FDXGYH 4 Pcs 1.98-Inch Bearing Covers
Best For: Budget-conscious buyers needing quick replacements for standard 1.98-inch hubs. These rubber caps are designed for rugged weather resistance and provide a simple, cost-effective solution to seal out wind, rain, and dust. They’re suitable for many basic trailer setups where caps simply need to plug the hub opening.
Why chosen: The set includes multiple caps, offering a ready supply for a fleet of small-bore hubs. The rubber construction emphasizes impact resistance and weather sealing, making them a solid general-use option.
Caution: Confirm the inner diameter and height match your hub before ordering to avoid loose or tight fits. Not ideal for highly specialized axles requiring metal dust cups.
iBroPrat 2pcs Trailer Axle Dust Cap Cup
Best For: Heavy-duty trailers using 1.98″ hubs that benefit from extra seals and robust construction. The set includes spare seals, which helps reduce maintenance downtime when seals wear.
Why chosen: The combination of zinc-plated carbon steel and rubber provides resistance to corrosion, while the included extra seals support longer service intervals. The size is clearly specified, aiding accurate compatibility checks.
Caution: Verify axle capacity and compatibility with your Dexter or similar axles to ensure the seals match your system’s requirements.
Bearing Buddy Bra 19B
Best For: Trailer owners using Bearing Buddy systems who want to prevent over-greasing while keeping the hub area neat and clean. The bra is a practical accessory to manage lubricant levels without removing components.
Why chosen: This option addresses a common maintenance concern—overfilling hubs during service. The bra works with Bearing Buddy assemblies to prevent excess grease from escaping during travel.
Caution: The Bra requires proper removal and lubricant level checks to maintain optimal hub greasing. Not a standalone seal; works in conjunction with the Bearing Buddy system.
SUNCARACCL 4 Pack Hub Cap Rubber Plugs
Best For: Trailers needing flexible rubber plugs for 1.98-inch or nearby hub sizes. The plug design helps seal dust intrusion while allowing easy maintenance access when needed.
Why chosen: The 1.48″ diameter size pairs with many standard hubs and provides a practical option for general-purpose dust protection in varied trailer configurations.
Caution: The size is smaller than some 1.98″ hubs; double-check diameter to ensure proper fit with your specific hub model.
GREPSPUD 4pcs 1.98” Hub Caps
Best For: Buyers seeking a value pack with extra rubber seals for ongoing maintenance and replacements on 1.98-inch hubs used in Dexter EZ Lube setups or similar. The included seals act as convenient backups.
Why chosen: This set combines 1.98-inch caps with spare seals, making it a practical choice for users who want a cost-efficient bundle for routine upkeep and quick replacements.
Caution: The kit emphasizes durability and corrosion resistance; assess your hub’s specific needs for chemical exposure and environmental conditions beforehand.
Buying Guide: How to Choose Boat Trailer Bearing Covers
What size do you need? Measure the hub opening to ensure the cap diameter fits snugly. Common sizes include 1.98 inches for smaller trailers and slightly different variants for EZ Lube and standard axles. Choose a cap with a robust rubber compound or a combination of metal and rubber for added durability in salty or wet environments.
What material offers the best balance? Rubber caps are versatile, resistant to water and debris, and easy to install. Some options pair rubber with carbon steel for enhanced rigidity and rust resistance. For long-term exposure to moisture, look for rust-proof coatings or zinc-plated components.
Do you need extra seals or backup parts? Sets that include extra seals or rubber plugs reduce downtime when parts wear or get damaged. If you frequently service your hubs, a bundle with spares is advantageous.
Is it compatible with your axle type? Confirm whether your trailer uses EZ Lube, standard, or Bearing Buddy systems. Some caps are designed specifically for the Bearing Buddy assembly, while others fit generic 1.98″ hubs. Mismatch can lead to poor sealing or loose fits.
How easy is installation and maintenance? Look for simple press-on caps with clean removal without tools. Some products offer easy replacement plugs to maintain lubrication without disassembly, which can save maintenance time on the road.

FAQ
Q: Will these caps fit all 1.98-inch hubs?
A: Most 1.98-inch caps fit standard trailer hubs, but always verify the inner diameter, height, and compatibility with your axle type before purchasing.
Q: Should I choose rubber or metal-backed caps?

Q: Do I need extra seals with these caps?
A: Extra seals help when you perform frequent maintenance or want backup parts. They reduce downtime by providing ready replacements if a seal wears or deteriorates.
Q: How do I install these caps?
A: For most rubber caps, you press them firmly onto the hub opening until seated. Some products include plugs for added grease containment. Follow the product’s installation notes to ensure a proper seal and avoid over- or under-sealing.
Q: Can I mix brands?
A: Mixing brands is generally acceptable if the sizes match. When in doubt, stick to caps designed for your specific hub model to ensure a proper fit and sealing performance.
Q: How often should I inspect bearing covers?
A: Inspect during routine trailer maintenance. Check for cracks, deformation, or looseness after trips through rough terrain or salty environments, and replace as needed to maintain proper bearing protection.
