FAQs

1. What is the difference between ball bearings and roller bearings?

Ball bearings use spherical balls as rolling elements, while roller bearings use cylindrical rollers. Roller bearings can handle heavier loads, while ball bearings offer higher speeds and reduced friction.

2. How do I select the right bearing for my application?
Consider factors such as load capacity, speed, precision, and environmental conditions. Consulting with a bearing specialist is recommended for complex applications.

3. How long do bearings typically last?
The lifespan of bearings depends on various factors, including application, maintenance, and environmental conditions. Proper lubrication and regular inspections can extend bearing life.

4. What are the signs of a failing bearing?
Listen for unusual noises, vibrations, or increased friction. Inspect bearings for signs of wear, corrosion, or contamination.

5. Can I repair or replace bearings myself?
Basic bearing maintenance tasks can often be performed by individuals with mechanical skills. However, complex repairs or replacements should be entrusted to trained technicians.

6. How can I store bearings properly?

Store bearings in a clean, dry place at a moderate temperature. Protect them from moisture, dust, and extreme temperature fluctuations.
