FAQ

Q: What is the difference between BE3554E (TCY) and BC3554E (SC)?
A: Both share the same dimensions (24x78x7mm). However, BE3554E is a TCY type with two lips (main seal + dust lip). BC3554E is an SC type with one lip (main seal only). For dusty environments or exposed servo motors, the TCY version is strongly recommended.

Q: Is this seal suitable for FANUC robotic arm applications?
A: Yes. The BE3554E seal is specifically designed for certain FANUC servo motor systems used in automated robotic arms. The double-lip design helps protect the motor's internal bearings and grease from fine particulates common in automation cells.

Q: How do I install this seal correctly?
A: Clean the shaft and housing bore thoroughly. Apply a thin film of clean grease to the seal lip. Use a flat installation tool or appropriately sized socket to press the seal squarely into the housing bore, applying even pressure to the outer metal case only. The double-lip side (the side with the secondary lip visible) must face outward toward the external environment.

Q: Is this an original FANUC part?
A: No, this is a high-quality aftermarket replacement manufactured by DMHUI to match OEM BE3554E specifications for fit, material, and performance.

Q: Do you offer other seals for FANUC servo motors and robotic arms?
A: Yes. We stock a wide range of seals for FANUC systems, including BH6656E, BE6656F, BE6657F, BC3554E, and others. Search our store by OEM part number or motor model.

Note: This product is an aftermarket replacement component. Always verify the OEM part number and dimensions from your original seal or equipment manual prior to purchase. Correct installation is essential for optimal sealing performance, especially in robotic and servo applications where precision and contamination control are critical.
