FAQ
1. What is the primary purpose of an oil seal?
Oil seals are mechanical components used to seal lubricating oil and isolate parts to prevent leakage in transmission systems.
2. Which materials are best for high-temperature environments?
FFKM and FKM/Viton offer excellent high-temperature resistance, with FFKM capable of withstanding up to 330°C.
3. Can you customize the hardness of the rubber seals?
Yes, most of our materials, such as NBR, EPDM, and FKM, support customizable hardness ranges, typically between 40A and 90A.
4. What are the key parameters to consider for O-rings?
Key parameters include the inner diameter, cross-section diameter (wire diameter), groove size, working pressure, temperature, and movement speed.
5. Are your oil seals suitable for food-grade applications?
Yes, materials like SIL/VMQ and EPDM are commonly used in food-grade applications meeting FDA standards.
