Koyo precision design deep groove ball bearing 6313

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 sea

Knowledge and introduction of bearings

The 6313 Deep Groove Ball Bearing is a type of rolling-element bearing commonly used in a variety of mechanical systems, from industrial machinery to household appliances. It is designed to support both radial and axial loads, making it a versatile and reliable choice for many applications.

1. Basic Description

The 6313 bearing is a single-row deep groove ball bearing with the following general specifications:

• Inner diameter: 65 mm

• Outer diameter: 140 mm

• Width: 33 mm

The "6313" part of the designation follows the international standard for deep groove ball bearings, where the first digit (6) signifies a type of bearing, the second digit (3) indicates a series size, and the last two digits (13) represent the specific bearing size.

2. Design and Structure

The 6313 deep groove ball bearing has a simple design consisting of:

• Outer race (also called the outer ring)

• Inner race (inner ring)

• Ball elements (steel balls)

• Cage (ball separator)

The races are typically made of high-carbon chromium steel, which is heat-treated to improve strength and wear resistance. The balls are often made of steel, ceramic, or other durable materials, depending on the bearing's specific application requirements. The cage helps to maintain proper ball spacing, reducing friction and ensuring smooth rotation.

3. Operating Principle

The deep groove ball bearing operates on the principle of rolling motion. The balls roll between the inner and outer races, distributing the applied load evenly. This rolling action significantly reduces friction compared to sliding contact, which in turn minimizes wear and heat generation.

4. Load Capacity

The 6313 deep groove ball bearing can handle both radial loads (loads applied perpendicular to the axis of rotation) and axial loads (loads applied parallel to the axis of rotation). However, like all bearings, there are limitations on the load that can be safely handled without causing premature failure. For typical applications, the bearing can support moderate radial loads and low-to-moderate axial loads. The load capacity is also influenced by factors such as speed, lubrication, and operating conditions.

5. Applications

The 6313 bearing is used in a wide range of industries and applications, including:

• Electric motors: Often found in motors for appliances, automotive, and industrial equipment.

• Pumps and compressors: Used in fluid handling and compression systems.

• Automobiles: Used in various parts of vehicles, such as in wheel hubs, alternators, and steering systems.

• Industrial machinery: For conveyor systems, industrial fans, and machinery with rotating parts.

• Home appliances: Found in washing machines, refrigerators, and air conditioners.

The versatility of the 6313 bearing makes it suitable for environments where moderate speeds, loads, and temperatures are common.

6. Advantages

The 6313 deep groove ball bearing offers several advantages:

• Low friction: The rolling element design reduces friction, leading to greater energy efficiency.

• Durability: It has a relatively long service life if maintained properly, as it is resistant to wear and has low operating temperature rise.

• Versatility: Capable of handling both radial and axial loads, making it suitable for a wide variety of applications.

• Ease of maintenance: The design is straightforward, and it requires minimal maintenance, especially when lubricated correctly.
