Otoolling Trailer Hub Grease Seals 8-Pack Double-Lip ID 2.250" x OD 3.376" — Carbon Steel, Fits 5200–7000 lb Axles

These Otoolling seals replace common part numbers such as 01003600, 10-36, 22333TB, GS-2250DL, 452920, 482920 and fit D42 spindles and typical 5200–7000 lb axle setups. Each pack contains eight identical double-lip seals made from durable carbon steel and engineered to deliver a snug fit and extended service life under highway and storage conditions. The double-lip profile helps retain lubricants while keeping dirt, water and road debris away from bearings and spindle surfaces.

How do these seals prevent axle leaks?

The double-lip configuration creates two interference points that limit lubricant escape and slow contaminant ingress. One lip contacts the rotating surface to retain grease, while the second provides a backup barrier against external debris and moisture. A precise ID/OD sizing ensures a close fit to common spindle and hub bores, improving sealing performance.

• Two sealing lips for primary and secondary retention
• Accurate ID 2.250" and OD 3.376" dimensions for consistent fit
• Carbon steel construction resists deformation and abrasion

Will these seals fit my trailer axle or hub model?

These Otoolling seals are intended for most 5200, 6000 and 7000 lb trailer axles and D42 spindle configurations. They are listed as compatible replacements for multiple OEM numbers, so they suit many RVs, utility trailers, boat trailers and enclosed trailers. Always measure your existing seal bore and spindle before installation to confirm match.

• Replaces 01003600, 10-36, 22333TB and GS-2250DL
• Compatible with 452920, 482920, AD3135E1 and AD3135EO numbers
• Designed for 5200–7000 lb axle weight classes and D42 spindles

What materials and durability features do these seals offer?

Otoolling uses carbon steel for dimensional stability and wear resistance in the sealing housing, combined with sealing lips engineered to handle oil and grease exposure. The construction tolerates typical road grime, oil splashes and seasonal weather without rapid breakdown. That durability reduces the frequency of rebuilds and helps protect bearings from premature failure.

• Carbon steel body for strength and corrosion resistance
• Oil- and corrosion-resistant sealing surfaces for longevity
• Designed for repeated installation and routine maintenance cycles

How should I install and maintain these seals for best results?

Installation requires clean surfaces, light lubrication on the sealing lip, and even seating to avoid distortion. Use a proper seal driver sized to the OD and tap evenly around the perimeter until the seal is flush with the hub bore. Inspect seals periodically for leaks and replace them when you see grease loss, contamination ingress or lip damage.

• Seat with a driver tool to avoid bending the lip
• Apply thin film of grease on lip and bore prior to installation
• Check regularly during routine axle or wheel maintenance

Who is this for: Owners and technicians who service trailers, RVs and utility equipment with 5200–7000 lb axles and D42 spindles. This 8-pack suits fleet operators, weekend trailers and DIY mechanics who want a reliable supply of replacement seals that match common OEM numbers. If you need a robust, double-lip seal to protect bearings and retain lubricants on standard trailer hubs, these Otoolling seals offer a practical, cost-effective option.
