DMHUI VC Single Lip Springless Oil Seal – 5H-15210 (33x46.3x4.1/3mm)

Designed specifically for Eaton hydraulic motor repair kits, this VC-type oil seal serves as a direct replacement for OEM part 5H-15210, commonly found in Eaton motor repair kit 61329-000. Featuring a single-lip, springless design with a rubber-covered outer diameter, it provides reliable grease retention and light contamination exclusion in compact motor assemblies. The unique dual-width profile (4.1/3mm) accommodates specific housing geometries found in Eaton motors.

Key Points

VC Single-Lip Springless Design: The VC configuration features a single sealing lip without a garter spring. The sealing force is generated by the inherent elasticity of the rubber compound itself, making it ideal for grease retention and light-duty sealing applications.

Rubber-Covered Outer Diameter: The VC seal incorporates a full rubber coating over the metal casing. This design improves static sealing against the housing bore, accommodating minor bore imperfections and reducing the risk of leakage around the seal's outer circumference.

Dual-Width Profile (4.1/3mm): The unique width specification (4.1mm or 3mm) reflects a stepped or tapered profile designed for specific Eaton motor housings. This geometry allows the seal to fit precisely into cavities where standard uniform-width seals cannot be used.

Low-Friction Operation: Without a spring-loaded lip, the VC seal generates lower friction and heat compared to spring-energized seals. This makes it suitable for applications where minimizing heat generation is important.

Durable NBR Construction: The nitrile rubber compound offers good resistance to greases, lubricating oils, and moderate temperatures, with an operating range of -40°C to +100°C. 

Direct Eaton Repair Kit Replacement: Manufactured to match 5H-15210 OEM specifications, this seal is a direct-fit component for Eaton motor repair kit 61329-000.

VC is a specialized oil seal designation. Unlike common TC or SC seals that use a garter spring to maintain lip contact pressure, the VC type is springless. The sealing lip relies entirely on the rubber's elastic memory to maintain contact with the shaft. This design offers several advantages: lower friction, reduced heat generation, and simpler installation. However, it is typically suited for lower-pressure applications such as grease retention or viscous fluid sealing.

The VC seal also features a rubber-covered outer diameter (OD). This means the metal casing is fully encapsulated in rubber, which improves sealing against the housing bore and accommodates minor bore surface imperfections — a common consideration in hydraulic motor repair scenarios.

The 5H-15210 seal has a distinctive dual-width specification: 4.1/3mm. This indicates either a stepped profile where the seal is 4.1mm at one point and 3mm at another, or a tapered design that fits into a specific housing geometry. In Eaton motor repair kit 61329-000, this seal serves as a grease retention element or an ancillary seal against light to medium dust and dirt. Its compact 33mm shaft and 46.3mm bore dimensions are tailored to the motor's shaft and housing interface.

Ideal For Use In
Eaton hydraulic motors
Eaton Motor Repair Kit 61329-000
Hydraulic drive systems
Industrial machinery maintenance

Installation Tips
Verify shaft and housing dimensions before installation.
Clean the shaft and bore thoroughly.
Lightly lubricate the sealing lip prior to assembly.
Use an appropriate installation tool to press the seal evenly.
Avoid damaging the sealing lip during installation.

FAQ

Q: What does VC mean on this oil seal?
A: VC indicates a single-lip, springless seal design with a rubber-covered outer diameter. Unlike TC or SC seals that use a garter spring, the VC seal relies on the rubber's elasticity for sealing force, resulting in lower friction and heat generation.

Q: Is this seal compatible with Eaton motor repair kit 61329-000?
A: Yes. This 5H-15210 seal is specifically designed for use in Eaton motor repair kit 61329-000. It is a direct replacement component for that repair kit.

Q: Can I use this seal for high-pressure applications?
A: The VC seal is springless and primarily designed for grease retention and light-duty sealing. For high-pressure hydraulic applications, a spring-loaded seal (such as TC or SC types) would be more suitable. This seal is intended for ancillary or low-pressure sealing roles within the motor assembly.

Q: What is the temperature range for this seal?
A: The NBR material offers an operating temperature range of -40°C to +100°C (-40°F to 212°F).

Q: Is this an original Eaton part?
A: No, this is a high-quality aftermarket replacement manufactured to match OEM 5H-15210 specifications for fit, material, and performance.

Note: This product is an aftermarket replacement component. Always verify the OEM part number and dimensions from your original seal or Eaton motor repair kit documentation prior to purchase. The dual-width profile (4.1/3mm) is a specific design feature — confirm your housing geometry matches this specification. Proper installation is essential for optimal sealing performance.
