Frequently Asked Questions
NBR is cost-effective and excellent for general oil and fuel applications, while FKM (Viton) offers superior heat resistance and chemical stability for extreme environments.
Replacement should occur during major engine overhauls or when signs of seepage are detected. We recommend a preventative check every 50,000 miles.
Yes, our marine bearings are manufactured using specialized corrosion-resistant polymers and alloys specifically designed for harsh saline environments.
Absolutely. We offer full OEM customization based on your technical drawings and specific application requirements.
A cassette seal is a pre-assembled unit that protects bearings from contaminants and retains lubricants, ideal for heavy-duty machinery.
Selection depends on the bolt diameter and the fluid type. Consult our technical chart or provide your vehicle/machine model for an exact match.
