• Outer Diameter: 47 mm
• Width: 14 mm
• Max. Radial Load Capacity: 2,250 N
• Max. Axial Load Capacity: 1,090 N
• Speed Limit: 6,000 RPM

Applications of 6203 Bearings

6203 bearings are ubiquitous in numerous industries, including:

• Automotive: - Gearboxes - Transmission systems - Driveline components
• Industrial: - Turbines - Pumps - Conveyors - Textile machinery
• Medical: - MRI machines - Laboratory equipment - Surgical tools

Maintenance and Lubrication

Proper maintenance is crucial for extending the lifespan of 6203 bearings. Regular lubrication is essential to reduce friction and prevent premature wear. The recommended lubricant type and frequency may vary depending on the application and operating conditions.

Lubrication Guidelines

• Use a high-quality, lithium-based grease.
• Apply a thin layer of lubricant to the bearing surfaces.
• Replenish lubricant as advised by the manufacturer or as per the operating conditions.

Troubleshooting Common Issues

Identifying and resolving common issues with 6203 bearings is essential for maintaining system efficiency. Here are some common problems and their potential solutions:

Noise

• Cause: Lack of lubrication, improper installation, or bearing damage.
• Solution: Lubricate the bearing, check for proper installation, or replace the damaged bearing.

Vibration

• Cause: Unbalanced load, misalignment, or shaft defects.
• Solution: Balance the load, align the components, or inspect the shaft for any damage.

Failure

• Cause: Excessive load, contamination, or improper maintenance.
• Solution: Examine the bearing for damage, identify the root cause of failure, and implement preventive measures.

Step-by-Step Approach to Installing 6203 Bearings

1. Prepare the shaft and housing: Clean and inspect the shaft and housing surfaces.
2. Apply lubricant: Spread a thin layer of lubricant on the shaft and bearing surfaces.
3. Position the bearing: Carefully align and place the bearing onto the shaft.
4. Drive the bearing: Use a suitable tool to gently drive the bearing into the housing.
5. Apply the remaining lubrication: Apply a second layer of lubricant to the exposed bearing surfaces.
