Description

This 1,500 kg gull wing axle is a corrosion-resistant option for boat trailers. It comes pre-fitted with stainless steel hubs and calipers for excellent corrosion resistance. The axle beam is a 5-mm thick hollow box section designed to reduce weight while maintaining strength, and is hot dip galvanised for corrosion protection. At the hub, precision-machined stub axles ensure proper caliper alignment, while NSK bearings and stainless steel rotors provide smooth, consistent braking performance.

FAQs

Q: What are Japanese NSK bearings?

NSK is a leading Japanese manufacturer of high-performance bearings known for precision engineering and durability. The LM67048 and LM11949 tapered roller bearings included in this kit offer excellent load capacity, smooth operation, and long service life—making them a trusted choice for demanding trailer applications.

Q: What are the advantages of using box section beams for axles?

A: Box section beams (hollow tube axles) offer significant weight savings without compromising strength for most applications. Their lighter construction allows for increased payload capacity, easier handling during installation, and faster fabrication turnaround. They also allow for easy customisation, making them a flexible choice for trailer builders.

Q: Does the axle include brake pads?

A: Yes. The calipers are supplied complete with brake pads fitted. Replacement pads are available separately.

Q: What braking system is needed to operate the hydraulic disc brakes?

A: This set can be used with a hydraulic override coupling fitted to the trailer drawbar. You may also opt to install an electric-over-hydraulic kit if you prefer to have more braking options, and if you want the ability to control the brake from inside the towing vehicle.

Our HydroBrake EOH actuator and controller kits are excellent options. Please visit this page to learn more:
