Comprehensive Guide to the Versatile 13x5x4 Bearing Dimensions Ball Bearing

Introduction

The 13x5x4 bearing dimensions ball bearing, often referred to as the 608 bearing, is a widely used and versatile component in various applications, ranging from everyday machinery to high-precision instruments. Its compact size, load-bearing capacity, and low friction make it an indispensable part of numerous industries.

Technical Specifications

The 13x5x4 bearing dimensions are as follows:

• Inner Diameter (ID): 13 mm
• Outer Diameter (OD): 5 mm
• Width (W): 4 mm

Load Capacity

The load capacity of a 13x5x4 bearing is crucial in determining its suitability for specific applications. The load capacity can vary depending on the bearing type, material, and manufacturing process.

According to the Anti-Friction Bearing Manufacturers Association (AFBMA), the basic static load rating for a standard 13x5x4 bearing is approximately 725 lbf (3200 N). This rating represents the maximum load that can be applied to the bearing without causing permanent deformation.

Friction and Speed Capabilities

The 13x5x4 bearing is known for its low friction characteristics. The coefficient of friction for this type of bearing is typically around 0.005, making it suitable for high-speed applications.

The maximum permissible speed for a 13x5x4 bearing is dependent on the bearing type, lubrication, and operating conditions. Generally, the permissible speed ranges from 10,000 to 15,000 RPM for sealed bearings and up to 25,000 RPM for open bearings.

Types of 13x5x4 Bearings

The 13x5x4 bearing is available in different types, each designed for specific applications:

Single Row Deep Groove Ball Bearing (608): This is the most common type of 13x5x4 bearing. It offers a simple and cost-effective solution for general-purpose applications.

Double Row Deep Groove Ball Bearing (608-ZZ): This bearing features two rows of balls, providing increased load capacity and rigidity.

Radial Contact Ball Bearing (608-RS): This bearing is designed to accommodate radial loads and is commonly used in high-speed applications.

Angular Contact Ball Bearing (608-C): This bearing is suitable for applications involving combined radial and axial loads.

Applications

The 13x5x4 bearing dimensions ball bearing finds applications in a wide range of industries, including:

• Automotive (engines, transmissions, wheel hubs)
• Aerospace (instruments, actuators, control systems)
• Medical equipment (surgical tools, imaging systems)
• Industrial machinery (pumps, fans, conveyors)
• Appliances (washing machines, refrigerators)

Benefits of Using 13x5x4 Bearings
