The 602 bearing belongs to the micro deep groove ball bearing category. The following introduction will cover its dimensional parameters, performance characteristics, application areas, and key points for installation and maintenance:
Basic Information
- Model: The model of this bearing is 602. Here, "6" indicates the deep groove ball bearing type, "0" represents the width series as 0, and "2" is the inner diameter size code.
Dimensional Parameters
- Inner Diameter: 2 mm
- Outer Diameter: 7 mm
- Thickness: 2.8 mm
- Overall Dimensions:
- B1: 3.5 mm
- rmin (Minimum Chamfer Radius): 0.15 mm
- r1 (Minimum Chamfer): 0.15 mm
- Mounting Dimensions:
- da (Minimum): 3.2 mm
- db (Maximum): 3.8 mm
- Da (Maximum): 5.8 mm
- ra (Maximum): 0.15 mm
- b (Maximum): 0.15 mm
Performance Characteristics
- Low Friction Resistance: The structure of deep groove ball bearings ensures that the friction between rolling elements and raceways is primarily rolling friction, with a low friction coefficient. This reduces energy loss and improves equipment operational efficiency.
- High Rotational Speed: Capable of stable operation at high speeds, suitable for components requiring high-speed rotation, such as motors and small fans.
- Moderate Load Capacity: Can withstand certain radial loads and small axial loads, meeting the application needs of various light to medium loads.
- Long Service Life: Under normal working conditions, with proper installation and maintenance, the 602 bearing has a long service life, ensuring stable equipment operation.
Application Areas
- Industrial Equipment: Widely used in sewing machines, vertical lathes, energy-saving environmental protection equipment, gear reducers, casting and heat treatment equipment, process pumps, etc., supporting the normal operation of key rotating components in these devices.
- Electronic Equipment: Such as micro motors and power tools, providing support for motor shafts to ensure efficient motor operation.
- Medical Devices: Including diagnostic equipment, traction and correction equipment, monitoring equipment, and treatment equipment. The high precision and low noise characteristics of 602 bearings facilitate precise operation and stable performance of medical devices.
- Household Appliances: For example, electric fans, air conditioners, washing machines, etc., used to support motor shafts or other rotating components and ensure normal appliance operation.
- Sports Equipment: Such as roller skates and yo-yos, providing a smooth rotation experience to meet the performance requirements of sports equipment.
Installation and Maintenance
- Installation: Ensure the installation surface is clean and flat to prevent impurities from entering the bearing. Use appropriate tools for installation to avoid damaging the bearing, and pay attention to installation accuracy to ensure the bearing fits the shaft and housing bore as required.
- Lubrication: Selecting the right lubricant is crucial for bearing performance and service life. Generally, for 602 bearings, suitable grease or lubricating oil can be chosen based on working temperature, rotational speed, and other conditions. Regularly check the quantity and quality of the lubricant and replenish or replace it in a timely manner.
- Sealing: To prevent dust, moisture, and other impurities from entering the bearing, effective sealing measures are required. Appropriate sealing methods, such as seals and dust covers, can be selected according to the actual application scenario.
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.
