Product Description
Deep groove ball bearings are the most commonly used rolling bearings, belong to non-separated bearings, which are simple structure, easy to use and low price. Basic deep groove ball bearings are composed of inner ring, outer ring, steel balls, and cage. The cages are mostly stamped steel corrugated cages or engineering plastic solid cages, while large bearings use metal solid cages.
There are 2 types of deep groove ball bearings, single-row and double-row. The structure is also divided into 2 types: open type and closed type. The open type means that the bearing is not sealed; the closed type means that it has seal. There are 2 types of sealing structure: dust-proof seal and oil-proof seal.
Double row deep groove ball bearings are similar in design to single row deep groove bearings. It consists of outer ring, inner ring, cage and double row steel balls. Double row deep groove ball bearings mainly bear radial loads and can also bear bidirectional axial loads.
Double row deep groove ball bearings are suitable for bearing arrangements where the load capacity of a single row deep groove ball bearing is insufficient. For the double row deep groove ball bearing with the same outer diameter and inner diameter as the deep groove ball bearing, its width is larger and the load capacity is also much higher than that of the single row deep groove ball bearing of the 62 and 63 series.
Double row deep groove ball bearings can only tolerate an angular misalignment of 2 minutes of arc. Larger angular misalignment can overload the balls and raceways, shorten bearing life, and cause increased noise.
Main applications:
Automobiles, agricultural machinery, machine tools, motors, water pumps, textile machinery and other fields.

How do Temperature and Environmental Conditions Affect the Performance of Ball Bearings?
Temperature and environmental conditions have a significant impact on the performance and longevity of ball bearings. The operating environment can influence factors such as lubrication effectiveness, material properties, and overall bearing behavior. Here’s how temperature and environmental conditions affect ball bearing performance:
- Lubrication:
Temperature variations can affect the viscosity and flow characteristics of lubricants. Extreme temperatures can cause lubricants to become too thin or too thick, leading to inadequate lubrication and increased friction. In high-temperature environments, lubricants can degrade, reducing their effectiveness.
- Material Properties:
Temperature changes can alter the material properties of the bearing components. High temperatures can lead to thermal expansion, affecting bearing clearances and potentially causing interference between components. Extreme cold temperatures can make materials more brittle and prone to fracture.
- Clearance Changes:
Temperature fluctuations can cause changes in the internal clearance of ball bearings. For instance, at high temperatures, materials expand, leading to increased clearance. This can affect bearing performance, load distribution, and overall stability.
- Corrosion and Contamination:
Harsh environmental conditions, such as exposure to moisture, chemicals, or abrasive particles, can lead to corrosion and contamination of bearing components. Corrosion weakens the material, while contamination accelerates wear and reduces bearing life.
- Thermal Stress:
Rapid temperature changes can result in thermal stress within the bearing components. Differential expansion and contraction between the inner and outer rings can lead to stress and distortion, affecting precision and bearing integrity.
- Noise and Vibration:
Temperature-related changes in material properties and internal clearances can influence noise and vibration levels. Extreme temperatures can lead to increased noise generation and vibration, affecting the overall operation of machinery.
- Lubricant Degradation:
Environmental factors like humidity, dust, and contaminants can lead to premature lubricant degradation. Oxidation, moisture absorption, and the presence of foreign particles can compromise the lubricant’s performance and contribute to increased friction and wear.
- Seal Effectiveness:
Seals and shields that protect bearings from contaminants can be affected by temperature fluctuations. Extreme temperatures can lead to seal hardening, cracking, or deformation, compromising their effectiveness in preventing contamination.
- Choosing Appropriate Bearings:
When selecting ball bearings for specific applications, engineers must consider the expected temperature and environmental conditions. High-temperature bearings, bearings with specialized coatings, and those with enhanced sealing mechanisms may be necessary to ensure reliable performance.
Overall, understanding the impact of temperature and environmental conditions on ball bearing performance is crucial for proper bearing selection, maintenance, and ensuring optimal operation in diverse industries and applications.
What is a Ball Bearing and How does it Function in Various Applications?
A ball bearing is a type of rolling-element bearing that uses balls to reduce friction between moving parts and support radial and axial loads. It consists of an outer ring, an inner ring, a set of balls, and a cage that separates and maintains a consistent spacing between the balls. Here’s how ball bearings function in various applications:
- Reduction of Friction:
Ball bearings function by replacing sliding friction with rolling friction. The smooth, spherical balls minimize the contact area between the inner and outer rings, resulting in lower friction and reduced heat generation.
- Radial and Axial Load Support:
Ball bearings are designed to support both radial loads (forces perpendicular to the shaft’s axis) and axial loads (forces parallel to the shaft’s axis). The distribution of balls within the bearing ensures load-carrying capacity in multiple directions.
- Smooth Rotational Movement:
Ball bearings facilitate smooth and precise rotational movement. The rolling motion of the balls allows for controlled and continuous rotation with minimal resistance.
- Applications in Machinery:
Ball bearings are used in a wide range of machinery and equipment, including motors, generators, gearboxes, conveyors, and fans. They enable the efficient transfer of motion while reducing wear and energy losses.
- Automotive Industry:
Ball bearings are extensively used in automobiles for various applications, including wheel hubs, transmission systems, steering mechanisms, and engine components. They provide reliability and durability in challenging automotive environments.
- Industrial Machinery:
In industrial settings, ball bearings support rotating shafts and ensure the smooth operation of equipment such as pumps, compressors, and machine tools.
- High-Speed Applications:
Ball bearings are suitable for high-speed applications due to their low friction and ability to accommodate rapid rotation. They are used in applications like electric motors and aerospace components.
- Precision Instruments:
For precision instruments, such as watches, cameras, and medical devices, ball bearings provide accurate rotational movement and contribute to the overall performance of the instrument.
- Variety of Sizes and Types:
Ball bearings come in various sizes, configurations, and materials to suit different applications. Different types include deep groove ball bearings, angular contact ball bearings, thrust ball bearings, and more.
In summary, ball bearings are essential components in a wide range of applications where smooth rotation, load support, and reduced friction are critical. Their versatility, reliability, and efficiency make them indispensable in industries spanning from automotive to industrial machinery to precision instruments.
