Frequently Asked Questions
Q: What is the MEA 821 o ring used for?
A: The MEA 821 is an o ring seal component for electric lift truck assemblies. It is used in pump seals, cylinder connections, hose interfaces, and other sealed bearing or hydraulic applications where dynamic or static sealing is required.
Q: What equipment types use the MEA 821 o ring?
A: The MEA 821 is designed for electric lift trucks and compatible material handling equipment. It functions as a replacement seal in hydraulic systems, bearing assemblies, and connection points that require consistent sealing performance.
Q: How often should the MEA 821 o ring be replaced?
A: The MEA 821 o ring should be replaced when you observe oil leaks, reduced seal integrity, or during scheduled bearing or pump maintenance. Typical service intervals are 2 to 3 years depending on operating conditions and fluid exposure.
Q: What materials is the MEA 821 o ring made from?
A: The MEA 821 is manufactured from standard elastomer compounds formulated for hydraulic fluid compatibility and temperature stability in electric lift truck service. The material resists compression set and maintains seal performance across typical operating ranges.
Q: Is the MEA 821 a static or dynamic seal?
A: The MEA 821 o ring is suitable for both static and dynamic sealing applications in electric lift truck assemblies. Static applications include fixed connections, while dynamic applications include rotating shafts and moving cylinder rods.
