FAQ

Q: Is this seal an exact match for my FANUC servo motor A06B-0078-B403?
A: Yes. This seal is manufactured to replicate the original BE6656F part, with dimensions 24x66x6.6mm and HTCY double-lip design, making it a direct fit for that specific FANUC servo motor model.

Q: What makes HTCY different from standard oil seals?
A: HTCY seals feature a double lip design, including a dust lip for additional protection.

Q: Can I use this seal on other equipment besides FANUC motors?
A: While designed specifically for the BE6656F application, it can be used in some rotary shaft application requiring a 24x66x6.6mm double-lip seal, provided the environment and fluids are compatible with NBR rubber. Always verify dimensions and working conditions first.

Q: How do I install this seal correctly?
A: Clean the shaft and housing thoroughly. Apply a light coat of clean grease or oil to the seal lip. Press the seal squarely into the housing bore using a flat installation tool, applying even pressure to the outer metal case only. The double-lip side should face outward (toward the external environment) to block dust.

Q: Do you offer other seals for FANUC servo motors?
A: Yes. We carry a range of seals for various FANUC motor models, including the BE6657F and other sizes. Please search our store or contact us with your specific part number.

Note: This product is an aftermarket replacement component. Verify the part number and dimensions from your original seal or equipment manual before ordering. Proper installation is essential for optimal sealing performance.
