Introduction to Bearing Numbering Systems

In the world of bearings, each manufacturer has its own unique numbering system to identify and categorize their products. These numbering systems are designed to convey essential information about the bearing’s type, size, and specific features. Understanding the meaning behind these bearing numbers is crucial for ensuring proper selection, installation, and maintenance of bearings in various applications. In this article, we will explore the bearing number meanings used by three renowned manufacturers: THK, IKO, and HIWIN.

THK Bearing Number Meaning

THK is a leading Japanese manufacturer of linear motion guides, ball screws, and industrial bearings. Their bearing numbering system follows a specific pattern that provides insights into the bearing’s characteristics.

THK’s bearing numbers typically consist of four to six alphanumeric characters, with each component carrying a distinct meaning:

  1. Bearing Type: The first character or two characters represent the bearing type, such as “B” for ball bearings or “RB” for roller bearings.
  2. Bearing Series: The second character or set of characters indicates the bearing series, often related to the bearing’s internal design or intended application.
  3. Bore Diameter: The next set of numbers represents the bore diameter of the bearing, typically measured in millimeters.
  4. Additional Features or Variants: Additional characters or numbers may be included to denote specific features, materials, or variants of the bearing.

For example, a bearing number “RB20030” from THK Cross roller bearing, Inner diameter 200mm, height 30mm.

IKO Bearing Number Meaning

IKO is a renowned Japanese manufacturer of bearings, linear motion products, and positioning systems. Their bearing numbering system follows a similar pattern to THK but may include additional characters for specific variants.

IKO’s bearing numbers typically consist of five to seven alphanumeric characters:

  1. Bearing Type: The first character or two characters represent the bearing type, such as “N” for needle roller bearings or “CR” for cross-roller bearings.
  2. Bearing Series: The second character or set of characters indicates the bearing series, often related to the bearing’s internal design or intended application.
  3. Bore Diameter: The next set of numbers represents the bore diameter of the bearing, typically measured in millimeters.
  4. Additional Features or Variants: Additional characters or numbers may be included to denote specific features, materials, or variants of the bearing, such as sealing options or special clearances.

For example, a bearing number “CRBF5515AT” from IKO cross roller bearings, Inner diameter 55mm, height 15mm.

HIWIN Bearing Number Meaning

HIWIN is a leading Taiwanese manufacturer of linear motion guides, ballscrews, and industrial bearings. Their bearing numbering system follows a similar pattern to THK and IKO but may include additional characters to denote specific features.

HIWIN’s bearing numbers typically consist of six to eight alphanumeric characters:

  1. Bearing Type: The first character or two characters represent the bearing type, such as “LM” for linear motion bearings or “RG” for cross-roller ring bearings.
  2. Bearing Series: The second character or set of characters indicates the bearing series, often related to the bearing’s internal design or intended application.
  3. Bore Diameter or Width: The next set of numbers represents either the bore diameter for rotary bearings or the width for linear bearings, typically measured in millimeters.
  4. Additional Features or Variants: Additional characters or numbers may be included to denote specific features, materials, or variants of the bearing, such as sealing options, preload levels, or special coatings.

For example, a bearing number “CRBD08022A” from HIWIN bearing, Inner diameter 80mm, height 22mm.

Importance of Understanding Bearing Number Meanings

Understanding the meaning behind bearing numbers is crucial for several reasons:

  1. Proper Selection: Accurate interpretation of bearing numbers ensures that you select the right bearing for your specific application, taking into account factors such as load capacity, speed rating, and environmental conditions.
  2. Maintenance and Replacement: Correct identification of bearing numbers facilitates proper maintenance and replacement procedures, ensuring compatibility and preventing potential failures.
  3. Technical Documentation: Bearing number meanings are often referenced in technical manuals, catalogs, and engineering drawings, making it essential to understand their significance for effective communication and collaboration within the industry.
  4. Inventory Management: Proper understanding of bearing number meanings aids in efficient inventory management, allowing for accurate tracking and ordering of replacement bearings as needed.

By familiarizing yourself with the bearing number meanings used by manufacturers like THK, IKO, and HIWIN, you can make informed decisions, streamline processes, and ensure the optimal performance and longevity of your bearing applications.
