FAQ

Q: Is this an original FANUC part?
A: No, this is a high-quality aftermarket replacement manufactured by DMHUI to match OEM AH0616E specifications for fit, material, and performance.

Q: Can I use a single-lip SC seal instead of this HTC double-lip seal?
A: While a single-lip seal of the same dimensions might physically fit, it would lack the dust lip, leaving your servo motor vulnerable to contamination. If your original seal is AH0616E (HTC), replace it with the same type to maintain proper contamination protection.

Q: How do I install this small 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 a socket that matches the outer diameter (37mm). 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. Due to the small size, avoid using excessive force.

Q: What fluids is this seal compatible with?
A: 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 without confirming compatibility.

Q: Do you offer other small-size seals for FANUC servo motors?
A: Yes. We stock a range of seals for FANUC systems in various sizes, including AH0616E, BH6656E, BE3554E, 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. The 7mm width is critical — measure your housing cavity depth carefully. Proper installation is essential for optimal sealing performance in compact servo motor applications.
