Enhanced Sealing for Demanding Servo Motor Systems

The DMHUI BH5944E HTCY Oil Seal (35×106×8mm) is engineered for precision servo motor applications where both oil retention and contamination protection are essential. Featuring a double-lip HTCY structure, this seal helps maintain internal lubrication while reducing the entry of dust and external particles.

With an increased 8mm width, it provides improved structural stability, making it suitable for larger servo motor assemblies and high-duty applications.

Key Points

FAQ

Q: What is the difference between HTCY and standard TCY?
A: HTCY indicates a heavy-duty version of the TCY double-lip design. It typically features a reinforced lip profile and a stronger metal casing, providing better resistance to vibration, temperature changes, and moderate contamination. For FANUC servo motors in robotic arms, HTCY is often specified for added durability.

Q: Is this seal compatible with my FANUC servo motor or robotic arm?
A: Yes, the BH5944E seal is designed as a direct replacement for specific FANUC servo motor systems that call for a 35x106x8mm HTCY-type seal. Check your original seal part number or measure your shaft (35mm), housing bore (106mm), and cavity width (8mm) to confirm.

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 a large-diameter socket that contacts the outer metal case evenly. Press the seal squarely into the housing

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 unless compatibility is confirmed.

Q: Do you offer other seals for FANUC servo motors and robotic arms?
A: Yes. We stock a range of seals for FANUC systems, including BC3554E, BE3554E, BC3555E, BH6656E, BE6656F, 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 8mm width is critical — do not substitute with 7mm seals. Proper installation is essential for optimal sealing performance in servo motor and robotic arm applications.
