Dynamic Load (Cr) 26.8kN
Static Load (Cor) 9.95kN
Load Capacity (kN) 26.8kN
Load Capacity (kg) 2731kg

💡What This Means

Dynamic Load (26.8kN): Maximum force while rotating. Exceeding this causes rapid wear and failure within hours.
Static Load (9.95kN): Maximum force when stationary. Use 80% for safety.
Calculate Your Load: Measure shaft forces, belt tensions, or gear loads. Include shock/vibration factors.
Failure Warning: Overloading causes bearing raceways to crack and balls to flatten permanently.

Why This Matters
Proper bore fit prevents slippage, reduces vibration, and ensures maximum load transfer efficiency.
How To Handle It
Measure shaft diameter precisely and select h6 tolerance for standard applications or consult for special requirements.
Use proper installation tools to avoid damaging bearing during press-fit installation.

Can 62211 replace other 55mm bore bearings?

Yes, 62211 is ISO 15:2011 compliant and directly interchangeable with other standard 55x100x25mm bearings.
Why This Matters
Standard dimensions ensure seamless replacement without equipment modification or downtime.
How To Handle It
Verify load and speed requirements match 62211 specifications (2733.6kg (26.8kN) dynamic, 6,400 RPM).
Check seal type compatibility - open, shielded, or sealed versions available.

What's the difference between 62211 and 6211 bearings?

62211 has 25mm width vs 21mm in 6211, providing higher load capacity (2733.6kg (26.8kN) vs 43.2kN) and better stability.
Why This Matters
Increased width distributes loads more effectively and provides better resistance to misalignment.
How To Handle It
Choose 62211 for higher load applications or when additional stability is required.
62211 series offers better performance in applications with axial loads or vibration.
Installation & Maintenance ▼

What's the proper installation procedure for 62211 bearing?

Use proper bearing installation tools, apply force to outer ring only, and ensure shaft and housing are clean and properly sized.
Why This Matters
Correct installation prevents bearing damage, ensures optimal performance, and maximizes service life.
How To Handle It
Heat housing to 80-100°C for interference fits, use installation sleeves, and avoid hammering directly on bearing.
Professional installation can extend bearing life by 50% compared to improper methods.

How often should 62211 bearing be lubricated?

Open bearings require regular lubrication every 3-6 months; sealed bearings are lubricated for life and don't require maintenance.
Why This Matters
Proper lubrication prevents wear, reduces friction, and maintains optimal operating temperature.
How To Handle It
Use high-quality grease suitable for bearing speed and temperature conditions.
Monitor bearing temperature - increase of 15°C above ambient indicates lubrication issues.

How To Handle It
Check lubrication levels, verify load ratings, and inspect for misalignment or contamination.
Temperature increase of 15°C above ambient requires immediate attention.

What causes excessive noise in 62211 bearing?

Noise typically results from contamination, insufficient lubrication, or bearing damage from improper handling.
Why This Matters
Unusual noise indicates potential failure and should be addressed immediately.
How To Handle It
Inspect for contamination, check lubrication, and examine bearing for visible damage.
Use vibration analysis tools for early detection of bearing issues.

How do I identify if 62211 bearing needs replacement?

Signs include excessive play, rough rotation, unusual noise, high temperature, or visible damage to raceways or balls.
