625 Bearing
The 625 bearing is a common deep groove ball bearing. The following introduces it from dimensions, performance characteristics, application scenarios, and other aspects:

Basic Information

• Model: 625
  • "6" indicates the bearing type is a deep groove ball bearing.
  • "2" represents the width series as 2.
  • "5" denotes the inner diameter is 5mm.
• Brands:  625 bearings from different brands may vary in quality, performance, and price.

Dimensions

• Inner diameter: 5mm
• Outer diameter: 16mm
• Thickness: 5mm

Performance Characteristics

1. Low Friction Resistance:
   The structure of deep groove ball bearings results in a low friction coefficient between rolling elements and raceways, reducing energy loss and improving mechanical efficiency.
2. High Rotational Speed:
   Capable of stable operation at high speeds, suitable for equipment requiring high-speed rotation.
3. Moderate Load Capacity:
   Can bear certain radial loads and bidirectional axial loads, but not pure axial loads. For example, the basic dynamic load rating of  625 is 1.14kN, and the basic static load rating is 0.38kN.
4. Simple Structure:
   Composed of basic components such as inner rings, outer rings, rolling elements, and cages, making it relatively easy to manufacture and install.
5. Easy Maintenance:
   Requires minimal frequent maintenance and has a long service life, ensuring stable operation for extended periods under normal conditions.

Application Scenarios

1. Model Making:
   Used in aircraft models, car models, etc. High precision and stability requirements of 625 bearings ensure smooth rotation and movement of model components.
2. Micro Robots:
   Applied to the joints of micro robots to enable precise movements. Their small size and high precision adapt to the compact structural designs of micro robots.
3. Toys:
   Used in toy cars, toy planes, yo-yos, etc., to make rotating parts more flexible and enhance playability and performance.
4. Electronic Devices:
   Installed in small motors, fans, hard disk drives, etc., to ensure stable operation of rotating parts while reducing noise and vibration.
5. Instruments and Meters:
   Used in precision measurement and control devices (e.g., microscopes, telescopes, measuring instruments), where 625 bearings provide high-precision rotational support to ensure accuracy and stability.

Installation and Removal

Installation

• Ensure precise fitting between the bearing, shaft, and housing to avoid looseness or excessive tightness.
• Common methods include:
  • Press-Fit Method: Use specialized tools to evenly press the bearing onto the shaft or into the housing.
  • Thermal Installation Method: Heat the bearing to expand it, then slide it onto the shaft. It will tightly fit the shaft after cooling.

Removal

• Use appropriate removal tools (e.g., pullers) to avoid damaging the bearing or shaft.
• If the bearing is tightly installed, heat the housing or cool the shaft to increase the fitting clearance for easier removal.

      Characteristics and performance features of deep groove ball bearings
          1. Structural features: Each ring of deep groove ball bearings has a continuous groove type raceway with a cross-section of
           approximately one-third of the circumference of the ball. This structure enables deep groove ball bearings to withstand radial
           loads as well as a certain amount of axial loads.
         2. Load bearing capacity: Deep groove ball bearings have excellent load bearing capacity and can withstand large radial and
           axial loads. This is due to the geometric shape of its inner and outer rings and the use of high strength
        3. Friction characteristics: The friction coefficient of deep groove ball bearings is very small, and the maximum speed is very
          high.This makes it suitable for high-speed mechanical equipment.
        4. Wear resistance performance: The inner and outer ring surfaces of deep groove ball bearings undergo high-precision heat
          treatment,resulting in high hardness and strong wear resistance, which can effectively reduce mechanical failures and repair
          costs causedby wear.
        5. Maintenance convenience: Deep groove ball bearings have a simple structure, are easy to use, and do not require          frequent
          maintenance.This greatly improves its reliability and economy in practical applications.
      6. Application scope: Deep groove ball bearings have a particularly wide range of applications. It can be used in industries
         suchas precisioninstruments, low-noise motors, automobiles, motorcycles, and general machinery.
      7. Diversity of types: There are various types of deep groove ball bearings, including deep groove ball bearings with dust  covers,
         deep groove ball bearings with rubber seals, and deep groove ball bearings with stop grooves. These different types can meet
         different workingconditions and performance requirements.
