Frequently asked questions
How do I choose between ball bearings and roller bearings?
Ball bearings suit moderate radial and axial loads with high speed. Roller bearings handle higher radial loads and are better for heavy or shock-loaded applications. Check the load spectrum, speed, and housing space before deciding.
What is the role of seals in bearing life?
Seals keep lubricant inside and keep contaminants out. The wrong seal type can cause overheating, dry running, or contamination ingress. Match the seal to the operating temperature and environment.
How often should bearings be lubricated?
Lubrication intervals depend on the bearing type, operating speed, temperature, and lubricant. Grease-filled bearings may need relubrication only after many operating hours. Oil-lubricated systems often need more frequent checks. Follow the bearing manufacturer guidance and monitor for signs of degradation.
What are common bearing failure modes?
Typical failures include spalling from fatigue, brinelling from improper installation, corrosion from moisture, and overheating from insufficient lubrication. Proper analysis distinguishes between design issues and installation errors.
How should I verify bearing quality from a supplier?
Request certificates of conformity, heat treatment records, and dimensional inspection reports. Check for traceability and ask about dimensional tolerance classes. Inspect for surface defects and verify seal integrity on delivery.
What standards should I reference when specifying bearings?
Refer to international standards for bearing dimensions, load ratings, and performance. These standards define terminology and testing methods used across the industry. Always confirm that the supplier follows the relevant standard version.
