Understanding SKF Bearing Nomenclature: A Comprehensive Guide

When it comes to industrial applications, precision and reliability are paramount, and that’s where SKF bearings shine. As one of the world's leading manufacturers of bearings, SKF offers a wide range of high-quality products that meet the needs of various industries. However, understanding the nomenclature of SKF bearings can be a complex task for those unfamiliar with the coding system. This guide will simplify the process and help you navigate through the intricate details of SKF bearing nomenclature, ensuring you make the right choice for your application.

At Smart Parts Exports, we are proud to be the largest wholesaler and exporter of SKF genuine bearings from India, serving customers worldwide, including Russia. In this blog, we will break down SKF-bearing nomenclature, explain the key codes and terms, and offer practical insights into selecting the best bearings for your needs.

Why Understanding SKF Bearing Nomenclature Matters

SKF bearing nomenclature is a standardized naming convention that helps you identify the type, size, and design of a bearing quickly. Whether you're looking at an SKF 6207 bearing, SKF 6307 N bearing, or SKF angular contact ball bearing, understanding the nomenclature is essential to ensure you are selecting the correct product for your machinery or equipment.

This nomenclature can also be useful when searching through the SKF bearing catalogue online, cross-referencing bearings with other brands, or verifying product specifications.

Breaking Down SKF Bearing Nomenclature

Let’s look at how SKF bearing nomenclature is structured and what each component means. A typical bearing code, such as SKF 6207, includes various details about the bearing’s type, size, and internal structure.

1. Bearing Series (First Digit or Two Digits)

The first digit in the bearing code refers to the type of bearing. For example:

• 6 indicates a single-row deep groove ball bearing, such as in the SKF 6207 bearing.

• 7 refers to angular contact ball bearings, such as the SKF angular contact bearing.

Other common series include cylindrical roller bearings and spherical roller bearings.

2. Bearing Size (Third and Fourth Digits)

The next two digits provide the bearing’s internal bore diameter in millimeters. In the case of an SKF 6207 bearing, the "07" indicates that the inner diameter is 35mm. The size chart follows standard conventions, such as:

• 00 = 10mm

• 01 = 12mm

• 02 = 15mm

• 03 = 17mm

If you're unsure about the size of the bearing, refer to the SKF bearing size chart for precise measurements.

3. Additional Letters or Numbers (Suffixes)

Suffixes in the bearing code can provide further details about the bearing's design, such as:

• N for a snap ring groove, as seen in the SKF 6307 N bearing.

• Z or ZZ for metal shields on one or both sides.

• RS or 2RS for rubber seals on one or both sides.

By understanding these suffixes, you can easily determine whether a bearing has additional features like seals, shields, or a snap ring.

Different Types of SKF Bearings

SKF offers a variety of bearing types, each suited for different industrial applications. Below are some of the most commonly used types and their unique features.

1. SKF Angular Contact Ball Bearings

Designed to handle both radial and axial loads, SKF angular contact ball bearings are commonly used in applications that require high precision and speed. These bearings are typically used in automotive, aerospace, and machinery industries where high load capacities are needed.

2. SKF Cross Roller Bearings

SKF cross roller bearings are used in applications where high rotational accuracy is required. They are often used in robotics, medical equipment, and machine tools due to their ability to handle both radial and axial loads in all directions.

3. SKF Precision Bearings

For industries requiring ultra-precise tolerances, SKF precision bearings offer unmatched performance. These bearings are often used in high-speed machinery and precision engineering applications.

4. SKF Sealed Bearings

SKF offers a wide range of sealed bearings to prevent contaminants such as dust and moisture from entering the bearing. SKF bearing seals can extend the life of the bearing, especially in harsh environments, ensuring better performance and reduced maintenance costs.

Using SKF Bearing Tools for Selection

SKF provides several online tools to help you select the right bearing for your application. Two of the most useful tools include:

1. SKF Bearing Select: This tool allows you to input your application's requirements and find the best bearing options. Whether you need to find bearings with specific load capacities or sizes, SKF bearing selection can make the process simpler.

2. SKF Bearing Search: This online tool enables you to quickly find the correct bearing by searching for its part number or specifications. It’s a useful tool for cross-referencing and comparing products.

Maintenance and Proper Care of SKF Bearings

Once you’ve selected the correct SKF bearings for your application, it’s crucial to maintain them properly to maximize their lifespan and performance. Below are a few maintenance tips for common SKF bearings.

1. Lubrication

Proper lubrication is essential to ensure the smooth operation of bearings. SKF bearings require specific types of lubrication based on their application and environment. Always refer to the SKF bearing specification to determine the correct lubrication type and schedule.

2. Sealing Solutions

Using the right SKF bearing seals can prevent contaminants from entering the bearing and causing premature failure. SKF offers various sealing solutions tailored for different environments, whether it's extreme heat, moisture, or dust.

3. Installation and Alignment

Improper installation can significantly reduce the lifespan of bearings. Ensure that the bearing is installed correctly, and all alignment issues are addressed before operation.
