Xintre Trailer Wheel Bearing Kit L44649/L44610 for 1-1/16" Axles — 2-Set with 12192TB & 15192TB Seals, Cotter Pins

Xintre’s 2-set trailer wheel hub bearings kit supplies inner and outer L44649/L44610 bearings, matching races, two grease seals (12192TB and 15192TB), cotter pins and tang washers for 1-1/16" trailer axles.

This factory-style replacement kit gathers the bearings, races and seals most commonly used on 1-1/16" (1.063" ID) trailer axles rated around 2,000 lb. It’s designed for straightforward hub rebuilds or trailer maintenance intervals, letting you replace worn components in matched pairs to restore quiet, smooth wheel rotation. The package includes two sets so both sides of an axle can be serviced at once.

Will these bearings and races fit my 1-1/16" trailer axle?

If your axle spindle measures 1-1/16" (approximately 1.063" ID for the bearing inner diameter), these L44649 inner and outer bearings and L44610 races are the standard match. Confirm by measuring the bearing inner diameter and the existing race seat before installation.

• Inner and outer bearings: L44649, ID 1.063" x OD 1.980"
• Inner and outer races: L44610, ID 1.063" x OD 1.980"
• Designed for common 1-1/16" spindle/taper geometries
• Includes two complete sets to service both hub sides

Which grease seals are included and why two sizes?

The kit contains two grease seals: 12192TB and 15192TB. These seals have slightly different inner diameters (1.250" and 1.500") so the kit covers hubs that use either seal size; verify the seal seat diameter on your hub or existing seal before pressing in the new seal.

• 12192TB grease seal: 1.250" ID x 1.979" OD x 0.250" width
• 15192TB grease seal: 1.500" ID x 1.983" OD x 0.250" width
• Both seals keep grease in and contaminants out of the hub bearings
• Choose the seal by hub bore measurement for a correct press fit

What hardware is included for reassembly and safety?

Beyond bearings, races and seals, the kit provides cotter pins and tang washers needed to secure the spindle nut and maintain correct preload during reassembly. These small parts help lock adjustments in place and reduce the risk of the wheel coming loose when installed correctly.

• 2 cotter pins for spindle nut retention
• 2 tang washers to hold the nut in adjusted position
• Complete pairs so both sides of an axle can be secured
• Use correct torque and bearing preload procedures during install

How should I maintain these components after installation?

Proper lubrication and periodic inspection extend service life: pack bearings thoroughly with high-temperature wheel bearing grease, install the correct seal, and check for play or noise after initial miles and during routine inspections. Replace seals whenever bearings are serviced to prevent contamination.

• Pack bearings with automotive wheel bearing grease before installation
• Inspect hub for scoring, corrosion, or heat discoloration during service
• Check wheel end preload and re-torque axles per manufacturer specs
• Replace seals any time bearings or races are changed

Who is this for: This Xintre kit is aimed at trailer owners, DIY mechanics and small fleet operators who need an economical, matched replacement set for 1-1/16" spindles. It suits routine hub rebuilds on utility trailers, boat trailers, campers and light-duty equipment trailers where restoring quiet rotation and reliable lubrication retention are the goal. Confirm measurements and follow safe installation procedures or consult a trailer service shop if unsure.
