Rubber Seale/Greased Radial Deep Groove Ball Bearings 6203

Introduction

The rubber seale/greased radial deep groove ball bearing is a type of rolling element bearing used in various applications, including industrial machinery, automotive components, and consumer products. The 6203 designation refers to the bearing's specific dimensions and characteristics.

History/Background

The development of ball bearings dates back to the late 19th century. In 1898, German engineer Friedrich von Kessler patented the first ball bearing design, which used a needle bearing with a ball bearing as the rolling element. Over time, various manufacturers and engineers refined the design, leading to the creation of different bearing types and designs.

Key Concepts

The rubber seale/greased radial deep groove ball bearing operates on the principle of rotational motion, where one or more balls are embedded in a cylindrical shell. The bearings use a combination of grease and seals to reduce friction and prevent contaminants from entering the bearing.

Cross-Sectional View

A cross-sectional view of a rubber seale/greased radial deep groove ball bearing shows the following components:

• Ball bearing (deep groove design)
• Outer ring
• Inner ring
• Seals (rubber seals)
• Grease compartment

Circumferential View

A circumferential view of the same bearing shows the following components:

• Bearing surface (bearing grooves)
• Rolling elements (balls)
• Oil channels for lubrication

Technical Details

The 6203 bearing has the following specifications:*

• Outer diameter: 17mm (0.67 in)
• Inner diameter: 14mm (0.55 in)
• Height: 5.5mm (0.22 in)
• Circumferential clearance: H7
• Tolerance class: 6

The bearing also comes with a grease cartridge and two seals, which provide lubrication and protection against contaminants.

Applications/Uses

The rubber seale/greased radial deep groove ball bearing is used in various applications, including:

• Machinery for the automotive industry (e.g., engines, gearboxes)
• Rolling element bearings for industrial machinery
• Consumer products (e.g., toys, appliances)

Impact/Significance

The rubber seale/greased radial deep groove ball bearing plays a crucial role in the smooth operation of various machinery and systems. By reducing friction and preventing contamination, these bearings contribute to increased efficiency, reliability, and lifespan.
