Static Load (Cor) 51.0kN

Load Capacity (kN) 140kN

Load Capacity (kg) 14271kg

💡What This Means

Dynamic Load (140kN): Maximum force while rotating. Exceeding this causes rapid wear and failure within hours.

Static Load (51.0kN): 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.

FREQUENTLY ASKED QUESTIONS

Expert guidance for 62317 bearing applications

Bearing Selection & Replacement ▼

What makes 62317 bearing suitable for wide-bodied applications?

62317 features 60mm width (vs 12mm standard) providing enhanced load distribution and stability for demanding applications.

Why This Matters

Wide-bodied design reduces stress concentration, extends bearing life, and improves overall system reliability.

How To Handle It

Verify housing dimensions accommodate 60mm width and ensure proper alignment during installation.

Wide-bodied bearings are ideal for applications with high radial loads or where space allows for increased width.

Can 62317 replace standard 85mm bore bearings?

Yes, 62317 can replace standard 85mm bore bearings when enhanced load capacity and stability are required.

Why This Matters

Provides upgrade path for applications experiencing premature bearing failures or requiring higher load ratings.

How To Handle It

Check housing width compatibility (60mm vs 12mm standard) and verify load requirements match 14280.0kg (140kN) rating.

Always verify dimensional compatibility before replacement, especially width requirements.

What are the key advantages of 62317 over standard 85mm bearings?

62317 offers 60mm width, 14280.0kg (140kN) dynamic load capacity, and enhanced stability compared to standard 85mm bearings.

Why This Matters

Wide-bodied design provides superior load distribution, reduced stress, and extended service life.

Installation & Maintenance ▼

What are the proper installation procedures for 62317 bearing?

Use proper tools, maintain cleanliness, apply appropriate force, and ensure correct alignment for 62317 installation.

Why This Matters

Proper installation prevents damage, ensures optimal performance, and maximizes bearing service life.

How To Handle It

Clean shaft and housing, use bearing puller/installer, apply force to inner ring only, and verify smooth rotation.

Never apply force to outer ring during installation as it can damage bearing components.

How often should 62317 bearing be lubricated?

Lubrication frequency depends on operating conditions, speed, and load, typically every 6-12 months for normal applications.

Why This Matters

Proper lubrication reduces friction, prevents wear, and extends bearing service life significantly.

How To Handle It

Use high-quality grease suitable for bearing application, apply appropriate quantity, and monitor lubrication condition regularly.

Over-lubrication can cause overheating, while under-lubrication leads to premature failure.

Keep failed bearings for analysis to identify root causes and prevent future failures.

How to diagnose 62317 bearing problems?

Monitor vibration, temperature, noise levels, and visual inspection to diagnose 62317 bearing problems.

Why This Matters

Early detection allows for planned maintenance and prevents catastrophic failures.

How To Handle It

Use vibration analysis tools, infrared thermography, and regular visual inspections.

Establish baseline measurements when bearing is new to detect changes over time.

What are signs of 62317 bearing wear?

Signs include increased vibration, temperature rise, noise changes, and visual wear patterns on raceways and balls.

Why This Matters

Early detection of wear allows for planned replacement and prevents unexpected failures.
