FAQ

Q: Is this seal suitable for my FANUC servo motor?
A: Yes, this BC3554E seal is designed as a direct replacement for specific FANUC servo motor models that call for a 24x78x7mm SC-type seal. Verify your original seal part number or measure your shaft, bore, and cavity width to confirm compatibility.

Q: What is the difference between SC and TC seals?
A: SC has one sealing lip (for fluid retention). TC has two lips: a primary fluid retention lip and a secondary dust lip to block contaminants. SC is typically used in cleaner environments or where space does not allow a double-lip design.

Q: Can I use this seal if my motor operates in a dusty environment?
A: The SC seal lacks a dedicated dust lip. If your servo motor operates around dust, dirt, or debris, consider adding external protection (such as a cover or wiper) or consult with us about double-lip alternatives that fit the same dimensions.

Q: Is this an original FANUC part?
A: No, this is a high-quality aftermarket replacement manufactured by DMHUI to match OEM BC3554E specifications for fit and performance.

Q: Do you offer other seals for FANUC servo motors?
A: Yes. We stock various seals for FANUC motors, including BH6656E, BE6656F, BE6657F, and others. Search our store by OEM part number or contact us with your requirements.

Note: This product is an aftermarket replacement component. Verify the OEM part number and dimensions from your original seal or equipment manual before ordering. Proper installation is essential for optimal sealing performance. For dusty environments, consider additional contamination control measures.
