⚡Load Ratings

Dynamic Load (Cr) 57.8kN

Static Load (Cor) 50.0kN

Load Capacity (kN) 57.8kN

Load Capacity (kg) 5891kg

💡What This Means

Dynamic Load (57.8kN): Maximum force while rotating. Exceeding this causes rapid wear and failure within hours.

Static Load (50.0kN): 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 6019 bearing applications

Bearing Selection & Replacement ▼

What clearance should I choose for the 6019 bearing?

C0 (normal clearance) is standard for most 6019 bearing applications, providing optimal performance under normal operating conditions.

Why This Matters

Proper clearance selection affects bearing performance, noise levels, and service life. Wrong clearance can cause premature failure or excessive wear.

How To Handle It

Use C0 clearance for standard applications. Consider C3 clearance for high-temperature applications or when thermal expansion is a concern.

For high-speed applications, C3 clearance may be beneficial as it accommodates thermal expansion and reduces friction.

Installation & Maintenance ▼

What is the expected service life of the 6019 bearing?

Under proper operating conditions, the 6019 bearing can provide 50,000+ hours of service life with appropriate maintenance and lubrication.

Why This Matters

Understanding expected service life helps with maintenance planning, inventory management, and total cost of ownership calculations.

How To Handle It

Monitor bearing condition regularly, maintain proper lubrication, and replace bearings before they reach end of life to prevent equipment damage.

Service life can vary significantly based on load, speed, temperature, and maintenance practices. Regular condition monitoring is essential.

Troubleshooting & Problem Solving ▼

How do I identify bearing failure in the 6019?

Common signs of 6019 bearing failure include increased noise, vibration, heat, and reduced performance or complete seizure.

Why This Matters

Early detection of bearing failure prevents catastrophic equipment damage and reduces downtime and repair costs.

How To Handle It

Implement regular condition monitoring, use vibration analysis, and establish maintenance schedules based on operating conditions.

Keep spare bearings in stock and establish emergency replacement procedures to minimize downtime when failures occur.

Cost & Performance Optimization ▼

How can I optimize the performance of my 6019 bearing?

Optimize 6019 bearing performance through proper installation, regular maintenance, appropriate lubrication, and monitoring operating conditions.

Why This Matters

Optimized performance extends bearing life, reduces maintenance costs, and improves overall equipment reliability and efficiency.

How To Handle It

Follow manufacturer guidelines, implement preventive maintenance, use quality lubricants, and monitor bearing condition regularly.

Keep detailed maintenance records and use condition monitoring to identify optimization opportunities and prevent problems before they occur.
