❓ Frequently Asked Questions (FAQs)
Q1: What’s the benefit of the double lip design in this rotary shaft oil seal?
A: The secondary (dust) lip adds protection by excluding contaminants while the primary lip retains lubricant, extending the life of both the seal and surrounding components.
Q2: Is this seal suitable for continuous rotation at high speed?
A: Yes. The nitrile rubber construction combined with the steel-reinforced case and garter spring provides excellent sealing under dynamic, high-speed rotary motion—ideal for both industrial and automotive applications.
