Description

 Trailer Axles

Round trailer axle beam measures 60″ from hub-face-to-hub-face and 48″ from spring-center-to-spring-center. Includes pre-greased idler hubs – with bearings, races, and seals – for 13″ to 15″ wheels.

Features:

• Round axle beam acts as part of your trailer’s suspension system
  • Replace an axle on your trailer
  • Fabricate a suspension to fit your application
• High-strength steel construction
• Bend in axle creates zero camber angle for even road-to-tread contact across the width of your trailer’s tires
  • Best for straight-line acceleration and steady, controlled towing
• Underslung design – spring seats welded to underside of axle for mounting leaf springs (sold separately)
  • Low ride height makes it easier to load and unload your trailer
• Straight, Easy Grease spindles – no drop
  • Patented welding process prevents spindle failure with 40% stronger welds
  • Built-in grease zerk for simple lubrication
• Spring seats and spindles are welded on
• Cast iron idler hubs are sturdy and durable
  • Pre-greased idler hubs with bearings, races, seals, and lug nuts – no need to pack bearings
• CSA, QAI, and SAE-N certified
• Lifetime technical support from the experts at etrailer.com

    Axle Dimensions

    
    
    There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle (when hubs are mounted on the beam).

    The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.

    If you are replacing your trailer’s axle, you should be able to figure out which type you need by determining your trailer’s capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.

     

    Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer’s tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

    Thoroughly Tested for Safety

    This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI Laboratories for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.

    Determining the Bolt Pattern

    The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

    
    
    On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2″ from the center of one hole to the center of another on the opposite side.)

    
    
    To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2″ measured to a point halfway between the opposite bolt holes.)

    
    
    Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

    • If D = 2-5/8″, then the bolt pattern is 5 on 4-1/2″
    • If D = 2-3/4″, then the bolt pattern is 5 on 4-3/4″
    • If D = 3″, then the bolt pattern is 5 on 5″
    • If D = 3-1/4″, then the bolt pattern is 5 on 5-1/2″
