Their versatility stems from their radial load capacity and ability to withstand moderate axial loads.

Understanding the 6203 Bearing Code

The 6203 bearing code encapsulates critical information about its dimensions and design:

• 6: Series number (indicates a single-row deep-groove ball bearing)
• 2: Inner diameter in mm (15 mm)
• 03: Outer diameter in mm (40 mm)

Specifications and Performance

6203 bearings boast impressive specifications:

• Static Load Capacity: 6.58 kN
• Dynamic Load Capacity: 15.2 kN
• Limiting Speed: 9,500 rpm
• Tolerance Class: P0

Benefits of 6203 Bearings

6203 bearings offer several advantages:

• High load capacity: Supports both radial and axial loads.
• Long service life: Durable design ensures extended operation.
• Low noise operation: Smooth rotation minimizes noise levels.
• Interchangeability: Complies with international standards, ensuring availability.

Common Mistakes to Avoid

When dealing with 6203 bearings, avoid these pitfalls:

• Overloading: Exceeding load capacities can shorten bearing life.
• Improper lubrication: Insufficient or excessive lubrication can cause premature failure.
• Incorrect mounting: Misalignment or improper installation can lead to uneven wear.
• Contamination: Dirt or debris can damage ball tracks and races.

Step-by-Step Installation

Follow these steps for successful installation of 6203 bearings:

1. Clean the bearing: Remove any dirt or grease.
2. Apply lubricant: Use a suitable lubricant for the application.
3. Position the bearing: Carefully insert the bearing into the housing.
4. Tighten the shaft: Gradually tighten the shaft to the recommended torque.
5. Check alignment: Ensure the bearing is correctly aligned with the shaft.
