U-Cup
Frequently Asked Questions
Q: What equipment type does the BG 036-118 U-Cup fit?
A: The BG 036-118 is a U-cup seal designed for electric lift truck hydraulic systems. Confirm your equipment type and model compatibility with the Blue Giant documentation before ordering.
Q: What is the functional purpose of a U-cup seal in lift trucks?
A: The U-cup seal design creates dual sealing lips that prevent bidirectional hydraulic fluid leakage in pump cylinders and rod applications. This geometry is standard for dynamic sealing in pressurized hydraulic circuits.
Q: How does the BG 036-118 differ from standard O-ring seals?
A: U-cup seals like the BG 036-118 provide superior dynamic sealing performance compared to simple O-rings. The dual-lip design reduces friction and leakage under cycling pressure conditions found in electric lift truck applications.
Q: What material composition supports electric lift truck duty cycles?
A: OEM U-cup seals for electric lift trucks are typically nitrile rubber, engineered to withstand repeated pressure cycling, temperature variation from electric motor operation, and exposure to mineral hydraulic fluids.
Q: What operational conditions affect BG 036-118 seal lifespan?
A: Seal lifespan is affected by cycle frequency (lift/lower operations), ambient temperature range, hydraulic fluid cleanliness, system pressure consistency, and proper seal seating depth during service. Dirty fluid or excessive heat accelerates wear.
