Compact Dust Protection for Precision Servo Systems

The DMHUI BF6610F VBY Oil Seal (24×37×5mm) is designed for compact servo motor assemblies where space is limited and cleanliness is critical. Featuring a VBY dust-lip structure, it helps reduce the entry of external particles while maintaining stable sealing performance.

Its low-profile 5mm width makes it ideal for tightly integrated systems, ensuring efficient operation without adding unnecessary space or friction.

FAQ

Q: Why is this seal only 5mm wide? Is that a standard size?
A: 5mm is an unusually thin profile for an oil seal, but it is a specific requirement for certain FANUC servo motor housings with shallow cavities. Standard seals are typically 7mm or thicker. The BF6610F is engineered precisely for these space-constrained applications. Always verify your cavity depth — a 5mm seal cannot be replaced with a thicker seal.

Q: What is the difference between VBY and standard TCY seals?
A: VBY typically emphasizes dust exclusion with a more aggressive dust lip geometry. Standard TCY has a balanced primary and secondary lip. The VBY design is often chosen for applications where contamination is the primary concern, while the ultra-thin 5mm profile of the BF6610F is a specific housing requirement.

Q: Can I use a 7mm wide seal if I cannot find a 5mm replacement?
A: No. A 7mm seal is 2mm thicker than the 5mm cavity depth. Attempting to force a thicker seal will damage the housing, prevent proper seating, and likely cause immediate sealing failure or motor damage. Always use the exact width specified.

Q: How do I install this ultra-thin seal correctly?
A: Extreme care is required due to the thin profile. 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 exactly matches the 37mm outer diameter. Apply even, gentle pressure to the outer metal case only — never strike the rubber lip. The VBY dust lip side must face outward. The thin casing is more prone to distortion than thicker seals.

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 aggressive synthetic oils without confirming compatibility.

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 5mm width is critical — do not substitute with thicker seals. Due to the ultra-thin profile, careful installation is essential to prevent casing distortion. For best results, use a proper installation tool matched to the 37mm outer diameter.
