Trailer Axles & Axle Parts

Find trailer axles and replacement axle parts for maintaining or repairing trailer running gear. Trailer axles vary by capacity, length, hub face measurement, spring centre measurement, spindle configuration, brake compatibility, and suspension design.

When replacing a complete axle, carefully compare the specifications of the original axle rather than selecting a replacement based only on trailer size or weight.

Trailer Hubs & Hub Assemblies

Shop trailer hubs and hub assemblies for compatible axles and spindles. Products may include idler hubs, replacement hub assemblies, pre-greased hubs, hub kits, and related mounting components.

Correct hub fitment can depend on the inner and outer bearing numbers, spindle dimensions, wheel bolt pattern, wheel stud size, axle capacity, and hub configuration.

Trailer Wheel Bearings & Races

Find trailer wheel bearings, bearing races, bearing kits, and replacement components for routine maintenance and hub repair. Properly maintained bearings are an important part of keeping trailer wheels rotating smoothly and reliably.

Bearing numbers are often one of the most useful references when identifying replacements. Whenever possible, compare the numbers marked on the existing inner and outer bearings and races with the replacement product specifications.

Trailer Grease Seals, Dust Caps & Hub Parts

Shop trailer grease seals, dust caps, grease caps, spindle hardware, washers, nuts, retainers, and related hub components. These smaller parts play an important role in protecting and securing the hub and bearing assembly.

Grease seals can vary by inner and outer diameter even when used with similar-looking hubs, so verify the seal dimensions or original part number before ordering.

Trailer Spindles & Axle Components

Find trailer spindle components and axle-related replacement parts for compatible trailer running gear. Spindle configuration determines which bearings, seals, hubs, and related components can be used, making accurate identification important when rebuilding an existing assembly.

Trailer Suspension & Running Gear Maintenance

Axles, hubs, bearings, wheels, brakes, and suspension components work together as part of the trailer's running gear. Inspect related components when servicing an axle or hub, particularly when there is evidence of unusual tire wear, excessive bearing play, overheating, damaged seals, or other mechanical issues.

Finding the Correct Trailer Axle, Hub or Bearing

Before ordering, verify relevant specifications such as the axle capacity, hub face and spring centre measurements, spindle dimensions, inner and outer bearing numbers, race numbers, grease seal dimensions, wheel bolt pattern, stud size, and manufacturer part number.

Trailer running-gear components that appear similar are not necessarily interchangeable. When identifying bearings, hubs, and seals, use existing part numbers and precise measurements whenever possible.
