• Outer Diameter: 52 mm (2.047 in)
• Width: 15 mm (0.591 in)
• Load Capacity: 10.7 kN (2,381 lbs) radial, 6.5 kN (1,455 lbs) axial
• Speed Limit: 9,500 rpm

Maintenance of 6205 Bearings

Proper maintenance is essential to ensure optimal performance and extend the lifespan of 6205 bearings. Key maintenance strategies include:

• Lubrication: Use high-quality grease or oil designed for bearings. Relubricate at regular intervals (typically every 6-12 months).
• Inspection: Regularly inspect bearings for signs of wear, damage, or contamination.
• Replacement: Replace bearings that show signs of excessive wear or damage to prevent catastrophic failure.

Troubleshooting Common Issues

Common issues associated with 6205 bearings include:

• Noise: Excessive noise can indicate improper lubrication, bearing wear, or misalignment.
• Vibration: Vibration can be caused by unbalance, excessive load, or bearing damage.
• Premature Failure: Early bearing failure can result from contamination, improper mounting, or overloading.

Effective Strategies for Troubleshooting

To effectively troubleshoot 6205 bearing issues:

• Identify the symptoms: Describe the specific noise, vibration, or failure symptoms observed.
• Inspect the bearing: Visually examine the bearing for signs of wear, damage, or contamination.
• Lubricate or clean the bearing: If lubrication or contamination is suspected, apply fresh grease or clean the bearing.
• Check alignment: Verify that the bearing is properly aligned with the shaft and housing.
• Consult the manufacturer: If the issue persists, reach out to the bearing manufacturer for technical assistance.

Step-by-Step Approach to Mounting and Dismounting 6205 Bearings

Mounting:

1. Clean the shaft and housing surfaces.
2. Apply a thin layer of grease or threadlocker to the shaft.
3. Carefully insert the bearing onto the shaft, ensuring it is fully seated.
4. Tighten the retaining collar or cap to secure the bearing.

Dismounting:

1. Loosen the retaining collar or cap.
2. Use a bearing puller to carefully remove the bearing from the shaft.
3. Clean the bearing and inspect for any damage or wear.
