Frequently Asked Questions About Industrial Bearings
Get expert answers to common questions about industrial bearing selection, maintenance, and sourcing.
How do I choose the right bearing for my application?
Consider these key factors: load type (radial vs axial), load magnitude, operating speed, temperature range, and environmental conditions. Deep groove ball bearings suit high-speed applications, while tapered roller bearings handle combined loads. View our product range or read our complete guide.
What is the difference between sealed and shielded bearings?
Sealed bearings (2RS) have rubber seals on both sides, providing superior contamination protection and retaining lubricant better. Shielded bearings (2Z) have metal shields that are non-contact, suitable for higher speeds but offer less密封 protection.
How often should industrial bearings be lubricated?
lubrication intervals depend on operating conditions. General guidelines: daily visual inspection, weekly temperature checks, monthly lubrication condition assessment, and quarterly complete inspection. Learn more about bearing maintenance.
What bearing materials are available?
Common materials include: Chrome steel (standard), Stainless steel (corrosion-resistant), Ceramic (high-speed applications), and Carbon steel (economical option). We also offer custom materials for special requirements.
Do you offer custom bearing sizes?
Yes, we provide custom sizing services tailored to your specific requirements. Our engineering team can help you select or customize bearings for unique applications. Contact us at [email protected].
What is the typical lead time for orders?
Standard products ship within 3-7 business days. Custom bearings typically require 2-4 weeks for production. We offer expedited services for urgent requirements.
What quality certifications do your bearings have?
Our bearings meet international standards including ISO 9001 quality management certification, ISO 281 bearing life ratings, and original manufacturer certificates with full traceability.
Do you ship internationally?
Yes, we ship to 50+ countries worldwide with professional packaging. We work with trusted logistics partners to ensure safe and efficient global delivery.
