Both are 35x90x8mm TCY seals.\u003cbr\u003eA: While both share the same dimensions and TCY double-lip design, the OEM part numbers differ. BH6657E and BE6657F typically correspond to different FANUC motor series or may have subtle differences in lip compound or spring specification. Always use the exact part number from your original seal or equipment manual. A BH6657E is not guaranteed to function identically to a BE6657F.\u003c\/p\u003e\n\u003cp\u003eQ: Is this seal compatible with my FANUC servo motor?\u003cbr\u003eA: Yes, the BH6657E seal is designed as a direct replacement for specific FANUC servo motor systems that call for a 35x90x8mm TCY-type seal with this exact OEM number. Verify your original seal part number or check your motor documentation before ordering.\u003c\/p\u003e\n\u003cp\u003eQ: How do I install this seal correctly?\u003cbr\u003eA: Clean the shaft and housing bore thoroughly. Apply a thin film of clean grease to the seal lip. Use a flat installation tool or a socket that matches the outer diameter (90mm). Press the seal squarely into the housing bore, applying even pressure to the outer metal case only. The double-lip side (with the dust lip visible) must face outward toward the external environment.\u003c\/p\u003e\n\u003cp\u003eQ: What fluids is this seal compatible with?\u003cbr\u003eA: The NBR material is compatible with most mineral-based greases and lubricating oils used in FANUC servo motors and robotic gearboxes. Avoid use with brake fluids, phosphate esters, or high-temperature synthetic oils unless compatibility is confirmed.\u003c\/p\u003e\n\u003cp\u003eQ: Do you offer other seals for FANUC servo motors and robotic arms?\u003cbr\u003eA: Yes. We stock a wide range of seals for FANUC systems, including BH6656E, BE6656F, BE6657F, BC3554E, BE3554E, AH0616E, and others.

Always verify the OEM part number and dimensions from your original seal or equipment manual prior to purchase. While dimensionally similar to BE6657F, BH6657E is a distinct part number — confirm compatibility before ordering.
