 

What are Single Row Deep Groove Ball Bearings – Miniature?

Single Row Deep Groove Ball Bearings – Miniature are a specific class of rolling-element bearings characterized by their exceptionally small dimensions. They feature a single row of balls running in a deep raceway groove on both the inner and outer rings. This deep groove design allows them to accommodate both radial and axial loads, albeit primarily designed for radial forces. Their miniature size, often with bore diameters less than 10mm, makes them ideal for integrating into devices where larger bearings would be impractical. These bearings are manufactured with high precision to ensure smooth operation, low noise, and extended service life in demanding miniature applications.

 

Applications for Single Row Deep Groove Ball Bearings – Miniature

The versatility and compact nature of Single Row Deep Groove Ball Bearings – Miniature make them essential across a vast array of cutting-edge applications. Their ability to handle high speeds and precision in limited spaces makes them critical components in:

  • Medical Devices: Surgical instruments, dental drills, infusion pumps, laboratory equipment.
  • Robotics: Small robotic arms, actuators, and drones requiring precise movement.
  • Electronics & Optics: Cameras, optical encoders, small motors, disk drives, printers, scanners.
  • Aerospace: Miniaturized sensors, gyroscopes, and control mechanisms in compact aircraft systems.
  • Model Making: Remote control vehicles, miniature engines, and hobbyist projects demanding smooth operation.
  • Precision Instruments: Gauges, meters, and measuring devices where accuracy is paramount.
  • Jewelry Making Equipment: Small polishing and drilling tools.

The demand for Single Row Deep Groove Ball Bearings – Miniature continues to grow as technology advances towards smaller, more efficient designs.

 

Types of Single Row Deep Groove Ball Bearings – Miniature

While the core design of Single Row Deep Groove Ball Bearings – Miniature remains consistent, variations exist primarily in their sealing and shielding configurations, and sometimes in their material composition.

  1. Open Type (No Seals or Shields): These bearings have no protective covers, making them suitable for applications where contamination is not an issue or where lubrication can be easily replenished. They offer the lowest friction but are susceptible to ingress of dust and moisture.
  2. Shielded Type (ZZ/2Z): Equipped with non-contact metal shields on both sides. These shields are pressed into the outer ring and create a narrow gap with the inner ring, providing basic protection against larger contaminants while allowing for high-speed operation.
  3. Sealed Type (2RS/2RS1): Featuring contact seals (usually rubber or synthetic material) on both sides. These seals provide superior protection against dust, dirt, and moisture ingress, and also help retain lubricant. However, they introduce slightly more friction compared to open or shielded types.
  4. Flanged Type: These bearings have a flange on the outer ring, allowing for easier mounting and axial location in housing bores.

 

Mechanics of Different Types of Single Row Deep Groove Ball Bearings – Miniature

The fundamental mechanics of all Single Row Deep Groove Ball Bearings – Miniature involve rolling motion to reduce friction between moving parts.

  • Open Type: The balls roll freely in the raceways, with lubricant directly exposed. This configuration offers the lowest rotational resistance, ideal for very high-speed, clean environments.
  • Shielded Type (ZZ/2Z): The metal shields act as a barrier, deflecting most airborne particles. The small gap between the shield and the inner ring allows for minimal contact, preserving low friction characteristics while offering some protection. Lubrication is typically grease-filled at the factory and is designed for the bearing’s lifespan.
  • Sealed Type (2RS/2RS1): The rubber seals physically contact the inner ring, creating a much more effective barrier against contaminants and ensuring lubricant retention. This contact, while providing superior protection and extended service life in dirty environments, results in slightly higher frictional torque compared to shielded or open types. These are pre-lubricated and are considered “lubricated for life.”

 

What Industries Use Single Row Deep Groove Ball Bearings – Miniature?

The demand for miniaturization across industries has cemented the importance of Single Row Deep Groove Ball Bearings – Miniature. Key industries that heavily rely on these precision components include:

  • Medical & Pharmaceutical: For sterile and precise equipment.
  • Aerospace & Defense: In avionics, guided missiles, and satellite components.
  • Robotics & Automation: For precise movement in collaborative robots and automated assembly lines.
  • Consumer Electronics: In high-end cameras, smart devices, and computer peripherals.
  • Automotive (Specialty): In small sensors, electric motors, and advanced driver-assistance systems (ADAS) where compact components are required.
  • Instrumentation: For highly accurate measurement and control devices.
  • 3D Printing: In the motion systems of advanced 3D printers.
